Professional production: boiler tubes, large diameter boiler tubes, boiler tubes of small diameter, thick-walled boiler tubes, boiler tubes thin-walled, small-diameter thin-walled boiler tubes, boiler tubes of small diameter thick-walled, large diameter thin-walled boiler tubes, boiler tubes of large diameter thick-walled 
 High-pressure boiler tubes is a boiler tube, seamless steel tubes are categories. Seamless pipe manufacturing methods and the same, but the steel used in the manufacture of steel, there are strict requirements. 20G high-pressure boiler tubes often used in high temperature and high pressure conditions, high temperature gas and water vapor in the tube under the effect of oxidation and corrosion will occur. Requires durable steel with high strength, high corrosion resistance to oxidation and have good organizational stability. High-pressure boiler tubes used to manufacture high pressure and high pressure main boiler superheater tubes, reheater tubes, airway, the main steam pipe. 
 Standard high-pressure boiler tubes 
 GB3087-2008 - China National Standard 
 GB5310 -2008 - Chinese national standard high-pressure boiler tubes 
 ASME SA106 ------- American Boiler and Pressure Vessel Code 
 ASME SA210 - American Boiler and Pressure Vessel Code, ASME SA213 - American Boiler and Pressure Vessel Code 
 DIN17175 - German industrial standard 
 Uses high-pressure boiler tubes: 
 For low and medium pressure boiler (working pressure not higher than 5.88Mpa, operating temperature below 450 ℃) of the heating surface tubes; for high-pressure boiler (working pressure is generally more than 9.8Mpa, the working temperature of 450 ℃ ~ 650 ℃ rooms) of the heating surface tubes, economizer, superheater, reheater, petrochemical industry pipe. 
 High pressure boiler tube specifications and appearance quality 
 Specifications and appearance quality: GB5310-95 high-pressure boiler tube diameter 22 ~ 530mm, wall thickness 20 ~ 70mm range. Cold drawn (cold) pipe diameter 10 ~ 108mm, wall thickness 2.0 ~ 13.0mm range. 
 High-pressure boiler tubes major grades: 10,20,20 G, 20MnG, 25MnG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, 12Cr2MoWVTiB, 10Cr9Mo1VNb, SA210A1, SA210C, SA213 T11, SA213 T12, SA213 T22, SA213 T23, SA213 T91, SA213 T92, ST45. 8 / Ⅲ, 15Mo3, 13CrMo44, 10CrMo910 etc. 
 High Pressure Boiler Tube Tolerance 
 Diameter steel pipe type (D) wall thickness (S) cold drawn steel tube diameter (mm) Tolerance (mm) pipe wall thickness (mm) Tolerance (mm)> 30 ~ 50 ± 0.3> 3 ~ 20 ± 10% 
 High Pressure Boiler Tube weight formula: [(OD - Wall Thickness) * Thickness] * 0.02466 = kg / m (the weight per meter)
