Heat resistant stainless steel pipe
Stainless Pipes and tubes
Stainless Pipes and tubes 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.

Seamless stainless steel pipe

It is the resistance of air, steam, water and other weak corrosive media and acid, alkali, salt and other chemical etching medium corrosion of steel pipes. Also known as acid - resistant stainless steel.

Stainless steel pipes is safe and reliable, environmental health, affordable, and the thin wall of the pipe as well as new and reliable, the successful development of a simple and convenient connection method, which make it more irreplaceable advantages. It will be more and more engineering use and become increasingly popular, and prospects.

Stainless steel seamless pipe features:
First, the thicker the wall thickness of the product, it is more economical and practical, the wall thickness of the thinner, its processing costs will rise substantially;

Secondly, the process of the product determines its limitations, the low accuracy of the general seamless tube: non-uniform wall thickness, the appearance of low brightness tube, the high cost of fixed length, and within the appearance of pitting, black spots difficult to remove; Third, the detection and plastic must be offline processing. So it is at high pressure, high strength, the mechanical structure timber reflects its superiority.

The corrosion resistance of stainless steel seamless pipe depends on the alloying elements contained in the steel. Chromium is the basic elements of corrosion resistance for the stainless steel, about 12% the amount of chromium in the steel, chromium and oxygen role in the corrosive medium, the steel surface to form a thin oxide film (passive film) matrix can prevent the steel from further corrosion. Removing chromium, stainless steel seamless pipe commonly used alloying elements there are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of the various uses of the organization and performance of stainless steel.
