Welded steel pipes are often used in various engineering projects. What are its advantages? Today we will introduce them in detail.

Welded pipe is made by cold forming flat strips, sheets, or plates into a round or circular shape by a roller or plate bending machine. The pipe is then welded with or without filler material using a high-energy source. Welded pipes can be produced in large sizes without any size restriction. Welded pipes are normally used for the transportation of water, oil, or gases in large quantities.

Welded steel pipes are always available in plenty because of their lower production cost and raw materials availability. It is, therefore, one of the most widely used metals in the world. Its application in different industries and the manufacture of numerous products. Examples of ASTM or API 5L welded steel pipes include SSAW pipe, ERW steel pipe, and LSAW pipe.

• Welded steel pipes are more enticing in terms of cost compared to the seamless options. These pipes are often more available when you need them compared to seamless ones. The seamless ones will take longer because of their lead time so they are not always as available as the welded steel pipe.

• The thickness of welded pipes is going to be more consistent compared to the seamless options.

• The surface of the welded steel pipe is able to be checked out before they are released for sale to ensure they are going to work out for your needs. This is something that is not available with the seamless options.

• Welded pipes are typically more cost-effective than their seamless equivalents.

• Welded pipes are usually more readily available than seamless. The longer lead time required for seamless pipes can not only make timing problematic but also allows more time for the price of the materials to fluctuate.

• The wall thickness of welded pipes is generally more consistent than that of seamless pipes.

• The internal surface of welded tubes can be checked before manufacturing, which isn’t possible with seamless.

Many people confuse the ERW pipe with seamless steel because it does not use fusion metals, the weld seam is not always visible, and you cannot feel it. On the contrary, a Double Submerged Arc Weld (DSAW) leaves evident traces of weld beads, which can be eliminated using different processes depending on the application method.

Cangzhou Shenlong Pipe Manufacturing Co., Ltd. cooperates with Baosteel and Baogang to produce large-caliber seamless steel pipe, straight-seam welded pipe, spiral steel pipe, and pipe fittings. The products comply with API, ASTM, DIN, BS, and JIS standards, and can accept SGS, BV, and other inspections. The products are used in oil, natural gas, bridge, water conservancy, and other large-scale projects, which are worthy of trust.
