Sleeve for gas welding Simper 6, 9, 12 mm
Sleeve corresponds to GOST 9356 - 75
Sleeves GOST 9356 75 - flexible pipes are used for feeding to the welding apparatus of liquid fuel and oxygen gas. Sleeve is divided into 3 classes.
Class I is designed for supplying propane, butane, town gas and acetylene, designed for pressure 0.63 MPa;
Class II is used to supply mineral spirits, gasoline, kerosene, and mixtures thereof, is designed for the pressure of 0.63 MPa;
Class III is used for supplying oxygen, it is designed for a pressure of 2 MPa and 4 MPa.
GOST 9356 - 75 sleeve consists of an inner and an outer rubber layer, filament - reinforced carcass. Robust structure according to product reliability and durability.
Depending on the purpose and scope of application of the sleeves, the color of its outer layer has a different color. Thus, the sleeve for the liquid fuel is colored yellow, the sleeve for gases - red, oxygen sleeve GOST 9356 75 - in blue. Hose 75 GOST 9356 undemanding in operation: in addition to excellent adaptability to hostile environments, it is able to withstand high pressures and temperatures from - 55 to + 70 degrees Celsius.
In order to weld the sleeve could be distinguished, use the marking system. To do this, the entire length of the hose put down an embossed inscription with sleeves type designation of its internal diameter and guests, regulatory quality indicators.
