Stainless Braided Hoses

Our high quality stainless steel braided hoses are available in different grades and can be made with any connections. This product’s pressure and chemical compatibility make it unique and highly versatile as it is suitable for a wide range of applications across various industries. The hose assemblies are manufactured, assembled, and tested following the relevant ISO 10380 standard. Not all stainless steel hoses are created equal. Hoses are manufactured with a 4:1 safety factor for example the burst pressure is 4 times the maximum working pressure. The hose test pressure is 1.5 times the maximum working pressure. All Hoses are manufactured in accordance with ISO10380 and AS4041 to customer specifications. All hoses are tested and certified before dispatch. Many methods of testing are available such as Hydrostatic, Pneumatic, Vacuum and dye penetrant. Other finishing options include Oxygen cleaning, nitrogen packing and many more. Stainless braided hoses can be used in many applications ranging from Steam lines, Chemical transfer or simply as a Vibration Eliminator.
Temperature
The working pressure of corrugated hose is calculated at 20°c, as the temperature of the hose increases, the working pressure is reduced. The reduction in pressure can be calculated, using the temperature correctional factor chart, which is located on the data specification sheet.
Pressure
Pressure Loss - when installed in a piping system, pressure is lost due to the corrugations of the hose causing friction with the medium, reducing the flow rate. This problem can be alleviated by increasing the diameter of the hose. The Operating pressure of the hose determines the service life (lifetime of the hose) this can also be affected by the following: Pressure Fluctuations - Pressure surge is a sudden increase in pressure, which causes the hose to violently shake which fatigues the corrugations, leading to premature failure.Pressure Pulsing - where the pressure of the hose constantly rises and reduces, also fatigues the corrugations and leads to premature hose failure.

Hose Protective Options

There are many protection options which can be fitted to the hose to help extend the life of your hose assembly and reducing the risk to the operator. Protection may be required against extreme temperature, dragging, excessive user bending, careless handling, etc.
Silicone Sleeve
Manufactured In accordance with AS1072, this silicone coated, fibreglass braided sleeve is designed to protect the hose against exposure from fire/flame, exhaust, steam and even molten metals- up to1200°c. Also used to protect users from handling while hot. Fixed to the hose after manufacture using crimp rings.
Spring Guard
Fitted to the hose during manufacture, and fixed to the ends by welding. This spring forms a barrier between the hose and any rough surface the hose may be exposed to. Available in galvanised and stainless steel, in standard pitch and with close pitch ends – which offer excellent protection to the ends of the hose.
Interlock Guard
Stainless steel interlock hose can not only be used inside the hose to create a smooth bore and reduce velocity, but it can be used on the outside as a excellent form of protection. Its thick and durable stainless steel construction makes it ideal for the most demanding applications. Commonly used for cryogenic delivery assemblies.
