ERW Pipe
  A pipe formed by Electric Resistance Welding or ERW having one vertical seam without addition of any metal called ERW pipes or tubes. It can be available in varied diameters and wall thickness. The sizes of pipes ERW pipes can range from 2 3/8 inch to 24 inch outer diameter and length can be over 100feet.
SAW Pipe - Roll Bending Pipe
  The welding part of the roll bending pipes is straight seam. The SAW(Submerged ARC Welding) method is applied, in which welding is done by ARC, occurred in between two poles between the base metal and the welding part. This makes the production of strong, large diameter, high grade pipes possible. The demand for roll bending pipes has particularly increased in petroleum and gas line pipes.
SAW Pipe - Spiral Pipe
  Spiral method makes possible to manufacture pipes with various outer diameters according to customer's demands since the welding part is spiral, which is utilized to manufacture pipes for water supply, basement of civil work, and steel pipe for construction principally
Seamless Pipe
  Seamless (SMLS) Steel Pipe is 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 tube. The seamless pipe is then finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 26 inch OD
Stainless Pipe
  Stainless steel pipe,from preexisting recognition focusing on particularities of surface, is now expanding its use into equip-
ment and piping for various kinds of chemical industry, high temperature and high pressure, nuclear energy, extremely low
temperature, water supply-indoor piping, mechanical structure, and automobile muffler that importantly consider initial
function of stainless steel pipe.
