Overview

Stainless steel tubes have also been developed for many years and Stainless Steel Tube for Power Plant is widely used. It is produced by cold drawing and has seamless walls. The surface is ground but not polished, so that it is burr-free but not smooth. The tube wall thickness is generally thicker and you have to process it to shape it. Due to its excellent properties, our Stainless Steel Tube for Power Plant is commonly used in power plants, machining, construction work and many other applications.

Stainless Steel Tube for Power Plant has a rough and thick wall and a high pressure resistance, and is mostly used to meet high pressure, high strength and mechanical structure products. In addition, compared to galvanised steel tubes, stainless steel tubes are more superior. In particular, the wall thickness of only 0.6 ~ 1.2mm thin-walled stainless steel pipe in the drinking water system, water supply system more hygienic. With safe and reliable, health and environmental protection, economic and applicable characteristics.

Mechanical Properties

And other materials would be listed in other products' introduction.

Hardness Requirements:

The material shall conform to the hardness requirements given in Table 4. Brinell, Vickers, or Rockwell hardness tests shall be made on specimens from two tubes from each lot.

Flattening Test-One flattening test shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot.

Flaring Test-One flaring test shall be made on specimens from each end of one finished tube, not the one used for the flattening test, from each lot.

Mechanical property requirements do not apply to tubing smaller than 1⁄8 in. [3.2 mm] in inside diameter or thinner than 0.015 in. [0.4 mm] in thickness.

Each tube shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the option of the manufacturer unless otherwise specified in the purchase order.

Tubes, when inserted in a boiler or tube sheet, shall stand expanding and beading without showing cracks or flaws. Superheater tubes when properly manipulated shall stand all forging, welding, and bending operations necessary for application without developing defects.
