API 5L X46 Pipe Specifications
The minimum yield strength of API 5L X46 pipe is approximately 317 MPA. These grades of pipe have chemical and mechanical properties superior to API 5L Grade B and API 5L X42 Grade pipe. This grade is known for its heavy-duty and high performance, making it cost-effective. Due to their high mechanical strength, these pipes have a robust structure, high resistance to cuts and precise dimensions. API 5L grade PSL1 X46 pipe is often chosen by customers looking for better performance than grade B and X42 pipe.

API 5L X42 Pipe Specifications
API 5L X42 pipe has a minimum yield strength of 290 MPA, enabling it to operate in low to medium pressure pipes. These grades of pipe are superior to API 5L Grade B pipe in terms of chemical and mechanical properties. It has higher mechanical strength than API 5L Class B pipe and is therefore less susceptible to cracking. For industrial applications requiring higher strength pipes, customers prefer API 5L GR. X42 pipe replaces API 5L Class B.

Spiral Welded Pipe and ERW Pipe
Manufacturing process
A.ERW pipe manufacturing process:
Electric resistance welded (ERW) pipe is produced using a relatively simple but efficient manufacturing process. It starts with flat steel strip unrolled from a roll and passed through a series of rollers to ensure uniform thickness. The strip then enters the welding chamber, where high-frequency current is applied to the edges of the strip. This localized heating causes the edges to melt and fuse together, forming a continuous weld. Finally, the welded pipe is cut to the required length and subjected to various finishing processes such as straightening and inspection.

What Is Q235 Carbon Steel?
Q235 Steel (Q235A Q235B Q235C Q235D)
Q235 steel is a common carbon structural steel widely used in my country. The Q235 material in Chinese standard GB/T 700 is divided into 4 quality grades: Q235A, Q235B, Q235C and Q235D; the density of the steel is 7.85 g/cm3, and the tensile strength is 370-500 MPa; Yield strength is 235MPa (data is for steel bars or steel plates with a diameter less than or equal to 16mm). Since it is mild steel, it can be used directly without heat treatment.

Performance of stainless steel pipes
The special properties of stainless steel pipes are:
1. Excellent corrosion resistance: A thin protective film will form on the surface of stainless steel. Although this protective film is about 3×10-6 mm, it is very strong. Even if it is damaged, as long as there is oxygen next to it, it will It can be regenerated immediately to prevent rust.
