Boiler Steel Tubes Implementation Of Standards
Boiler Steel Tubes Implementation of standards
The medium and low pressure boiler tubes are made of steel ingots or solid tubes through perforations and then made by hot rolling, cold rolling or cold blowing. Seamless steel pipe in China's steel industry has an important position. According to incomplete statistics, China's existing seamless pipe production enterprises more than 240, seamless steel pipe units of about 250 sets, with an annual output capacity of about 450 million tons. From the caliber, <φ76, accounting for 35%, <φ159-650, accounting for 25%. From the species, the general use of pipe 1.9 million tons, accounting for 54%; oil pipe 76 million tons, accounting for 5.7%; hydraulic pillars, precision pipe 150,000 tons, accounting for 4.3%; stainless steel pipe, Ton, accounting for 1.4%.
Low - pressure boiler tubes in the implementation of standards: GB3087-1999 low pressure boiler seamless steel pipe.
In the low-pressure boiler tube is used to create a variety of low-medium pressure boiler superheated steam pipe, rolling pipe and locomotive boiler with superheated steam pipe, large smoke pipe, small pipe and arched brick with high-quality carbon structural steel hot and cold Pull (rolling) seamless tube. Mainly used for industrial boilers and live boilers transport low and medium pressure fluid pipeline. Representative material for the 10,20 steel. In the low-pressure boiler tube can be divided into the following categories.
1, the use of seamless steel pipe: GB / T8162-2008 2, the transport fluid with seam steel pipe: GB / T8163-2008 3, the boiler seamless steel pipe: GB3087-1999 4, high pressure seamless pipe boiler: GB5310-1995 ( ST45.8-Ⅲ type) 5, high-pressure seamless steel pipe equipment: GB6479-2000 6, Seamless steel pipe for geological drilling: YB235-70 7, oil drilling seamless steel pipe: YB528-65 8, Seamless steel pipe: GB3048-1999 11, Seamless steel pipe for ships: GB5312-1999 12, cold drawn cold rolling precision Seamless steel pipe: GB3639-1999 13, a variety of alloy tube 16Mn, 27SiMn, 15CrMo, 35CrMo, 12CrMov, 20G, 40Cr, 12Cr1MoV, 15CrMo In addition, there GB / T17396-1998 (hydraulic pillar with hot-rolled seamless steel pipe), GB / T3094-1986 (cold drawn or cold rolled precision seamless steel pipe), GB / T3094-1986 (cold drawn seamless steel pipe profiled steel pipe), GB / T8713-1988 (GB / Hydraulic and pneumatic cylinder with precision diameter seamless steel pipe), GB13296-1991 (boiler, heat exchanger with stainless steel seamless steel pipe), GB / T1497 5-1994 (stainless steel seamless steel tubes for structural use), GB / T14976-1994 (seamless steel tubes for fluid delivery) GB / T5035-1993 (seamless steel tubes for automotive axle casing), API SPEC5CT-1999 (casing and Tubing specifications).
