Material characteristics and pressure-bearing capacity of large-diameter internal and external plastic-coated steel pipes
First, the material characteristics of large-diameter internal and external plastic-coated steel pipes: 1. Plastic coating: The inner and outer layers of large-diameter internal and external plastic-coated steel pipes are protected by plastic coatings. This kind of coating has good corrosion resi...Read more -
Classification and various uses of welded steel pipes
First, classification of welded steel pipes are classified according to their uses: According to their uses, they are divided into generally welded steel pipes, galvanized welded steel pipes, oxygen-blown welded steel pipes, wire casings, metric welded steel pipes, idler pipes, deep well pump pip...Read more -
What are the effects of carbon and silicon in the chemical elements of seamless steel pipes on the properties of steel
The effects of carbon and silicon in the chemical elements of seamless steel pipes on the properties of steel are as follows: 1. Carbon (C): Carbon is the main element second only to iron in the steel used for seamless steel pipes. As the carbon content increases, the strength of the steel increa...Read more -
Explore the industrial details of large-diameter thick-walled seamless steel pipes
Large-diameter thick-walled seamless steel pipes are mainly reflected in: 1. Large diameter: It is generally believed that seamless steel pipes with diameters above 219 are large-diameter seamless pipes, those with diameters less than 76 are small-diameter seamless pipes, and those in the middle ...Read more -
The difference between ERW (straight seam resistance welded steel pipe) steel pipe and HFW (high frequency welded steel pipe) steel pipe
As the name suggests, resistance welding is a method in which pressure is applied through electrodes after the welding parts are assembled, and the resistance heat generated by current passing through the contact surface of the joint and adjacent areas is used for welding. High-frequency welding:...Read more -
Frequently Asked Questions about Spiral Steel Pipe Dredging
When the spiral steel pipe is blocked, it will not only affect our use but also have a certain corrosion effect on some materials inside the spiral steel pipe. Therefore, it will have very bad effects if it is not cleared in time. The first is to flush with water and use the pressure of water to ...Read more -
Performance of industrial 316 capillary stainless steel pipe
Capillary stainless steel tubes generally refer to thin tubes with an inner diameter of less than or equal to 1 mm. Because the diameter of such tubes is as thin as hair, they are called capillary tubes. Its use cases include medicine, building materials, automation instrument signal tubes, instr...Read more -
Surface treatment of thick-walled straight seam steel pipe
The uniformity of the wall of thick-walled straight-seam steel pipes will directly affect the later processing of parts. The wall of thick-walled straight-seam steel pipes cannot be controlled, which means that the overall steel pipe cannot be strictly controlled. Small and medium-sized steel, wi...Read more -
What are the differences between hot-rolled steel plates and cold-rolled steel plates
The carbon content of hot-rolled steel plates is slightly higher than that of cold-rolled steel plates. The density is the same even if the ingredients are not much different. But if the ingredients are very different, for example, the density of stainless steel, regardless of cold-rolled or hot-...Read more -
Why steel pipe quenching needs to be tempered
The main reasons for tempering steel pipes after quenching are as follows: 1. Obtain the required mechanical properties: the strength and hardness of the steel pipe after quenching is greatly improved, but the plasticity and toughness are significantly reduced. Tempering treatment can improve the...Read more -
Post-processing and maintenance of galvanized steel pipes
Galvanized steel pipe, a material widely used in the construction industry and many other fields, has won the favor of the market with its excellent corrosion resistance, strength, and ease of processing. However, even such high-quality materials require proper handling and maintenance during use...Read more -
Will industrial cold-rolled square steel pipes rust
When we purchase a new cold-rolled square steel pipe product, whether it is used in construction, furniture, or other fields, we hope that it will remain as smooth as new and will not rust. However, the reality is that some cold-rolled square steel pipe products do tend to rust over time. So, wil...Read more
