What is ERW Pipe
Welded steel pipe, also known as ERW pipe, is a steel pipe made of steel plate or strip after crimping and forming, with a general fixed length of 6 meters. ERW pipe has simple production process, high production efficiency, a variety of specifications, less equipment investment, but its general strength is lower than the seamless steel pipe.



General ERW pipe: General ERW pipe is used to transport low-pressure fluid. It is made of Q195A, Q215A and Q235A steel. It can also be made of other mild steel that is easy to weld. Water pressure, bending, flattening and other tests shall be carried out for steel pipes, with certain requirements for surface quality. Generally, the delivery length is usually 4-10m, and the delivery is required to be fixed length (or multiple length).



The specification of the welded pipe is indicated by the nominal diameter (mm or inch). The nominal diameter of the welded pipe is different from the actual one. According to the specified wall thickness, there are two types of welded pipe: ordinary steel pipe and thickened steel pipe. According to the form of pipe, the steel pipe is divided into two types: with thread and without thread.



Galvanized steel pipe: in order to improve the corrosion resistance of steel pipe, the general steel pipe (clarion) is galvanized.

Galvanized steel pipe is divided into two types: hot-dip galvanizing and electric-dip galvanizing. The thickness of the hot-dip galvanizing layer makes the cost of electro galvanizing low.

What is Galvanized Steel Pipe
What is galvanized steel pipe? Galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, exploration machinery and other manufacturing industries.



Welded steel pipe with hot dip or electro-galvanized coating on the surface of galvanized steel pipe. Galvanizing can increase the corrosion resistance of steel pipe and prolong its service life.



The galvanized pipe is widely used, not only as the pipeline for water delivery, gas, oil and other general low-pressure fluid, but also used as the oil well pipe in the petroleum industry, especially in the offshore oil field, the oil heater, condensate cooler, coal distillate wash oil exchanger pipe for chemical coking equipment, as well as the trestle pipe pile, mining tunnel supporting frame tube, etc.



Welded joint



1. Galvanized steel pipe is not in a straight line after the pipe mouth is connected and there is an inclined opening in the steel pipe. It is recommended to cut off a small section of the steel pipe end before processing.



2. After the butt joint of the pipe mouth of galvanized steel pipe, the joint of two pipes is not strict, resulting in uneven thickness of the welded junction; And the ellipse of the pipe mouth is caused by the collision of the steel pipe due to its own reasons or transportation. It is recommended to cut off a small section of the pipe end before processing.



3. Sand holes appear at the mouth of galvanized steel pipe after the pipe mouth is butt joint.



4. Welding is caused by technical reasons.



5.There is a zinc tumor at the pipe mouth, which causes welding difficulties and sand-hole problems. Simple removal treatment of zinc tumor is carried out for large and excessive zinc tumor.

What is Galvanized Pipe?
What is a galvanized pipe? Galvanized pipe is to make molten metal and iron matrix reaction to produce an alloy layer, so that the matrix and coating of the combination of the two.



Hot-dip galvanizing involves pickling the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, the steel pipe is cleaned through the aqueous solution of ammonium chloride or zinc chloride or the aqueous solution of ammonium chloride and zinc chloride mixed, and then send it to the hot-dip plating bath. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.



Galvanizing copper wire plating of galvanized pipe is the same as continuous plating, but the equipment of plating is different. The plating bath for wire is designed with its long and thin strip characteristics, and its body is long, wide and shallow. During electroplating, the iron wire is threaded through the holes, spread out in a zigzag shape at the liquid level and maintain the space between each other.



However, the galvanized pipe is different from the iron wire, with its unique features, and the groove equipment is more complex. The tank is composed of upper part and lower part. The upper part is a plating tank and the lower part is a solution circulation storage tank, forming an upper narrow and lower wide, trapezoidal tank. In the plating tank, there is a channel for galvanizing pipe electroplating operation. At the bottom of the tank, there are two through holes connected with the storage tank at the lower part, and a plating solution circulation and reuse system is formed with the lower liquid pump.



Therefore, the galvanized pipe is dynamic like the iron wire plating, and the plating solution of galvanized pipe is also dynamic unlike the iron wire plating.
