Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
16Mn steel weldability is very good, general use TIG with J50 welding wire, hand arc welding with J506, J507 and other welding rod
Q:How to descaling galvanized steel pipe?
Galvanized steel tubes will not rust in principle.... Batch rust with weak acid water immersion, individual can use steel wire brush brush on it.
Q:What does the diameter of a steel pipe project mean?
Nominal surface meaning can be understood as a public address. It's as if everyone agreed to call something as a "devil", and he was the devil.Don't be confused by the numbers behind the nominal diameter. For example, DN50, this 50 is really close to the outer diameter or inside diameter of the steel tube, but DN50 is only a general model of the caliber of the national standard.
Q:What is the difference between steel pipe and round steel?
The middle of the steel pipe is hollow, and the round steel is solid. When compared with the solid steel such as round steel, the steel tube has the same flexural strength and torsion strengthLight weight, is an economic section of steel, widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.
Q:What's wrong with the 3PP anticorrosive steel tube?
PP and PE are similar in processability, and the 3PE coating can be used to produce 3PP coatings without the need for a special 3PP coating line. However, the difference between PP and PE materials makes the 3PP and 3PE coatings show different properties, which can be applied to different environments. The advantages of 3PP coating on some properties make it possible to play an important role in the field of 3PE coating. Therefore, many foreign pipeline projects use 3PP anticorrosive coating.
Q:What's the gate number of the precision steel pipe?
This kind of steel tube and ordinary hot-rolled seamless steel pipe and cold drawn seamless steel tube in the outer surface is different from the outer surface, and the diameter of the smooth finish of precision steel tube, stainless steel color and the same, inside and outside surface due to manufacturing reasons with a layer of oil.
Q:What is the diameter of the steel tube DN20?
The symbol is DN, the unit is mm, but omitted to write. Also available in English in.
Q:How much is 4 inches steel tube MM?
The standard wall thickness is 4mm, so the outer diameter is 114mm.
Q:What is the outer diameter of the steel tube?
The diameter of a steel pipe refers to the diameter of the steel pipe. The specifications of the steel tube is normal with diameter (diameter and thickness) said, for example 100MM outer diameter and wall thickness of 5MM tube is marked with 100*5.
Q:Steel pipe is particularly long, how to clean the inner wall of the pipe so that it can be thoroughly cleaned
The urban water supply pipeline cleaning is a very necessary work, it can not only improve the transmission efficiency of pipeline to reduce energy consumption, but also to clear the pipeline dirt, remove two pollution, improve water quality, protect the people's physical and mental health.
