1. Power supply with vertical external characteristics is adopted, and the positive polarity is adopted for direct current (the welding wire is connected to the negative electrode).2. Generally suitable for the welding of thin plates below 6mm, with the characteristics of beautiful weld shape and sm
Straight seam welded pipeStraight seam welded pipe is made of steel plate or steel strip after bending forming, and then through welding. Divided into the form of the weld seam welded pipe and spiral welded pipe by the welding forming method. According to the application, the straight seam weld pipe
Spiral pipe, also known as spiral steel pipe (SSAW), is a kind of tubular steel made of low carbon steel or low alloy steel through spiral welding process. Spiral pipe has the characteristics of high strength, good bearing capacity and excellent welding performance, so it has a wide range of applica
Commonly used welded steel pipes are divided into the following three types according to the welding process used in their production. ① Continuous furnace welding (forge welding) steel pipe: It is characterized by high production efficiency and low production cost, but the metallurgical combination
What is API 5L Line Pipe?In this article you’ll learn about API 5L Line pipes. The specification of the API 5L covers seamless and welded pipes for transporting oil, gas, water in the oil & gas and petrochemical industries.API introduced by the American Petroleum Institute (API) API-5L standard earl
Cylinder steel or billet are often used to manufacture seamless steel pipe. The procedure begins with heating a piece of steel. Unless it gets the expected shape, size, the billet is rolled out thoroughly.Seamless steel pipes are known for bearing higher pressure compared to welded steel pipes. Nowa
One of the most widely-used products in various industries is the seamless pipe. This material can be manufactured in many different ways, depending on the usage. Generally, seamless pipes are used to transfer fluids from one point, or location, to another. Knowing more about the functions of seamle
1. Argon arc welding is a welding technique that uses argon as a shielding gas. Also called argon gas shielded welding. It is to pass argon shielding gas around the arc welding to isolate the air from the welding area to prevent oxidation of the welding area. The argon arc welding technology is base
1. Welded steel pipes for low-pressure fluid transportation are used to transport water, gas, steam, compressed air, etc.; structural welded steel pipes can be used to manufacture scaffolding, trusses, towers, playgrounds, railings, etc.;2. Special-shaped tubes for steel doors and steel windows are
