Sincerely hope we become long-term partners - Steel pipe & Fittings:

Stainless Pipes and tubes

Stainless Pipes are made from more than 20 steel grades of various corrosion resistance and are intended for application in conditions of a wide range of corrosion environments and temperatures in heat exchanger.

• History of stainless steel
• The main elements in stainless steel
• Types of stainless steel
• Comparision number between China and International
• ANSI Standards Stainless Steel Pipe Specs
• ASTM A511/A511M Standard Specification

Applications

Heat Exchanger Tubes (U-bend or U-shape) >>

This specification covers minimum-wall-thickness, seamless cold-drawn carbon steel tubes including bending into the from of u-tubes, if specified, for use in tubular feedwater heaters.

Welded steel pipes >>

HYST QCCO China Steel produce an extensive selection of welded pipe including Electronic Resistance Welded (ERW), Electronic Fusion Welded (EFW), and Double Submerged Arc Welded (DSAW) carbon steel pipe along with their respective flanges and fittings.

Why Welding steel tube?

Range of Applications >>

Steel pipe are ubiquitous and can be found underground and within residential walls, laboratories, and commercial and industrial structures.
Seamless steel pipes are produced using an extrusion mold. Welded steel pipes are produced by rolling a sheet of steel into a tube and welding the seam. Seamless steel pipes are less expensive. The third method is casting. Molten steel is poured into a casting mold.
