Product Description

GB5310-1999 Seamless Steel Tubes for High Pressure Boilers

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

Seamless High pressure boiler tube is hot rolling(extrusion), cold drawn or cold rolled tubes, made according to Chinese standard GB 5310-1995

This tube is used for high pressure boilers. The seamless high pressure boiler tube is produced with the method of Hot Rolling(Extrusion), Cold Drawn or Cold Rolled, according to the Chinese standard GB 5310-1995.

GB5310-1995, one kind of seamless steel tubes, mainly used to manufacture high pressure steam boiler and above pipelines with high-quality carbon steel, alloy steel and heat-resistant seamless Stainless Steel Tubes.

Feature of seamless high pressure boiler tube: Persistent high strength, high oxidation resistance, good organizational stability

Application of the seamless boiler tube: For high pressure boilers.

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

The seamless high pressure boiler tubes` material:

20#/20G/15MnG/20MnG/15MoG/20MoG/16Mn/15CrMo/15CrMoG/12Cr1MoV/12Cr1MoVG/Cr5Mo/10CrMo910 and so on.

The boiler tubes often work in high temperature and high pressure, pipe in high temperature smoke and steam will meet oxidation and corrosion, thus it requires a durable steel Persistent high strength, high oxidation resistance, good organizational stability.

Seamless high-pressure boiler pipe: for the manufacture of a variety of high 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. 20# steel is mainly used, in addition to chemical composition and mechanical properties will do hydrostatic testing, curling, flaring, flattening and other tests. State of delivery hot rolled, cold-rolled (dial) to heat treatment delivery.

WT30 mm, Bending3.0mm/m

3. End shape for the seamless high pressure boiler tube:

Both ends of the pipe should be cut at right angles, and remove burrs

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
