List of ASTM Materials for Buttwelding Fittings

Advertisement

Americal Society for Testing and Materials (ASTM) has researched and defined various material standards for oil and gas industry. Properties of these materials depend on chemical properties of fluids to be handled, design temperatures and pressure as well of method of manufacture of pipe fittings. Many piping fittings like buttweld fittings are made by working them through various stretching and pressing operations. Here is a list of such materials for wrought steel buttwelding fittings.
