What is the typical pipe material for steam systems? Pipes for steam systems are commonly manufactured from carbon steel to ASME B 16.9 A106. The same material may be used for condensate lines, although copper tubing is preferred in some industries.See all results for this questionsp.info Why does steam need to be piped when not in use?Stagnate condensate can form a mild carbonic acid when CO2 comes in contact with water. This accelerates corrosion faster than water alone. Steam systems should be piped to allow gravity drain-down when not in use, or should be blown out with compressed air at the end of each heating season.See all results for this questionsp.info Pipes and Pipe Sizing | Spirax Sarco - First for Steam ...A 100 mm Schedule 40 pipe has an outside diameter of 114.30 mm, a wall thickness of 6.02 mm, giving a bore of 102.26 mm.
