ASTM A WPL6 Pipe Fittings – ASTM A WPL6 Elbow Exporter from Mumbai

WPL6 is a normalized grade of carbon steel that has been Charpy Impact tested at degree F for use in low temperature service. These are widely appreciated for excellent quality, corrosion abrasion and high tensile strength with long life service.

Materials shall consist of forgings, bars, plates, seamless or fusion welded tubular products with filler metal added, and shall be produced by open-hearth, basic-oxygen, or electric-furnace process.

Forging or forming operations shall be performed by one or a combination of two or more of the following procedures: All welding shall be completed prior to the austenitizing heat treatment, which shall be executed in the normalized, normalized and tempered, annealed, or quenched and tempered conditions.

Steel specimens shall conform to required values of chemical composition, tensile strength, yield strength, elongation, wall thickness, and Charpy V-notch impact value.

All fusion-welded butt joints shall undergo radiographic examination, asmt hydrostatic testing of fittings is not required in this specification. Repair welding shall be permissible for parts made to dimensional standards.

These fittings are for use in awtm piping and pressure vessel service at low temperatures. When desired, one or more of these supplementary requirements shall be specified in the order.

Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
