hose couplings types – What Is Piping

A hose coupling is a connector that connects a hose to another hose or tap of sprinkler systems or equipment. They are manufactured in different varieties and widely used in water, chemical, and oil & gas industries. Depending on service requirement hose couplings are made of various materials like brass, steel, stainless steel, aluminum, or plastic. The purpose of this article is to provide brief information about different types of hose couplings which are used in oil & gas applications. Purpose of Hose Couplings Couplings can be used in various conditions like: For loading & unloading tanker connection.For purging as well as flushing connection.In fire fighting network Fig. 1: Purpose of Hose Couplings Different Types of Hose Couplings: Following types of Hose Couplings are widely used: ElaflexTODOCam and Groove (Camlock) CouplingsAvery Hardoll dry-break couplings &Carter couplings Let me show 1 by 1 in detail. Elaflex Couplings: These hose couplings are produced by Elaflex and are used in petrol station equipment, Tank truck equipment, Aircraft refueling, chemical and pharma industries, LPG refueling, Marine applications, Rail Tankers, and Oil & Gas applications. Main features of Elaflex hose couplings are Elaflex hose coupling sizes - ½” to 4”Type of pipe connection – threaded & flangedAvailable Pressure classes - 150# & 300# (Working pressure up to 25 bar)The material of construction of the Elaflex coupling – Brass (for non-sour service), SS (for sour service)Manufacturing Std. – API RP 1004 / EN 14420 Fig. 2: Typical figure of Ela Flex Coupling TODO Coupling: Available sizes - 3/4” to 6”Type of pipe connection - threaded & flangedPressure class - 150# & 300# (Working pressure up to 25 bar)The material of Construction – Brass, SS, Aluminium, Hastelloy C & other on requestManufacturing Std. – EN 13480 and EN 13445TODO couplings are used for tanker unloading connection into a tank/vessel, because of the integral check valve.Elaflex couplings are used for tanker loading connection from a tank/pit. Fig. 3: Typical figure of TODO Coupling Cam & Groove (Camlock) Couplings: Available sizes - 1/2” to 6”Type of pipe connection - threadedPressure class - 150# (Working pressure up to 17 bar)The material of Construction – Brass, SS & Aluminium Fig. 4: Typical figure of Camlock Couplings.
