common winding of corrugated pipe used for protection

Safety joint is a special geological formation in the drilling drilling or special operations when connected to the drill column when the most lower part of drill pipe used to protect the upper part of a joint. Again introduce the hose fittings causes corrosion. Stainless steel hose fittings mainly refers to the material from the 304 stainless steel or 301 stainless steel hose fittings. If the protective layer is damaged, the following steel STS prepaid meter Manufacturers began to rust. If the protective layer is damaged, the following steel began to rust. Constrained by the processing methods, compared to spiral-shaped bellows, the single-tube length is usually shorter. Ring bellows has the advantage of good elasticity, rigidity small. Annular corrugated pipe is corrugated tube was closed circle-shaped shell, wave and wave ripples in series between the rings. 

In the event of sticking, burying drilling accident, can be unloaded from the safe to open threaded joints, and made all the drill ground for further processing accident; the fishing hose fittings, use it to connect over the salvage equipment, can also be card dead in fishing tools, easy to open from unloading safety joints and make drill pipe; in oil wells into the formation under the experimental test device to the middle, its upper safety joint also need to connect the local level is a serious card test device death easy to open from unloading safety joints, made all the drill pipe. Used to protect the precision optical ruler to protect the sensor line of stainless steel hose fittings. Can paint or oxidation-resistant metal (for example, zinc, nickel and chromium) in carbon steel plating to ensure, however, as people know it, this protection is only one kind of film. And to provide some shielding effect. 

Uses: used for automatic meter signal wire protection hose fittings.. Has good flexibility, corrosion resistance, high temperature, abrasion resistance, tensile strength and water resistance. 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. Metal and atmospheric oxygen reaction in the surface oxide film. Pressure as a flexible corrugated hose fittings installed in the liquid delivery system, to compensate for pipe or machinery, equipment, mutual displacement connectors to absorb vibration energy, can play a vibration, noise and other role, with excellent flexibility, quality Light, corrosion resistance, fatigue resistance, high temperature and many other features.Introduces several types of hose fittings. Metal and atmospheric oxygen reaction in the surface oxide film. Ring bellows or welded pipe seamless pipe from the forming process.

 Two types of plastic hose fittings, a totally airtight, watertight, such as rocket propellant for the transport, gas, water heater; the other is used with a continuous winding material, the common winding of corrugated pipe used for protection of cables, such as magnetic card telephones, machine tools, while the lamp of corrugated pipe is in the production process into the wire clip. Can paint or oxidation-resistant metal (for example, zinc, nickel and chromium) in carbon steel plating to ensure, however, as people know it, this protection is only one kind of film. PA nylon hose fittings (PA), modified by the import raw material, is the kind of high-tech products bellows, high toughness, high impact, bending properties, high temperature, surface brightness, abrasion resistance, chemical corrosion resistance fuel, electrical insulation> 200MΩ, halogen free flame retardant environmental protection is widely used in automotive wiring harness, electronic, mechanical wiring harness and other fields. Again introduce the hose fittings causes corrosion. Ordinary carbon steel to form oxide of iron oxide to continue to expand corrosion and eventually the formation of holes. Mainly refers to a kind of metal hose fittings is spiral-shaped bellows; the other is the annular bellows. Ordinary carbon steel to form oxide of iron oxide to continue to expand corrosion and eventually the formation of holes. Safety joint central square by the coarse threaded buckle, it is the most easy to unload drill pipe column to open the link
