Welded steel pipe, also known as welded pipe, is made of steel plate  or strip steel after crimping. The production process of welded steel pipe is simple, the production efficiency is higher, the cost is more lower, the product variety is getting richer, but the general strength is lower than seamless steel pipe.
Welded steel pipe according to the welding process is divided into furnace welded pipe, electric welding (resistance welding) pipe and automatic arc welding pipe, according to the welding form is divided into straight seam welded pipe and spiral welded pipe, according to the end shape is divided into round welded pipe and special-shaped (square, flat, etc.) welded pipe. According to usage, it is divided into general welded pipe, galvanized welded pipe, oxygen blown welded pipe, wire bushings, metric welded pipe, roller pipe, deep well pump pipe, automobile pipe, transformer pipe, thin-wall welded pipe, special-shaped welded pipe and spiral welded pipe. Because of the different welding methods, there are different methods of producing welded steel tubes. The application of welded pipe is mainly used in boilers, automobiles, ships, light construction structure of doors and Windows steel, furniture, various agricultural machinery, scaffolding, wire pipe, high-rise shelves, containers and so on.

Galvanized pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the in the hot dip bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made of low carbon structural steel or low alloy structural steel strip rolled into a pipe billet at a certain angle of the spiral line (called the forming angle) and then the pipe seam is welded together, which can produce large diameter steel pipes from narrower strips of steel.

ASTM A656 steel plate is a high-strength low-alloy steel used in structural applications. In structural applications, light weight and good formability are essential. ASME A656 steel plates are manufactured in different grades of 50, 60, 70 and 80 to the specified yield point.

ASTM A202 grade is divided into: A, B, boiler vessel plate is mainly used for welding boilers and other pressure vessels. There are two grades of ASTM A202 boiler vessel steel: Grade A and Grade B. The thickness of ASTM A202 boiler vessel plates is limited to 2 inches.

EN10025-2 steel plate is a low-alloy high-strength structural steel, which is made of carbon structural steel by adding a small amount of alloying elements.

DIN 17100 ST37 is a carbon structural steel widely used in construction, machinery and manufacturing industries. It has good mechanical properties and can be used to manufacture various mechanical parts.

ASTM A514 steel is available in several grades: A, B, C, E, F, H, J, K, M, P, Q, S, and T, all of which have the same mechanical properties. ASTM A514 steel plates are conventionally quenched and tempered steel. ASTM A514 steel plate is known for its high yield strength, weldability and toughness. ASTM A514 steel is a special high-strength steel, mainly used as building structural steel.
