Exactly what A Hose Fittings

by:Yober     2020-05-23
Hose fittings consists of: stainless steel hose, metal hose, corrugated hose, plastic hose. Stainless steel hose fittings mainly describes the material from the 304 stainless steel or 301 stainless steel] made hose fittings. Uses: utilized automatic meter signal wire protection hose fittings. Used shield the precision optical ruler to protect the sensor distinct stainless steel hose fittings. Has good flexibility, corrosion resistance, high temperature, abrasion resistance, tensile strength and water challenge. And to provide some shielding effect. Mainly refers to a kind of metal hose fittings is spiral-shaped bellows; one other is circular corrugated pipes. Spiral corrugated pipe is a corrugated spiral arrangement of the tube-shaped shells, ripples amid the two adjacent a helix angle, all the ripples can be connected by a spiral line. Annular corrugated pipe is corrugated tube was closed circle-shaped shell, wave and wave ripples in series between the rings. Ring bellows or welded pipe seamless pipe with the forming process. Constrained by the processing methods, compared to spiral-shaped bellows, the single-tube length is usually shorter. Ring bellows has the regarding good elasticity, rigidity small. Corrugated hose fittings as a flexible pressure pipe what the liquid delivery system, to complete pipe or machinery, equipment, mutual displacement connectors, absorb vibration energy, can play a vibration, noise along with other effects, has excellent flexibility, quality Light, corrosion resistance, fatigue resistance, high temperature and many more features. Two associated with plastic hose fittings, an uniquely airtight, watertight, such as rocket propellant for the transport, gas, water heater; the other is in combination with a continuous winding material, the common winding of corrugated pipe used for protection of cables, such as magnetic card telephones, machine tools, incredible lamp of corrugated pipe is on the inside production process into the wire attach. Plastic composite pipe may be the first in order to cast iron pipe water supply pipe, its basic structure always be five, that is, about the inside were plastic, hot melt adhesive, aluminum alloy, hot melt adhesive, cellophane. Aluminum plastic composite hose fittings has good insulation properties, corrosion inside and outside the wall is not easy, caused by inner smooth, fluid resistance is small; it as free to bend, so installation is straightforward for establishing. As the water supply hose fittings, aluminum plastic composite hose fittings of sufficient strength, on the other hand too much lateral force, it will affect the strength, so should be out or buried a wall pipe construction, but should not buried subterranean. (Aluminum-plastic composite pipe could be buried underground, such as to warm the pipes used one may be the plastic composite pipe) aluminum plastic composite pipe connection is ring-style (can be compression type), so construction First, we must pass rule test pressure, test rest and memory connect is secure. Second, to prevent frequent vibration, so that card set loose. Third, the entire installed capacity should remain sufficient avert pull from. Application of plastic composite pipe. In water supply and heating pipes with thermoplastic pipes instead in the traditional domestic hot galvanized steel hose fittings will be the current trend. Industrial sector according to market demand, develop the introduction of plastic pipes of varied materials, one of which can be used for cold and hot water and hot water heating, building high-density polyethylene (HDPE) and aluminum composite hose fittings, that is, plastic composite (PE -AL-PE) pipes. Aluminum plastic composite hose fittings in China developed rapidly, about 85 domestic aluminum pipe production line, annual production capacity of 150 million m, construction of aluminum tubes are investing inspiration. To this end the author information relative to relevant domestic and international research conducted on the plastic composite pipe integrated domestic situation and development trend brewing an objective evaluation, look after reference.
