STAINLESS STEEL EQUAL TEE ASTM A403 WP304/316L THICK WALL THICKNESS

ASTM A403 Abstract

ASTM A403 WP316L covers the standard for wrought austenitic stainless steel fittings for pressure piping applications. The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. Forging or shaping operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of two or more of these operations. All fittings shall undergo heat-treatment.

Chemical and product analyses shall be performed and shall conform to the required chemical composition in carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, and titanium. Tension test shall be done on the fitting material to determine the tensile properties such as yield strength and tensile strength. Fittings supplied under this specification shall be examined visually for surface discontinuities, surface checks, and mechanical marks.

A403 WP316L Fittings Application

Fittings are used wherever liquids, gases, chemicals and other fluids are created, processed, transported, or used.

Range of industries is very wide, as shown below:

• Energy related

Oil and gas industries, including upstream (exploration and production), midstream (transportation by ships, pipeline, rail, trucks; storage and wholesale) and downstream (refining into fuels or chemicals; marketing and distribution). Power plants using fossil or nuclear fuels. Geothermal energy for harnessing heat from the earth.

• Food and beverage production

From basic ingredients to elaborate desserts. From milk, to juices and other beverages. Cold chain to keep produce fresh, drinks and frozen foods at a set temperature. Desalination plants to transform seawater into drinking water for arid areas and various tropical islands.

• Pharmaceuticals and biotechproduction

Medicines and vaccines that treat illnesses and help restore bodies and minds to their top conditions.

• Semiconductor manufacturing

Microchips that go into all electronics, including smartphones, tablets, computers, television sets, telecom networks, etc.

• Pulp and paper production

Newsprint, glossy paper, cardboard boxes, books, writing paper, etc.

• Production of construction materials and plastics
