16 Inch UNS S31803 S32750 duplex Stainless Steel Tube , SAF 2205 Stainless Steel Pipe For Sea Water Transport

 

Duplex stainless steel was developed to solve the common corrosion problems encountered with 300 series stainless steels. "Duplex"  incomplete means a series of  austenitic stainless steels, such as 304 stainless steel, or pure ferritic stainless steel, such as 430 stainless steel.

 

The advantage of a duplex structure is that it combines the good qualities of ferritic alloys (stress corrosion cracking resistance and high strength) with austenitic alloys (easy to manufacture and corrosion resistant).

 

 

Application :

 

  • Petroleum
  • Chemical industry
  • Instrument
  • Industrial transportation
  • Mechanical structure industry
  • Need high corrision ability pipe's industry , such as offshore industry etc

 

 

Advantages:

 

  • Superior surface finish,
  • Better mechanical property
  • More precise dimension
  • Perfect inspection method and inspection equipment

 

Size: 1/2” to 24” (DN15 ~DN600), outer diameter up to 610mm
Rate:  SCH5S to SCHXXS
