All You Need to Know About Seamless and ERW Stainless Steel Pipe?

Electric Resistance Welding pipes and tubes are commonly used in a number of sectors, including engineering, construction, line pipes, scaffolding, etc. Some of the typical applications of ERW pipes can be seen in the agriculture and irrigation sector, in particular in sewage systems, water lines and industrial water lines, deep tube wells, plant pipes, etc. They are also commonly used in gas pipelines, especially in the production of natural gas, LPG and other non-toxic gas pipelines.

For the manufacture of ERW pipes, the metal is rolled and welded longitudinally. If you look at the manufacturing method of seamless pipes, they are produced by extruding the metal to the required length. It ensures the seamless pipes do not have cross-section joints across their length. ERW pipes, on the other side, have welded joints along their cross-section.

The seamless pipes are round and hollow, and are produced by drawing a solid billet through a piercing rod. They are commonly used in high-pressure applications such as Oil & Gas Transportation, Boilers, Automobile, Hydrocarbon Manufacturing & Refineries, Air and Hydraulic Cylinders, Oil & Gas Extraction & Drilling, Bearings, etc. Seamless pipes have a higher price per ton due to their complex manufacturing process and the oligopolistic environment.

The ERW pipes are produced from Strip or Coil. Such pipes are mainly used in applications under low to medium pressure, such as transport of water and gas. If you are searching for high-quality ERW pipes, you need to consider one of the leading manufacturers of ERW Stainless Steel Pipes.

Silver tubes are one of the leading stockiest, exporters and manufactures of the product Stainless Steel 304 Seamless Pipes. These pipes are made up of meeting all of the national and international standards.

Special features of superior quality ERW pipes and tubes

  • High strength corrosion resistance
  • High malleability
  • Superior strength
  • Durable and sturdy

SS 316 Seamless Pipes are processed through various tests, including ultrasonic welding testing, hydro-testing, straightness evaluation, micrometer inspection and ring gouge test to maintain good efficiency. In short, ERW pipes are cost-effective pipes with better dimensional tolerances and less weight. ERW pipes are found in different areas. In addition to oil, water and gas conveyance, ERW pipes are commonly utilized in the agricultural and automobile industries.   Owing to their versatile usability and durability, ERW pipes are commonly used for drinking water, thermal power, in collieries for water extraction, used as hand pumps for boring wells, as protection cable for the telecommunications field. Some of the popular application areas of ERW pipes include:

  • Engineering and structural purposes: Fencing, line pipes, scaffolding
  • Automobiles Sector (Tremendous boost in usage in recent years)
  • Water and gas conveyance, oil country tubular
  • Agriculture Sector
  • Collieries for extraction of Water, Thermal Powers
  • Hand pumps for deep boring wells, Drinking water in housings
  • Strong and complete protection of cables by Telecom Department


If you are looking for ERW Pipe Dealers, Seamless Pipe supplier, or any Steel Pipe Souring, you should choose a quality conscious manufacturer that manufactures high-quality pipes in India. Chosen manufacturers must be able to produce high-quality pipes in distinct specifications, sizes, and grades to meet the needs of sectors like Agriculture, Public Health, Oil and Gas, Housing, Irrigation, and Engineering etc.
