SPIRAL S.A.W. STEEL PIPE
 
 
 
 

CAPACITY

  • Produce a wide range of large diameter spiral S.A.W. pipe products from 400mm to 2,600mm in capacity 200,000m.tons per year with coating and lining
 
 

PRODUCTS

  • Coated and wrapped steel pipes for water service
  • Steel pipe pile for foundation
  • Steel pipe sheet pile with clutch set
  • Coal-tar enamel and epoxy coating
  • Liquid epoxy and modified epoxy coating
  • Fusion boned epoxy coating
  • Polyethylene coating
  • Polyurethane coating and other special coatings for marine service
 
 

CHARACTERISTICS

  • High strength and durability allow steel pipe to be used in high-pressure applications.

  • Inside and outside coating make the life of pipe semi-permanent.

  • Dong Yang's pipe maintains its shape, without bending or breaking, when submitted to forces caused by setting of the base soil even when the pipeline is buried.

  • Steel pipe's extreme strength eliminates the need for supports at welded joints when pipe is buried.

  • Extreme ease of welding and cutting allow minor repairs to be executed without interrupting water flow.

  • Dong Yang's large diameter, extended length and special pipes can readily be produced.

  • Dong Yang's light-weight pipe is easily transported and installed even in
    underground applications.
