Product Description

Product Description

Carbon steel pipe is made of steel ingot or solid tube billet by perforation, and then hot rolling, cold rolling or cold drawing. Carbon steel pipe has an important position in Chinese steel pipe industry. According to incomplete statistics, our existing carbon steel pipe production enterprises about 240, carbon steel pipe sets about more than 250 sets, annual capacity of about more than 4.5 million tons. From the caliber, <φ76, accounting for 35%, <φ159-650, accounting for 25%. From the variety, the general purpose tube 1.9 million tons, accounting for 54%; 760,000 tons of petroleum steel pipe, accounting for 5.7%; Hydraulic prop, precision pipe 150,000 tons, accounting for 4.3% stainless pipe bearing pipe, auto pipe 50,000 tons, accounting for 1.4%.

 
GB 5310 standard is applicable to steam boilers and pipeline seamless pipes for the manufacture of high pressure and above.

20G steel pipe is GB / 5310 national standard steel grade (foreign corresponding brands: Germany ST45.8, Japan stb42, America sa106b), which is the most commonly used boiler steel pipe.

GB / 5310 20G steel pipe has certain strength at normal and medium high temperature, low carbon content, better plasticity and toughness, and good cold and hot forming and welding performance.

 

GB 5310 20G Seamless steel tubes and pipes for high pressure boiler
20G (high quality carbon structural steel pipe) supplied according to GB5310 is used as heating surface pipe fittings, and the maximum wall temperature for long-term use is ≤ 450 ° C. when GB5310 20G seamless steel pipe is used as header and steam pipe, the long-term use temperature shall be ≤ 425 ° C.
