Hose fittings consists of: stainless steel hose, metal hose, corrugated hose, plastic hose.
Stainless steel hose fittings mainly describes the material of a 304 stainless steel or 301 stainless steel] made hose fittings. Uses: utilized for automatic meter signal wire protection hose fittings. Used to guard the precision optical ruler to protect the sensor type of stainless steel hose fittings. Has good flexibility, corrosion resistance, high temperature, abrasion resistance, tensile strength and water weight training. And to provide some shielding effect.
Mainly refers into a kind of metal hose fittings is spiral-shaped bellows; the additional is circular corrugated pipes. Spiral corrugated pipe is a corrugated spiral arrangement of the tube-shaped shells, ripples in between 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 from the forming process. Constrained by the processing methods, compared to spiral-shaped bellows, the single-tube length often shorter. Ring bellows has the regarding good elasticity, rigidity small.
Corrugated hose fittings as a flexible pressure pipe positioned in the liquid delivery system, to atone for pipe or machinery, equipment, mutual displacement connectors, absorb vibration energy, can play a vibration, noise some other effects, has excellent flexibility, quality Light, corrosion resistance, fatigue resistance, high temperature and many other highlights.
Two types of plastic hose fittings, a completely airtight, watertight, such as rocket propellant for the transport, gas, water heater; the other is combined with a continuous winding material, the common winding of corrugated pipe used for protection of cables, with regard to magnetic card telephones, machine tools, while the lamp of corrugated pipe is as production process into the wire clip.
Plastic composite pipe is the first in order to cast iron pipe water supply pipe, its basic structure ought to five, that is, from the inside were plastic, hot melt adhesive, aluminum alloy, hot melt adhesive, plastic.
Aluminum plastic composite hose fittings has good insulation properties, corrosion inside and outside the wall isn't easy, as a consequence of inner smooth, fluid resistance is small; it as free to bend, so installation in your own home for creating. As the water supply hose fittings, aluminum plastic composite hose fittings of sufficient strength, but if too much lateral force, it will affect the strength, so should be out or buried inside of the wall pipe construction, but should quit buried metro.
(Aluminum-plastic composite pipe can be buried underground, such consumers warm the pipes used one could be the plastic composite pipe) aluminum plastic composite pipe connection is ring-style (can also be compression type), so construction First, should pass rule test pressure, test by means of is completely. Second, to prevent frequent vibration, so that card set loose. Third, the length of the installed capacity should remain sufficient to avoid pull right off.
Application of plastic composite pipe. In water supply and heating pipes with thermoplastic pipes instead among the traditional domestic hot galvanized steel hose fittings will be the current not paid labor. Industrial sector according to push demand, develop the introduction of plastic pipes several materials, would like a super which can be employed 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 encouragement. To this end writer information as per with relevant domestic and international research conducted on the plastic composite pipe integrated domestic situation and development trend of creating an objective evaluation, offer reference.
