1、Structure of Stainless Steel Welded Pipe ASTM A358/A312/A778 Description:

    Stainless steel welded pipe is actually a cover term, covering a wide range of alloy and making them suitable for different attributes that are used in a very wide and large numbers of different industries. Stainless steel pipe is resistant to erosion, highly flexible, powerful, easy to use, and can be done in distinct approaches, which means that more and more stainless steel was used as a construction material for large-scale, high impact buildings. It can be molded, rolling, and it can create amazing shapes to make it perfect, It is used as experimental buildings, The use of steel pipe welding of large stainless steel covers other examples.

Q:What's the difference between steel pipe and pipe fittings?
Pipe fittings: parts that connect pipes to pipes. According to the connection method can be divided into socket type pipe fittings, threaded fittings, flange pipe fittings and welding pipe fittings four kinds. Multipurpose; made of the same material as pipes. Elbow (elbow), flange, three pipe and four pipe (crosshead) and reducer (reducer) etc.. Elbow for pipeline corner; flange for the pipe and pipe interconnected parts, connected to the pipe end, three pipe for three pipe collection; four pipe for four tubes together place; for two pipes of different diameters connected to different diameter pipe.
Q:How long are the seamless tubes? Are they six meters long?
6 meters of a root in general need to be customized, seamless tubes are mostly seven meters above the variable foot
Q:Can galvanized pipe be welded with seamless steel tube? What should I do to connect?
Processing method is very simple, I suggest you add blue disk connection, you can not use welding ~ ~ ~!The gas pipe is the best galvanized pipe, mainly play a role in anti-corrosion ~ ~ ~ ~ if you must use seamless connection can.When welding, can open a certain groove, use galvanized material electrode, but the premise is must be welded with seamless tube firmly.
Q:Could you tell me what difference between SC galvanized steel pipe and MT wire pipe?
Hot galvanized steel pipe galvanized color silver plated SC.MT wire pipe galvanized color silver plated or silver plated cold yellow fever.
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 is DN50 for welded pipe?
Refers to the use of welded steel pipe made of DN50 steel pipe, refers to the inside diameter is 50mm, the market of common DN50 pipe also refers to the 2 inch pipe, standard pipe: 3.5mm thickness, pipe diameter 60mm, the weight of 4.88kg/m theory.
Q:How are steel tubes represented?
If it is seamless steel pipe, welded steel pipe, the method of expression is: nominal diameter refers to the outer diameter (diameter * wall thickness). The unit is mm. [for example, seamless steel tubes of phi 32 * 3. It means that the nominal diameter (outside diameter) is seamless steel pipe of phi 32mm and wall thickness 3mm.
Q:Seamless steel tube DN15 specification phi 18*3 what do you mean?
Seamless steel pipe DN15 specification phi 18*3 refers to 3 outer diameter of 18mm B type DN15 seamless steel tube.
Q:What's the use of steel pipe?
(processing workshop of Tianjin steel pipe company as a result of the steel pipe truss structure, the actual steel saving up to 42.9%), with a steel pipe manufacturing highway bridge can not only save steel, simplify the construction, but also can greatly reduce the coated area, saving investment and maintenance costs.
Q:What does "steel pipe SC" mean?
SC (run in welded steel duitconSC is the line laying mode GB letter of wire is worn steel pipe laying (welded steel pipe, low pressure fluid) SC70 said the conductor by low pressure fluid DN70 welded steel pipe as protection pipe laying, DN70 said the nominal pipe diameter is 70mm, the nominal pipe diameter is 70mm (a series of values, the actual diameter slightly different).
