High pressure boiler tube manufacturing method:
(1) general boiler tube temperature in use is under 450 ℃, the domestic pipe mainly use 10, 20 carbon steel hot rolled seamless steel pipe or cold drawn seamless steel pipe.
(2) high pressure boiler tubes are often used in high temperature and high pressure conditions, when using the pipe under the action of high temperature flue gas and water vapor, oxidation and corrosion will happen. It requires steel pipe with high rupture strength, high oxidation corrosion resistance, and have good organizational stability.
High pressure boiler tube USES:
(1) general boiler tube is mainly used to produce water wall tube, water pipe, superheated steam tube, locomotive boiler superheated steam pipe, large and small pipe and tube arch brick, etc.
(2) high pressure boiler tube is mainly used to manufacture high-pressure and ultrahigh-pressure boiler superheater tubes, reheater tube, airway, and main steam pipe, etc.
The high temperature performance of high pressure boiler tube is divided into general boiler tube and high pressure boiler tube.
No matter general boiler tube or high pressure boiler tube according to the different requirements for their use and can be divided into various kinds of seamless steel pipe.
High pressure boiler tube specifications: 8-1200 x 1-200 - mm
High pressure boiler tube executive standard: GB3087-1999, 20G high pressure boiler tube, GB5310-1999 GB/T5310-2008 - China's national standards ASME SA106 - the boiler and pressure vessel code ASME SA210 - the boiler and pressure vessel code ASME SA213 - the boiler and pressure vessel code DIN17175 - the German industrial standards.
