180 Degree Elbow
180-degree elbow is a common pipe fittings, mainly used to change the direction of flow of fluids or gases this elbow, widely used in oil, natural gas, chemical, water supply and HVAC and other industries, especially in the need for complete reversal of the direction of the fluid pipeline layout is particularly important.
Overview
Materials: cast iron, stainless steel, alloy steel, calcined cast iron, carbon steel, non-ferrous metals and plastics.
Carbon steel elbow: characterized by low cost and short production cycle.
Stainless steel elbow: suitable for corrosive liquid transportation pipeline, with good corrosion resistance.
Alloy steel elbow: suitable for piping systems that need to withstand high pressure.
