Jan 28, 2019 · Straight seam steel pipe Straight seam steel pipe is a steel pipe whose weld is parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded steel pipe, welded thin walled pipe, transformer cooling oil pipe and so on. Straight seam welded pipe has simple production process, high production efficiency

Commonly, it is different in the properties of the two types of pipes. The welding process of spiral tube, straight seam steel pipe welding methods are varied from the previous process. So the probability of the presence of welding defects also greatly improved. The straight seam pipe will inevitably be a lot of T weld.
SAW steel pipes is short of Submerged Arc Welding Steel Pipe, which it is a use of submerged arc soldering process to manufacture steel, the process produces a very high current density, the flux layer to prevent the rapid loss of heat, and concentrated in the welding region.
Welded Pipe American Piping distributes an extensive selection of welded pipe, including Electric Resistance Welded (ERW) and Double Submerged Arc Welded (DSAW) carbon steel pipe — along with their respective flanges and fittings. We also carry A139 — Grade B, A252 Grades 2 & 3 spiral weld pipe, and A691 chrome moly pipe.
Welded steel pipe is also known as welded pipe, is the steel pipe made of steel plate or steel strip after curling forming, and the general length of 6 meters. Divided into
Straight Seam Steel Casing Pipe Straight seam steel casing pipe is so called because the pipe is rolled from strip and formed with one longitudinal weld. This straight seam steel casing pipe is generally manufactured by an Electric Weld or a DSAW type of manufacture.
Seamless Steel Pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. Billets are
Utilizes the "JCO" process to bend and form the crimped steel plate into a steel pipe. Interior welding machine The interior longitudinal seam of the pipe is welded from the inside by fixing 4 welding heads while moving pipe and using submerged arc welding process. End facing machine
This is a pipe cap. As the name says, you use it to cap the pipe. If you have a pipe or nozzle or something similar, you can butt it up and weld it and cap the pipe, so a pipe cap. In summary, butt weld pipe fitting is available in carbon steel, in stainless steel, and nickel alloy.

At the first, the spiral welded steel pipe meets to high strength comparing with longitudinal welded pipe. The second, according to the test of relevant research institutes in the United States, although the spiral welded pipe and the straight welded pipe(ERW pipe) are in the same grade, the spiral welded steel pipe has higher impact toughness.
The most common pipe fitting is a stainless steel pipe tee or specifically a straight pipe tee. Tees have two outlets at 90 degrees from the main flow and are used to combine or split fluid or gas flow. Tees connect and combine pipe systems or they can connect various size pipes together with reducing tees.
On the contrary, welded steel pipe don’t have these limitations, sizes available from 1 1/2 inch 48.3mm to 100 inch 2540 mm. 5. Cost and prices. Usually the seamless steel pipe cost is higher than welded steel pipes, because the raw material, manufacturing equipment and processes.
Pipes are sold by "nominal pipe size" in sizes from 1/8" to 72". The two most common types of pipes are welded pipe and seamless pipe. Both are available in carbon steel and stainless steel. Welded pipe is also called ERW (Electric Resistance Welded) pipe. Most common specification for welded carbon steel pipe
The steel for both seamless and welded pipe shall be made by one or more of the following processesopen hearth, electric furnace, or basic oxygen. The weld seam of electric resistance welded pipe in Grade B shall be heat treated after welding. Couplings, 2″ and smaller straight tapped, other sizes taper tapped. Thread Protection

Jul 26, 2019 · Straight seam welded steel pipe is a steel pipe made by hot rolled or cold rolled steel plate or steel strip. The pipe obtained by straight seam welding on the welding equipment is called straight seam welded pipe.
Types of Pipe Fittings Used in Piping. In this type of flange, the stub is butt welded to the pipe, whereas flange is freely moved over the stub end. It is basically flange part but covered under ASME B16.9 that is why it is considered as pipe fittings. And B16.28 which is standard for Wrought Steel Butt Welding Short Radius Elbows and
