Our Suppliers


Carbon Steel and Low Temp Fittings and Flanges

We continually strive to be the premier supply chain solutions provider of fittings and flanges, and our preferred manufacturers can be found on the approved manufacturers lists (AMLs) of all major energy companies. We provide pressure and weld fittings, flanges, swages, and pipe nipples. We also inventory high-quality domestic and import fittings and flanges from 1/4 in through 36 in. Larger sizes are available on request.

High Yield Fittings and Flanges

DNOW has always distinguished itself from competitors by providing extra value to customers, and we continue this tradition by taking a strong position on supplying hard-to-find high yield fittings and flanges. We inventory 4 in through 30 in fittings and flanges, in 42,000 psi through 70,000 psi minimum yield material grades. Our High Yield Program provides fittings with properties beyond the requirements of national standard MSS-SP-75. Fittings furnished from our inventory meet the following criteria:

  • Lower carbon equivalent for greater weld-ability
  • All elbows (LR and 3R) suitable for field segmenting
  • All fittings 16 in and larger meet impact requirements for low temperature service

These properties represent an added value available at no cost to our customers.
