nm500 steel equivalent for lower than ambient temperature service

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, NM500 steel equivalent, 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.

API 5CT N80 casing pipe is important equipment for oil drilling . API 5CT N80 casing pipe main application is to support the sidewall of the oil well during drilling. API 5CT N80 oil casing pipe plays an important role to guarantee the normal operation of the whole well drilling work.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized NM500 steel equivalent are higher than that of annealed NM500 steel equivalent, but the elimination of internal stress is not as good as annealing. The normalizing operation of NM500 steel equivalent is simple, the cost is low, the productivity is high, and it is widely used in actual production.
