Standard-Wall Stainless Steel
Threaded Pipe Nipples and Pipe
Designed for low-pressure flow applications, this pipe is also known as Schedule 40. Alloy 20 stainless steel pipe has the best corrosion resistance of all the stainless steel pipe we offer. Alloy 20 stainless steel is also known as Carpenter 20 and resists cracking from stress and corrosion.
Seamless pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

Medium-Pressure Stainless
Steel Threaded Pipe Fittings
Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.
Fittings that meet ANSI/MSS SP-114 adhere to high-quality standards for heat treating, material thickness, and marking. Alloy 20 stainless steel fittings have the best corrosion resistance of all the stainless steel fittings we offer. Alloy 20 stainless steel is also known as Carpenter 20 and resists cracking from stress and corrosion.
