Three common sense galvanized steel pipe

After long-term research and experiments, hot dip galvanizing has the advantages of long durability, high industrialization and stable quality. Therefore, 3 inch galvanized square steel tubing it is widely used in outdoor steel structures that are subject to atmospheric corrosion and are difficult to repair. Hot dip galvanizing is widely used in power towers, communication towers, railways, highway protection, streetlight poles, marine components, building steel structural components, substation ancillary facilities, light industry, etc.

The galvanized steel pipe is based on a welded pipe and is coated with a layer of zinc for the purpose of preventing rust and corrosion, each of which is 6 m long. Galvanized pipes are divided into hot-dip galvanizing and electro-galvanizing (also known as cold-galvanizing).

One, special point:

Features of hot-dip galvanizing: thick galvanized layer, the latest national standard GB/T3091-2015, it is necessary to ensure the galvanizing capacity of 300g/m2, with uniform coating, strong adhesion and long service life.

Characteristics of cold galvanizing: The amount of galvanizing is very small, only 10-50g/m2, and its corrosion resistance is much worse than that of hot-dip galvanized pipe.

Two, Production Process:

Black parts inspection→hanging→degreasing→rinsing→acid washing→cleaning→dipping assisted plating→hot air drying→hot dip galvanizing→cooling→passivation and rinsing→unloading→inspection, finishing→packaging, transportation.

Three, main use:

1. Fire protection facilities.

Because it has the advantage of preventing rust and preventing corrosion, it is widely used in fire hoses.

The current fire water supply pipe is basically a galvanized pipe. The main body of the fire pipe: mainly used DN100*4.0 and DN100*4.5 international galvanized pipe to reach the pressure of 1.6pa, the national standard regulations are to be used The thickness of the international can be used as the main fire pipe, but in actual use, it can also be according to the actual floor, the actual pressure bearing range, the corresponding thickness can be selected, hot rolled seamless steel pipe factory and the corresponding cost can be reduced! Now whether it is a large number of fire pipes, Or the fire tube in the basement, basically using galvanized pipe, and then coating a layer of paint on the outer layer of the galvanized pipe, so that everyone can see the red fire pipe, which is actually formed by galvanizing pipe processing.

2.Agricultural pipes.

Speaking of agricultural pipes, many people are still very strange. Many people think that many agricultural plants use bamboo wood directly. Nowadays, many people use galvanized pipes directly for agricultural use. They are mainly used to build warm greenhouses for flower sheds. There are columns for making flowers and melons. The most used ones are galvanized tubes with 4 points * 1.7 thickness and 6 points * 1.7 thickness. They have a simple requirement for galvanized tubes to bend, so this material is selected. It is also very important.

3, trachea.

The iron pipe used for gas and heating is also a galvanized pipe.

4, structural tube.

Commonly used steel structure, welding engineering, now many scaffolding plants outside, the former building is welded steel pipe, but the welded steel pipe is easy to rust, in order to prevent rust and a layer of paint, in order to solve this problem, Many new steel structures are now directly using galvanized pipes, which saves time and can be used for a longer period of time. The general welding project will use relatively thin galvanized pipes, generally two levels under the international level, and the requirements for steel pipes are not so high.

5.Water pipes.

In the old houses, the water pipes used in the old houses were all galvanized steel pipes. After a few years of use, a large amount of rust was generated inside the pipes. The yellow water flowing out not only polluted the sanitary ware, but also mixed with the bacteria that grew on the uneven inner wall. The rust caused the heavy metal content in the water to be too high. , seriously endangering the health of the human body.

The reasons for the crack of the battery

Crack, hot spot and PID effect are three important factors affecting the performance of crystalline silicon photovoltaic modules c channel purlins for sale. This article takes everyone to understand the reasons for the crack of the battery, how to identify and prevent it.

1. What is “hidden crack”

Cryptation is a relatively common defect in crystalline silicon photovoltaic modules. In general, it is micro-crack that is invisible to the naked eye. The crystalline silicon component is very susceptible to cracking due to its own crystal structure.

In the process of producing crystalline silicon components, many links may cause the cell to crack. The root cause of cracking can be summarized as mechanical stress or thermal stress on the silicon wafer. Now in order to reduce the cost, the crystalline silicon cell is developing in a thinner and thinner direction, which reduces the ability of the cell to prevent mechanical damage and is more prone to cracking.

2. The impact of “cracking” on component performance

The current generated by the cell is mainly collected and derived by the main gate lines and the fine grid lines whose surfaces are perpendicular to each other. Therefore, when a crack (mostly a crack parallel to the main gate line) causes the fine gate line to break, the current will not be efficiently transported to the main gate line, causing the cell portion or even the entire chip to fail, possibly causing debris, Hot spots, etc., while causing power attenuation of the component.

The crack perpendicular to the main gate line hardly affects the fine gate line, so the area where the cell fails is almost zero.

However, in the rapid development of thin film solar cells, due to their material and structural characteristics, there is no problem of cracking. At the same time, the surface collects and transmits current through a transparent conductive film, and even if the battery sheet has a small flaw, the conductive film is broken, which will not cause a large area failure of the battery.

Studies have shown that if the failure area of ​​a battery in a component is less than 8%, the power of the component is not affected, and the 2/3 diagonal stripe crack in the component has no effect on the power of the component. Therefore, although cracking is a common problem with crystalline silicon cells, there is no need to worry too much.

3. Reasons for the formation of “cracking”

External force: The battery piece will be subjected to external force during welding, lamination, frame or handling, installation, construction, etc. When the parameters are improperly set, equipment failure or improper operation will cause cracking.

