As a result,a hot air pipe needs to be made of materials that are capable of handling higher than normal temperatures.Industries tend to favor steam venting hoses that are made from materials such as thermoplastics,silicones,and metals like aluminum and stainless steel because they can all survive direct contact with extremely hot air.Steam Mains and Drainage Spirax SarcoOnce the steam main is up to operating temperature,the rate of condensation is mainly a function of the pipe size and the quality and thickness of the insulation.For accurate means of calculating running losses from steam mains,refer to Module 2.12 Steam consumption of pipes and air heaters.Steam Gaskets McMaster-CarrChoose from our selection of steam gaskets,including over 350 products in a wide range of styles and sizes.In stock and ready to ship.
