What Are Approved Fittings?

Approved fittings are industrial pipe fittings that meet specific international and regional quality standards set by certifying authorities like:

  • API (American Petroleum Institute)
  • ASTM (American Society for Testing and Materials)
  • ASME (American Society of Mechanical Engineers)
  • BS (British Standards)
  • DIN (Deutsches Institut für Normung – German Standards)
  • ISO (International Organization for Standardization)

These fittings are tested and certified for use in critical applications like oil & gas, petrochemicals, refineries, marine, power plants, and construction.

Where Are Approved Fittings Used?

Approved Fittings are used in a wide range of industries, including construction, oil and gas, chemical processing, and water treatment. They are critical in residential plumbing, HVAC systems, and various industrial applications, helping to maintain proper flow and pressure within pipes.

What Makes Industry-Approved Fittings Crucial?

In industries like oil & gas, chemical processing, and marine, the performance of pipe fittings is paramount.
