Welding hose manufacturers offer a variety of hoses for the safe conveyance of various fuel gases like acetylene, propane and oxygen for welding applications. These hoses come in different sizes and lengths to accommodate various applications like brazing, cutting, soldering, bending, forming, heating, and cleaning. These hoses are also available in flame retardant and vinyl coated variants. These hoses are designed to withstand a wide range of temperatures, pressures, chemicals and weather conditions. They are used in a number of industrial applications such as automotive manufacturing, power generation, construction and mining.
Gas welding hoses are usually color coded to distinguish the type of gas that it transports. They are rated by the working pressure that they can safely withstand. Some hoses are also rated by the cylinder connection size – A, B and C.
The hoses are typically made of black synthetic rubber and high tensile synthetic textile reinforcement, which helps them withstand the extreme temperatures, pressures and chemical resistance required for the application. The hoses are also provided with a thermoplastic coating, which improves their performance and prolongs the life of the hose. Some types of hoses are also available with a tamper evident plastic cover for protection from accidental punctures.
These hoses are offered in standard lengths of 10, 25 and 50 feet. They are also available in bulk hose reels of up to 700 feet. They have a maximum working pressure of 200 psi, and are designed to meet ARPM IP-7-2011 requirements. They are compatible with oxy-acetylene welding equipment and can be used in a variety of industries including automotive, forestry, food or beverage, marine, aerospace or aviation, and oil field.
Before purchasing a gas welding hose, it is important to check the working pressure of the hose, as this will determine how much gas it can hold before bursting. A good quality hose will be able to withstand a pressure of up to 200 psi. In addition, it is also a good idea to check the nipple’s seating surface and if possible, test it for permeation by filling the hose with water and turning the nozzle on.
The nipple is the part of the hose that connects to the regulator or torch connections. Its shape is designed to match the internal seat of the connections and a clamp helps lock the hose in place on the nipple. This design prevents air from escaping and ensures that the hose can withstand high-pressure use.
The nipple is also often distinguished by the swivel nut and a ferrule. While the swivel nut makes it easier to rotate the hose, the ferrule is an important element in preventing leaking. The size of the nipple and swivel nut can also vary depending on the type of hose and gas to which it is connected. It is crucial to choose a suitable nipple and swivel nuts to ensure that the hose is compatible with your equipment. The hoses are also offered in different lengths and can be fabricated to custom specifications.
