Duplex Stainless Steel Piping can:
Deliver many years of economical service life
Provide outstanding corrosion resistance

DUPLEX STAINLESS STEEL PIPING/Duplex Schedule 5 Stainless Steel Pipe

The manufacturing of chemicals, petrochemicals,and oil & gas products, exposes process equipment to highly corrosive fluids. Analyses of fluids, pressures, and manufacturing temperatures used in these processes have shown Duplex Stainless Steel Pipe to be very corrosion resistant.

The fluids used in chemical processing are extremely corrosive and the materials of construction for processing equipment require very special consideration. Without correct specification, conditions will rapidly decline, leading to unit repair or replacement and expensive manufacturing downtime.

The following information is provided as background on Duplex Stainless Steel, the alloy's characteristics, its strengths and how consideration of a Duplex Stainless Steel Piping/Duplex Schedule 5 Stainless Steel Pipe System could be the answer to corrosion.

Duplex Schedule 5 Stainless Steel Pipe offers long-term and cost-effective methods to prevent damaging corrosion.

Life Cycle Benefits of Duplex Stainless Steel Piping Systems

Duplex Schedule 5 Stainless Steel Pipe is highly cost-effective over the entire life cycle of the equipment. Properly maintained, Duplex Stainless Steel Piping can operate for decades, making them a very economical choice over other reactive metals.

Welded Pipe Specifications

Usually it will be to ASTM A312. If it is to ASTM A358 then there are various Classes available as shown below. The Class Number dictates how the pipe is welded and what non-destructive tests:

Class 1:	Pipe shall be double welded by processes employing filler metal in all passes and shall be completely radiographed.
Class 2:	Pipe shall be double welded by processes employing filler metal in all passes. No radiography is required.
Class 3:	Pipe shall be welded in one pass by processes employing filler metal and shall be completely radiographed
Class 4:	Same as Class 3 except that the welding process exposed to the inside pipe surface may be made without the addition of filler metal.
Class 5:	Pipe shall be double welded by processes employing filler metal in all passes and shall be spot radiographed.
