Q:Classification, advantages and disadvantages of stainless steel welding
The utility model has the advantages of universal use and easy operation, and is mainly regulated by people, and the welding seam material is an electric welding strip. Manual welding can weld almost all of the material, even outdoors, so it has good adaptability and is usually powered by direct current.Welding, either titanium type electrode, can also be sealed. The titanium electrode is easy to weld, the welding seam is beautiful, and the welding slag is easy to remove. But the drawback is that if you do not use it for a long time, you must bake it again to prevent moisture accumulation.
Q:Stainless steel pipe is mainly used in what areas?
Stainless steel pipe is a kind of hollow long strip round steel, mainly used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts. In addition, the bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Q:Are stainless steel tubes and galvanized steel tubes the same?
Stainless steel management theory, the whole is not rusty, from the table to the material is stainless steel, no surface and internal.
Q:Why is the outer diameter of 1 inch galvanized pipe 33.7? And the outer diameter of one inch stainless steel pipe is 25.4
Some 25.4 such outer threads, is the imperial Whitworth Thread and American Standard unified thread, single head wire estimate.
Q:304 stainless steel will rust it?

Specifications for seamless steel tubes are expressed in millimeters of outer diameter * wall thickness. Seamless steel pipe, hot-rolled and cold-rolled (DIAL) seamless steel pipe two categories.Hot rolled seamless steel tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..
Q:Stainless steel and stainless steel pipe inside and outside polishing off, what is the difference?
The inside and outside polishing tubes are polished by the surface of the polished material, and they look like bright ones, just like the mirror surface. Mainly used in viscous liquid and gas moving equipment, such as printing and dyeing, pulp and other industries
Q:Are stainless steel pipelines buried in need of corrosion protection?
Pipeline buried environment factors: underground laying requirements of 3, one is corrosion protection, two is elevation, slope, and three is density. If it is electrochemical reaction, the design should have technical instructions or preventive measures.
