NM550 steel price list,Welded steel pipe refers to the steel pipe with a joint on the surface which is welded after the steel strip or steel plate is bent and deformed into circular, square and other expected shapes. According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe, NM550 steel price list, etc. According to the weld shape, it can be divided into straight welded pipe and spiral welded pipe. Electric welded steel pipes are mainly used in oil drilling and production, machinery manufacturing, etc.; furnace welded pipes can be used as water gas pipes, large-diameter straight seam welded pipes for high-pressure oil-gas transmission, etc.; spiral welded pipes are used for oil-gas transmission, pipe piles, piers, etc. Welded steel pipe has lower cost and higher production efficiency than seamless steel pipe.

Compared with , boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point (2) Good plasticity, impact toughness, cold bending and welding performance (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small,NM550 steel price list.

NM550 steel price list,X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.NM550 steel price list
