Advantages, disadvantages and development direction of spiral welded pipe
Spiral welded pipe (ssaw): It is made by rolling low-carbon carbon structural steel or low alloy structural steel strip into a tube blank according to a certain helical angle (called forming angle), and then welding the pipe seam. It can be made with narrower strip steel produces large diameter s...Read more -
ADVANTAGES OF STAINLESS STEEL PIPES
ADVANTAGES OF STAINLESS STEEL PIPES All stainless steels must contain at least 10% chromium. The strength and durability of metal. Mainly due to the chromium content. It also includes varying amounts of carbon, manganese, and silicon. In some types, nickel and molybdenum are added depending on th...Read more -

CORROSION OF STAINLESS STEEL PRODUCTS
CORROSION OF STAINLESS STEEL PRODUCTS Stainless steel is an alloy of iron containing at least 10.5% chromium. This chromium allows the formation of a very thin oxide layer on the metal surface, also known as the “passive layer” and gives stainless steel its distinctive shine. Passive ...Read more
