Straight seam steel pipes are steel pipes with welds that are longitudinally parallel to the steel pipe. They are usually divided into metric electric welded steel pipes, electric welded thin-walled pipes, transformer cooling oil pipes, etc. The production process of straight seam welded pipe is sim
Anti-corrosion spiral steel pipes play an important and different role in people's daily lives. Anti-corrosion spiral steel pipes generally refer to the use of special technology to treat ordinary spiral steel pipes that have been anti-corrosion treated, so that the spiral steel pipes have certain a
Anti-corrosion of large-diameter spiral steel pipelines means that when large-diameter spiral steel pipelines are used and transported, the pipelines are affected by the use environment and the transportation medium, causing chemical or electrochemical reactions to cause corrosion of the pipelines.
1. Weldability: Different product uses have different requirements for welding performance. Category I tableware generally does not require welding performance, even for some pot-type companies. But most products require raw materials with good welding performance, such as second-class tableware, th
Thick-walled steel pipes are stipulated in the project: the corresponding laws and regulations for the actual selection and use of thick-walled pipe fittings. When thick-walled steel pipes are selected or used, thick-walled pipe fittings must first comply with the corresponding laws and regulations,
If the spiral steel pipe for water transportation is to transport tap water or drinking water, the inner wall is generally made of IPN8710 non-toxic anti-corrosion coating, and the outer wall is made of epoxy coal pitch anti-corrosion. Of course, it can also be coated with internal and external plas
1) Natural gas pipelines in operation: Remove accumulated water, light oil, methane hydrate, iron oxide, carbide dust, carbon disulfide, hydrosulfuric acid, and other corrosive substances inside the pipeline; reduce corrosion damage to the inner wall of the steel pipeline caused by corrosive substan
Spiral steel pipe is a long steel pipe with a hollow cross-section and no seams around it. Steel pipes have hollow sections and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water and certain solid materials. Compared with solid
There are three connection methods for galvanized steel pipes:1. Rolling groove connectionRoll groove weld cracking:① Grind the welding bars on the inner wall of the pressure groove of the pipe mouth to reduce the resistance of the rolling groove;②Adjust the axis of the steel pipe and the rolling gr
