Stainless Steel Tube

Petropipe is known supplier of Stainless Steel tube

Petropipe is a known supplier of SS 304 / 304L / 304H / 304LN / 304N PIPES AND TUBES, which is the most common stainless steel. Stainless steel tubes are often used in applications that require rigid materials for potable water conveyance. Manufacturers select stainless steel because certain man-made materials have unwanted or unknown exposure effects while stainless steel has many desirable qualities for maintaining clean water. Steel tubes can also be used for structural support in buildings and vehicles. The terms “tube” and “pipe” are generally interchangeable, although technically, “tube” implies heightened engineering qualities. Tubes are generally manufactured based on standardized sizes. As a prominent stainless steel tube supplier, we are ready to deliver products on time.

Manufacturing Steel Tubes

There are three main methods of manufacturing tubing that lend their names to tubing classifications. 

  • Seamless steel tubes are produced through extrusion. Extruded tubes can be formed in a hot or cold process. Long sections of steel bar are forced through a die that blocks out the intended shape of the tube.
  • Seamless Steel Tubes are 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 pipe. The hollow pipe is then extruded through a die & mandrel combination to reduce the outside diameter and to expand the inside diameter.
  • As-welded or electric resistant welded (ERW) Tubes: This method involves passing a rolled sheet of steel through two weld rollers. The weld rollers have a groove around their circumference, through which the steel roll passes. There is a contact at the roll seam that transmits electricity at a high enough current to weld the seam closed. The resulting weld is very small.

Stainless Steel Tube Applications

Hydrocarbon Industries & Refineries, Oil & Gas Exploration & Drilling, Oil & Gas Transportation and Air and Hydraulic cylinders, Bearings, Boilers, Automobiles, Heat exchangers, Food industry, Chemical industry, and Petroleum industry. SS 304N Seamless Pipes is essentially non-magnetic and becomes slightly magnetic when cold worked. SS 304N Welded Tubes is often used in the following applications: Valves, Cooling coils, Oil well filter screens, Evaporators, Pressure vessels and more. 304 SS Round Seamless Pipes and Tubes Stockholders, 304L Square Welded Pipes, SS 304H ERW Rectangular Tubes Traders, AISI 304 Hollow Pipes, SS 304LN EFW Oval Pipes, 304N Mirror Polished Tubing Distributors
