Stainless steel 316L Pipe Fittings

Stainless steel 316l buttweld fittings

What are the benefits of sourcing Stainless Steel 316L Buttweld Fittings from us?

Corrosive environments containing seawater, chlorides, and halides employ these components. Stainless steel 316L buttweld fittings comprise chromium, nickel, and molybdenum, but the ultra-low percentage of carbon lends them superior corrosion resistance than comparable grades like 316.

SS 316L fittings are readily weldable and perfect for petrochemicals, pharmaceuticals, wastewater treatment, and food processing.

We ensure premium-quality products adhering to internationally accepted standards, like ASTM A403 WP316L pipe fittings. Our company priorities thorough testing via techniques like flattering, pitting resistance tests, and spectrography. Different designs are available to address client needs, like elbows, a UNS S31603 316L tee, and concentric reducers.

We also guarantee damage-free, quick delivery around the globe in client-specified packing.

What are the common challenges with testing large-diameter Stainless Steel 316L Buttweld Fittings?

Large-diameter fittings are indispensable in the petrochemicals and power generation sectors. However, adequate safety and performance testing of such stainless steel 316L pipe fittings poses multiple challenges:

  • Must assess greater thickness with higher precision
  • Must meet industry standards
  • An SS 316L reducer must compensate for variations in diameter (esp. inner dimensions) and eccentricity
  • Hydrostatic testing involves considerable resource consumption
  • Expensive due to requirements of expertise and technology

We use manipulative and non-destructive approaches like hydrostatic testing, visual inspection, and automated ultrasonic examination to guarantee the quality of a stainless 316L pipe bend.

What are the industry standard dimensions for Stainless Steel 316L Buttweld Fittings? How do they compare to those of other grades of stainless steel?

These fittings conform to the ASTM A403 specification and are available in sizes from 1/8 to 36 inches. You can procure a Werkstoff Nr. 1.4404 stub end in standard sizing from 15 NB to 300 NB across piping schedules. We stock a vast repertoire of fittings from 1/2 to 48 inches (up to 1200 NB).

Clients should note that a stainless steel 316L elbow and similar fittings are typically not as readily available in various sizes as grades like 304, mainly because of higher cost and more specific usage.
