What are Vessels?Vessels are equipment usually a closed container designed to hold gases or liquid at a pressure different from ambient pressure.

CONSTRUCTION MATERIALSCONSTRUCTION MATERIALS

•Generally, almost any material with good tensile properties that is chemically stable in the chosen application can be employed.• Common materials for OFON 2 Vessels include SA 516 GR 60, GR 70 ..etc.• Special materials like Nickel,Monel,Incolloy 800,Inconel 400 etc.

CONSTRUCTION MATERIALSCONSTRUCTION MATERIALS

•Many pressure vessels are made of steel and steel alloys like carbon steel,Normalized carbon steel etc.• Other very common materials include copper and polymers.
