Seamless Steel Pipe

SCHEDULE 140

The main difference seen in seamless vs welded pipe is their method of construction. For instance a schedule 40 seamless stainless steel pipe is extruded and drawn from a billet, on the other hand, a welded stainless steel pipe is produced from a strip which is first roll-formed, followed by a welding process that is carried out to produce a pipe. Although in terms of its costing, a welded tube is significantly less expensive in comparison to a schedule 40 seamless carbon steel pipe. Moreover, a welded pipe is readily available in continuous, long lengths. However, this being said, any Seamless Steel Pipe Manufacturer can attest to the fact that the working pressure of a welded pipe would be 20% lesser in compared to a similar alloy grade seamless pipe. Different piping systems have different requirements.
For instance, there are some applications like marine engineering that would require a strong corrosion resistant variety of Schedule 40 Smls Pipe Price, wherein buyers would prefer using grade 316 stainless steel. On the other hand, if a carbon or alloy steel is to be used in any application, the buyer could get a galvanized seamless steel pipe. Galvanization is a process performed on astm a53 schedule 40 seamless steel pipe, wherein the steel pipes are coated with a thicker layer of zinc, which in turn aids in corrosion resistance. The seamless black steel pipe schedule 40 produced under specification ASTM A53, are required to adhere to the chemical as well as mechanical properties of the standard by undergoing tests such as the tension, bend, and flattening tests.

Seamless Steel Pipe Manufacturing Process

We use Drawn on Mandrel method, also known as the Cold Drawn Process, to manufacture our seamless tubes to provide smooth interior and exterior finish and dimensional tolerance. The tubes are Heat Treated to achieve the required mechanical characteristics. To put it clearly, they are stress relieved, normalized, and tempered as per grade requirements and your specifications. Then to achieve the required accurate straightness in tubes, we use multiple roll straightening equipment.

We perform rigorous quality checks to ensure that the products delivered to you are of the highest quality. In addition to this, we follow best packing practices, including using a Special 4-Layer Packaging for exports, to make sure that the materials reach their destination in excellent condition.

 

Industrial Uses Of Schedule 40 Seamless Steel Pipe

Cryogenic pressure vessels, pressure piping and other such piping systems typically utilize seamless tubes. In addition to this, they are also used in high-pressure equipment, boilers, heat exchanger tubes, air preheaters, steam release pipes, air cooler tubes, steam trap piping and more.Industries such as shipbuilding, power plants, refineries, chemical factories, steel plants and fertilizer industries use seamless steel pipes for a variety of processes.

Seamless Or ERW Stainless Steel Pipes Identification

To identify that a pipe supplied is seamless or ERW, Simply read the stencil on the side of the pipe

  • If it is ASTM A53, Type S means seamless.
  • Type F is furnace but welded,
  • Type E is Electrical resist welded.
  • Thats how. It is the easiest way to identify wether pipe is seamless or ERW.
