How to Select the Correct Steam Hose Assembly Determine required hose size The hose size required is usually fixed by size of fittings or pipe to which the hose is to be connected. It is important that you do not select a hose with an inside diameter larger than the diameter of the preceding pipe. Determine condition of steam (saturated or superheated) Locate the actual rated working pressure and temperature on the steam chart. Any point on the heavy line is saturated steam. Select couplings required Gates recommends interlocking* and permanently crimped types of couplings for steam hose applications. These are identified as: • Interlocking, ground joint • Interlocking, washer joint • Permanently crimped *Remember to retighten bolts on a regular basis. Find actual rated working pressure and temperature Take pressure and temperature readings just ahead of the hose connections. Select the correct hose From the table below, select the hose that fulfills the requirements of both the condition of the steam and the rated working pressure. Determine length required Length require is almost always dictated by the application. Maintenance and inspection For proper maintenance and inspection of interlocking and permanently crimped steam hose assemblies, refer to ARPM IP-11-1.

Due to continual product improvements, Gates reserves the right to alter specs without prior notice. CAUTION! • When electrical continuity is required, ground the wire braid in the hose to couplings with aluminum, copper or stainless-steel staples. • Steam can be dangerous material. Play it safe – stay within the limits of published recommendations. • Do not alternate between steam and water. .
