Product Description

GB3087-1999 Seamless Steel Tubes for Low and Medium Pressure Boilers

Low and medium pressure boiler tube made by Hot rolling(extrusion), cold drawn or cold rolled, According to Chinese standard GB 3087-1999

A leading manufacturer of Seamless Boiler Steel Tubes in China, offers high quality Steel Heat Exchanger Tubes,Seamless Carbon Boiler Tube,Alloy Steel Boiler Tube

This seamless boiler tube is used for low and medium pressure boilers. The seamless low and medium pressure boiler tube is produced with the method of Hot Rolling(Extrusion), Cold Drawn or Cold Rolled, according to the Chinese standard GB 3087-1999.


GB3087-1999 steel is an industry term that refers to the reference steel pipe, steel ingot is made of perforated or solid through the capillary tube, and then hot-rolled, cold-rolled or cold call is made. Hot-rolled seamless steel tube includes normal tubes, low and medium pressure boiler pipe, high pressure boiler pipe, steel pipe, Stainless Steel Pipe, oil cracking pipe, geological steel pipes and other steel pipe.


Application of the seamless boiler tube: For low and medium pressure boilers.

Produce method for low and medium pressure boiler tube: Hot rolling(extrusion), cold drawn, cold rolled.

The seamless low and medium pressure boiler tubes` material:20#/30#/35#/45#/16Mn/5MnV/40Cr/30CrMnSi/45Mn2/40MnB/15MoG/20MoG/12CrMoG and so on


Seamless low-pressure boiler pipe: for the manufacture of a variety of low and medium pressure boiler superheated steam pipes, boiling water pipe, water wall tubes and superheated steam locomotive boiler tubes, opium pipe, small pipe and brick arch tubes. (Dial) seamless steel pipe with high quality carbon structural steel hot or cold. 10,20 steel is mainly used, in addition to chemical composition and mechanical properties do hydrostatic testing, curling, flaring, flattening and other tests. State of delivery hot rolled, cold-rolled (dial) to heat treatment delivery.

Tolerance of low and medium pressure boiler tube:

  1. Tolerance of the OD &WT:
  2. Bending tolerance:

    WT≤15mm, Bending≤1.5mm/m

    WT>15mm, Bending≤2.0mm/m

    OD≥351mm, Bending≤3.0mm/m

Tests of the seamless boiler tubes:

  1. Bending Test: The tubes should take the bending test when OD ≤22mm. The bending Angle is 90 degrees, and the bending radius is 6 times the outer diameter of the steel tube.
  2. Hydraulic test: Eddy current testing, ultrasonic testing can be used instead of hydraulic tests. When eddy current testing, GB/T 7735-1995 Gr. A should be followed; when ultrasonic testing, GB/T 5777-1996 Gr. C8 should be followed.
  3. Flattening test
  4. Flanging test
  5. Expand test
