Stainless Steel is one of the most popular and widely utilized metals for the production of pipes, because of its varied chemical composition and properties. Stainless steel pipes are offered in a variety of grades, materials, and requirements to meet all industrial applications. In contrast, seamless tubing has no welds and is uniform throughout the tube’s cross section, avoiding any dangers that could be present at the weld seams. These dangers include corrosion, weld contamination, off-seam welds, stress concentrators in high-pressure applications, and stress concentrators.
A solid billet is drawn through a piercing rod to create the seamless pipes, which are hollow and spherical. They are frequently used in high-pressure applications such as oil and gas transportation, boilers, cars, hydrocarbon production and refineries, air and hydraulic cylinders, oil and gas extraction and drilling, bearings, etc. Due to their complicated production process and the oligopolistic market, seamless pipes are more expensive per ton than other types of pipes. In order to retain high performance, SS 316 Seamless Pipes are put through a number of tests, including ultrasonic welding testing, hydro-testing, straightness evaluation, micrometre inspection, and ring gouge test.
Seamless stainless steel coil tubing is the material of choice for numerous applications, harsh environments, and crucial industries because it has a minimal risk of impurities, strong corrosion resistance, and inexpensive installation costs. It is frequently employed, for instance, in chemical process and instrumentation applications such as fluid and gas transfer, flow measurement and sensing, and steam and heat trace bundles. Control lines, chemical injection, and subsea valves are all used in the oil and gas business. It is also perfect for gas chromatography (GC) and high-performance liquid chromatography equipment since small-diameter seamless stainless-steel tubing can resist pressures beyond 30,000 psi for essential applications.
The Benefits of Seamless Stainless Steel Pipe
- Seamless pipes are more practical and cheaper the thicker their walls are, but the more expensive their processing will be the thinner their walls are.
- The seamless pipe’s performance limitations are based on the manufacturing process. Uneven wall thickness, low brightness on the inside and outside of the pipe, low precision, high cost of fixed length, and pits and black spots on the inside and exterior of the pipe that are difficult to remove are all common characteristics of seamless steel pipes.
- Seamless pipes must undergo offline processing for shape and inspection. Because of this, it demonstrates its supremacy in terms of mechanical structural materials and high pressure, high strength, and materials.
Applications for seamless coil tubing that are more recent include the transfer of hydrogen for material handling applications, the resupply of firefighter air, and the transfer of compressed natural gas (CNG) for vehicle refuelling (FARS). Because seamless tubing only needs one fitting, businesses may cut installation time, labour costs, and expenses.
