Boiler tube

Boiler tube Definition

Boiler pipe is one kind of seamless pipe, and their production style is same. However boiler pipe has strict requirement for steel grade used. According to the usage temperature differences, boiler pipe can be divided into general boiler tube and high pressure boiler pipe. Different country have their own standard for boiler pipes, and they are widely used for heating surface of high temperature boiler, heater, economizer, super heater, re-heater, and petrochemical industry and so on.

Production Size Range: OD 21.3mm to 508mm x WT 3mm to 50mm Main standards consist of DIN17175, EN10216, ASME SA-106M, SA-192M, SA-209M, SA-210M, SA-213M, SA-335M, GB3087, GB5310, JIS G3456, JIS G3461, JIS G3462.

FAQ

11.What is the difference between high pressure boiler tubes and low and medium pressure boiler tubes?
The differences between high pressure boiler tubes and zhi low and medium pressure boiler tubes are as follows:
A.the execution standards is different
B.Different use environments High pressure boiler tubes: the working pressure is generally above 9.8Mpa, and the working temperature is between 450℃ and 650℃ Low and medium pressure boiler tubes: the working pressure is generally not more than 5.88Mpa, and the working temperature is below 450℃
C.Different materials Suitable materials for high pressure boiler tubes: 20G, 20MnG, 25MnG, 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc. Suitable materials for low and medium pressure boiler tubes: 10#, 20#
D.Different prices The price of high pressure boiler tubes is higher than that of low and medium pressure boiler tubes.
22.The difference on materials between fluid pipe and boiler pipe?
The working environment of fluid pipe is relatively peaceful Boiler tubes have low carbon, strict control of harmful elements, no segregation of carbon elements and good welding performance
3Why should boiler tubes be heat treated?
Stress concentration will occur after bending. Heat treatment is mainly to eliminate stress.
