What is the suitable temperature for welding straight seam steel pipe
Welding, also known as welding, is a manufacturing process and technology that can join metal or other thermoplastic composite materials such as plastics by applying heat, high temperature, or pressure. There are three welding methods: 1. Welding. The workpiece is heated to form a molten pool. Af...Read more -
Defects that are prone to occur in the welding zone of spiral steel pipes
The defects that are easy to occur in the welding area of the spiral steel pipe include air holes, thermal cracks, and undercuts. Spiral steel pipe weld porosity not only affects the tightness of the pipe weld, causing pipeline leakage but also becomes a corrosion induction point, seriously reduc...Read more -
What is the difference between stainless steel pipe fittings, welded pipe fittings, and seamless pipe fittings
1. Different pressure bearing capacity: The working pressure that welded steel pipe fittings can generally withstand is within 20 kg, which is the safest range of use. It is generally used for low-pressure fluids such as water, gas, and compressed air; seamless steel pipe fittings can withstand u...Read more -
Technical progress of straight seam steel pipe rolling
Technical progress of straight seam steel pipe rolling: 1) Increase the thermal charging temperature and thermal charging ratio: Increasing the thermal charging temperature and thermal charging ratio is an important measure for energy saving and emission reduction, and has attracted much attentio...Read more -
Expanding Technology and Classification of Straight Seam Steel Pipe
In terms of the welding process, the welding method of spiral welded pipe and straight seam steel pipe is the same, but the straight seam welded pipe will inevitably have a lot of T-shaped welds, so the probability of welding defects is also greatly increased, and the welding residue at the T-sha...Read more -
Processing technology and inspection steps of straight seam steel pipe
In the production process of straight seam steel pipe, the processing method will have a lot of influence on it. So what are the processing methods for straight seam steel pipes? The staff of the manufacturer will introduce the main methods for you. Using the repeated impact of the forging hammer...Read more
