Winsteel Group provides seamless pipes for the high-pressure cylinders. It is our responsibility to choose the most appropriate product for customers with different use purposes, fuel, the hydraulic, trailer, a station with gas bottle, etc. Seamless steel pipe has better mechanical performance and is made for high-pressure working conditions, as the manufacturing method can be different in some producing progress.

Standards for Seamless Pipes for the High-Pressure Cylinders Tubing

• GB 18248 —— Seamless steel tubes for gas cylinder
• GB 28884 —— Seamless steel tubes for large volume gas cylinder
• ASTM A519 Standard —— Specification for Seamless Carbon and Alloy Steel Mechanical Tubing
• JIS G3429 —— Seamless steel tubes for high pressure gas cylinder

Standards JIS G3429 standard is typically applicable for gas cylinder steel tubing. We can manufacture the following grade of seamless steel pipe for gas cylinders: 37Mn, 34Mn2V, 30CrMo, 35CrMo, STH11, STH12, STH21, STH22, or anything else. Manufacturing Technology We adopt hot rolling (hot expanding) or cold rolling (cold drawing) to produce gas cylinder steel replacements.

• Q/TGGB31 —— (TPCO Enterprise standard) Seamless steel tubes for large volume gas cylinder
• BS EN ISO 11120 Gas cylinders —— Refillable seamless steel tubes for compressed gas transport, of water capacity between 150L and 3000L – Design construction and testing

Main Products and Applications

Available Size Range

Hot Finished Seamless Steel Tube and Pipe for Large Volume Gas Cylinder

We use 37Mn, 34Mn2V, 35CrMo, and other grades of steel to produce gas cylinder steel tubes. The basic length of a seamless steel pipe for a gas cylinder is between 4000mm to 12000mm. Winsteel is also capable to provide steel pipes longer than 12000mm or shorter than 4000 mm but isn’t quite shorter than 3000 millimeters.

This should be marked out in the contract after negotiated by the two parties. The number of steel tubes shorter than 4000 mm should not exceed five percent of your total number of delivered seamless steel pipes for the gas cylinder. The two end surfaces should be perpendicular to the steel pipe axis. The cutting burrs should be taken off.

Advantage of seamless pipes for the high-pressure cylinders tube:

• Compact Austenitic structure
• Size precision with a fine outer diameter and wall thickness,
• Smooth surface
• Larger capacity and higher working pressure
• Light and lower cost

Supply Performance of TPCO