High temperature: The battery sheet is not preheated at low temperature, and then it will cause cracking when it is suddenly exposed to high temperature in a short time. For example, the welding temperature is too high, and the lamination temperature is unreasonable.

Raw materials: Defects in raw materials are also one of the main factors leading to cracking.

4. Identify the “crack” method

EL (Electroluminescence) is an internal defect detection device for solar cells or components. It is a simple and effective method for detecting cracks. Using the electroluminescence principle of crystalline silicon, the near-infrared image of the component is captured by a high-resolution infrared camera to acquire and determine component defects. It has the advantages of high sensitivity, fast detection speed and intuitive image.

5. Points to prevent cracking of PV modules

In the production process and subsequent storage, transportation, installation, the battery is protected from improper external force, and the storage environment temperature range is also noted.

In the welding process, the temperature of the battery should be preheated (hand soldered) to meet the requirements.

A Substance Information Exchange Forum (SIEF) has been set up for several kinds of mineral wool. If you will be doing the interior of your own home than I’d suggest trying into mineral wool insulation, because it is among the most secure and efficient types.

Rockwool insulation is safe from rodents. The effectivity and superiority of Rockwool is due to plenty of causes associated to its composition. Nevertheless, there are just a few other viable supplies which you could additionally choose from like polyurethane foam, rock wool and even cellulose. This makes it more efficient to dye than wool, as one dye makes 8 colored Rockwool without delay. Rockwool Develop Blocks: Rockwool Grow Blocks are full-sized growing mediums for transplanting barely bigger seedlings, with a few small leaves and roots rising from starter cubes.

Rockwool insulation is an efficient conductor of warmth. There are a variety of advantages to using mineral wool insulation. At ROCKWOOL, we’re committed to enriching the lives of everyone who experiences our product solutions. Since Rockwool incorporates a good quantity of mineral oil (a natural water repellent), you will need to seek out prime quality Rockwool that has had a lot of the water eliminated during manufacture and has also had a wetting agent added to the mineral combine.

The center segments of photovoltaic power age

Photovoltaic modules are the center segments of photovoltaic power age. So as to work typically in photovoltaic power plants, it is important to assess and keep up the segments of photovoltaic power plants. Sun powered modules: likewise called sun based boards Hot dipped galvanized steel square tubing, as a rule by sunlight based cells, as indicated by a specific power. z profile steel supplier,And size prerequisites, a lot of intensity age units comprising of circuit associations and bundled together by an edge. The parts are the fundamental structure squares of a photovoltaic power age framework.

1.Actively check the fiery debris and soil of the parts. On the off chance that the fiery debris and earth are not kidding, it is important to organize cleaning.

2.Fully comprehend the parameters of PV modules, make definite activity and upkeep plans for focused activity and support of PV modules, and make arrangements as indicated by necessities.

3.The decision of cleaning time

The cleaning of photovoltaic modules of photovoltaic power plants ought to be done in the first part of the day, night, night or blustery days. It is carefully illegal to pick cleaning previously or evening or during times of solid daylight. For the most part think about the accompanying two reasons: to forestall the loss of photovoltaic cluster control age brought about by counterfeit shadows, and even the problem area impact; the surface temperature of the segments is very high around early afternoon or when the light is great, keeping cold water from causing glass or glass surface Component harm.

Simultaneously, in the first part of the day and night cleaning, it is likewise important to choose the timeframe when the daylight is feeble. It is additionally possible to do cleaning work in some cases blustery climate. Right now, the cleaning procedure is generally proficient and exhaustive in light of the assistance of precipitation. The cleaning procedure should focus on faculty wellbeing and wear security gear to avert spillage and knocks. It is carefully taboo to venture on or generally acquire the part board and section during the cleaning procedure.

Cleaning cycle and zone arranging. Since enormous scale photovoltaic power plants involve a huge territory, the quantity of segments is huge, and the time required for cleaning tasks is short each day, the cleaning of photovoltaic power plants should be arranged by the electrical structure of the power station to diminish the loss of intensity age.

4.cleaning advances.

Customary cleaning can be separated into general cleaning and flushing cleaning.

One.Ordinary cleaning, utilize a dry little sweeper or cloth to breadth off the outside of the PV module, for example, dry drifting fiery debris, leaves, and so forth. For hard outside articles, for example, earth, winged animal droppings, and gooey items appended to the glass, scratching might be performed with a somewhat hard edge or bandage, yet care must be taken not to utilize a hard material to scratch and anticipate harm to the glass surface. Regardless of whether it is important to perform cleaning and cleaning as far as cleaning impact. omega profile maker

Two.Rinse and clean. For articles that are near the glass and have stains, for example, winged animal droppings, plant squeeze, or wet soil, which can’t be cleaned, they should be cleaned. The cleaning procedure is for the most part done with clean water and with an adaptable brush. On the off chance that slick earth or the like is experienced, the tainted territory might be independently cleaned with cleanser or lathery water.

Note: Wipe the PV module with a dry or clammy delicate and clean material. Try not to utilize destructive solvents or wipe the PV module with a hard object. The PV module ought to be cleaned at an irradiance of under 200W/m2. Fluid cleaning parts with huge temperature contrast of segments; it is carefully prohibited to clean PV modules under meteorological conditions with wind power more prominent than 4, substantial downpour or overwhelming day off; notice signs on the PV modules must not be lost; check the association of the intersection boxes of the segments, regardless of whether there is detachment or warmth , staining wonder, and auspicious handling.
