Details of Industrial ASME SA312 TP321H Stainless Steel Welded Pipe
Before we delve into the ASME SA312 TP321H stainless steel welded pipe, we first need to have a comprehensive understanding of the ASME (American Society of Mechanical Engineers) standard system to which it belongs and the characteristics of TP321H material. ASME standards are...Read more -
Production principle of hot-rolled seamless steel pipe
The production process of hot-rolled solid ingots is to roll them into hollow tubes with no seams around them. Hot rolling can be used to produce seamless steel pipes made of carbon steel, alloy, high alloy steel, and some non-ferrous metals, with an outer diameter range of 16...Read more -
What is the problem of low impact toughness in the weld zone of S135 drill pipe friction welding
An oil drill pipe is an oilfield drilling tool and the main component of the oil drill string. It plays the role of connecting the drill string, conveying mud, and transmitting torque during drilling. It is subjected to complex loads such as compression, tension, torsion, and ...Read more -
Quality defects and prevention of oil well pipes
Quality defects of oil well pipes mainly come from three aspects: First: quality defects of the oil well pipe body itself, such as mechanical properties, internal pass, weighing, etc. of the pipe body that do not meet the requirements; Second: quality defects of oil well pipes...Read more -
Why is the surface of 304 stainless steel plate rough after deep drawing
After 304 stainless steel plate is stretched and formed, its surface sometimes appears rough, which is called the orange peel phenomenon. As the name implies, the surface texture is like orange peel, and it feels a bit rough to the touch. This is different from the smooth surf...Read more -
What is the purpose of pickling seamless steel pipes
Pickling and passivation of seamless steel pipes is a chemical reaction. First, the pickling solution can remove the scale and rust on the surface of steel, and the passivation process is completed at the same time. It can effectively prevent the oxidation of seamless steel pi...Read more
