What is the role of pressure in the performance of a stainless steel 317L pipe fittings?

These widely used fittings get produced from stainless steel with a low amount of carbon (hence, the L) and the addition of molybdenum. Stainless steel 317L pipe fittings endure high pressure and temperature in the oil and gas industries, chemical processing, and other industrial applications.

They deliver a tensile strength of 515 MPa. SS 317L buttweld pipe fittings are chosen for high-pressure applications exposed to harsh and abrasive chemicals. They deliver strength and low failure rates.

What are the 7 advantages of ASTM A403 WP 317L Buttweld elbow?

Elbow pipe fittings change the direction of the flow by a specified angle. Buttweld fittings, as the name suggests, require welded on at the ends to connect the pipes. Selecting an ASTM A403 WP 317L buttweld elbow(where WP indicates “Wrought Pipe”) for your application can reap several advantages:

  • It resists corrosive agents like acetic and formic acids, chlorides, and bromides. It can also tolerate pulp liquor and bleaching solutions.
  • Good resistance to creep, pitting, and stress-triggered rupturing
  • Suitable for high temperatures up to 871-899°C
  • Stainless steel 317L buttweld fittings can limit contamination.
  • They can resist intergranular corrosion.
  • Combats the tendency to pit when in contact with phosphorus acids.
  • It does not experience scaling at ambient to high temperatures.

How can I make sure the DIN 1.4438 Tee are put properly?

Installing these components cautiously is imperative for failure- and leak-proof performance. You must ready the pipe by checking its thickness and material and clearing it of contamination before putting the DIN 1.4438 tee. The piping must be certified as suitable for the component.

During the installation, you should exert the correct amount of force. Over-tightening is detrimental to the strength of SS 317L pipe fittings and also affects the flow.

As a final step, check the installation with a gap gauge. It prevents gaps in the pipeline that are dangerous for personnel safety.

Where can I use SS 317L Fittings?

The thermal properties and corrosion resistance of SS 317L fittings make them appropriate for:

  • Chemical processing
  • Petrochemicals
  • Nuclear and geothermal power
  • Food, beverages, and dairy
  • Bitumen upgraders
  • Paper and pulp production
  • Textiles
  • Semiconductors
  • Construction
  • Desalination plants (seawater into potable water)
What UNS S31703 Reducer certifications and test reports are available ?

These fittings connect pipes of varying dimensions, effectively reducing the diameter. Manufacturers of a UNS S31703 reducer can club these test reports (below) into a Mill Test Certificate. The latter is also called an MTC or MTR. Clients can also request additional testing.

  • Chemical composition (results of spectrography and radiography)
  • Test results for mechanical properties like tensile strength and hardness
  • Magnetic inspection report
  • Results for hydrostatic testing
  • PMI report (Positive Material Identification)
  • Raw materials certificate
  • Third-party inspection
