Canghai Steel Pipe: Busy production and hot sales

On March 24, the factory's production workshop was extremely busy. In the past few days, Canghai has been focusing on epidemic prevention and production on the one hand, and has stepped up the production of spiral steel pipe orders according to market needs to meet the needs of many places inside and outside the province. Orders in the first quarter of this year did not decrease but increased, and sales increased by 100% year-on-year.

Spiral steel pipe maintenance

Use solvents and emulsions to clean the surface of the steel to remove oil, grease, dust, smoothing agents and similar organic substances, but it can not remove the rust, scale, welding flux, etc. on the surface of the steel, so it is only used as an aid in anti-corrosion.

What is the acceptance standard for straight seam welded pipe

In practice, we can use welded pipes to transport various low-pressure fluids. The products are generally made of Q195, Q215A, Q235A steel and Q235B carbon. It can also manufacture 0317 standard model 6012 and steel 755 mild steel that are easy to weld. After the production of welded pipes is completed, tests such as water pressure, bending, and flattening shall be carried out. At the same time, its surface quality also has certain requirements.

Spiral steel tube market development

Recently, railway construction has become a hot spot again, and railway construction has encountered a new development period. The re-emergence of railway construction in the west has led to the overall development of the regional economy. In addition, urban rail transit construction has also entered the fast lane. Railway construction and urban rail transit construction will It has become one of the engines of recent economic development, which has a positive effect on the increase in the amount of related steel products.

How to judge the quality of anticorrosive spiral steel pipe

The corrosion-resistant spiral steel pipe material will produce different sparks through contact with the grinding wheel. We can tell what kind of anticorrosive spiral steel pipe is made by observing the spark. Can check 301 anticorrosive spiral steel pipe belt, anticorrosive spiral steel pipe plate, anticorrosive spiral steel pipe rod, anticorrosive spiral steel pipe line, anticorrosive spiral steel pipe ...

How to manufacture large spiral steel pipe

Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made by rolling low carbon structural steel or low alloy structural steel steel strip into a tube blank at a certain spiral angle (called forming angle), and then welding the pipe seam , It can produce large diameter steel pipe with narrow strip

Sewage treatment 3PE anti-corrosion steel pipe

3PE anti-corrosion steel pipe 3PE anti-corrosion layer is suitable for the protection of pipelines with complex terrain and severe corrosion. In the construction of oil fields, 3PE anti-corrosion pipes are currently in China due to their high chemical resistance, excellent mechanical protection characteristics, long service life Oilfield oil, water and gas transmission projects dominate the application. The products are widely used in petroleum, natural gas, chemical industry, electric power, military industry, shipbuilding, papermaking, heating, water supply and drainage, hydropower stations, piling, bridges, steel structures and other pipeline engineering fields, and are well received by users.

Common sense of anticorrosive spiral pipe for drinking water pipe

The water supply of a city is very large. This caused the tap water to pass through the steel pipe, which would have a great impact on the pipeline. Under such a pressure, ordinary steel pipes are likely to be damaged. However, the spiral steel pipe is different, and its superior toughness determines that the spiral steel pipe can withstand greater pressure. And ordinary steel pipes may be easily rusted. The quality of IPN8710 drinking water pipeline anti-corrosion pipeline is a matter of concern to the purchaser *. Its quality is mainly composed of its own materials, standards, wall thickness, welds and other factors. The quality of the steel pipe is measured under the same material and standard conditions Mainly depends on the wall thickness and the quality of the weld. Due to the very wide range of spiral steel pipe users, the brackets, water pipelines and other projects that we usually see, once the quality of the spiral steel pipe is problematic, these projects will be affected, and the more serious ones will directly affect human safety. At present, the wall thickness of spiral steel pipes in the market is usually lower, so the lower difference range is better than the lower quality, and the pressure bearing capacity is stronger. The quality of the weld is mainly determined by eye or through flaw detection. The weld has no sand holes , Even welding seams are high-quality products.

Types of spiral welded pipes: spiral welded pipes are generally higher in strength than straight-seam welded pipes. Welded pipes with larger diameters can be produced with narrow blanks, and welded pipes with different diameters can be produced with blanks of the same width. But compared with the straight pipe of the same length, the length of the weld is increased by 30-100%, and the production speed is lower. Therefore, most of the smaller-diameter welded pipes use straight seam welding, and the larger-diameter welded pipes mostly use spiral welded pipes.
