Metal hose fittings

The effect of Chinese metal hose stainless steel hydraulic hose couplings fittings Reuters is the first network sets of bellows coupling as a whole, together with a metal hydraulic hose adapters connector is metal hoses or other fittings, equipment coupled components. It normally guarantee media jobs in the pipeline system. Information joints usually bellows, network data sets, as much stainless steel main. When production costs decline, some larger diameter metal hose is not strong in transporting corrosive or non-corrosive media, carbon steel fittings are available; corrosive media work on metal hose connector case, if depicted the adoption of appropriate measures to avoid touching the medium, it is possible to manufacture carbon steel. Layout joints generally divided into spiral, flanged and fast three categories: 1, thread type: diameter 50
The effect of stainless steel metal hose connector is first the mesh sleeve and the bellows coupling as a whole, together with a metal hose connector is metal hoses or other fittings, equipment coupled components. It normally guarantee media jobs in the pipeline system. Information joints usually bellows, network data sets, as much stainless steel main.  When production costs decline, some larger diameter metal hose is not strong in transporting corrosive or non-corrosive media, carbon steel fittings are available; corrosive media work on metal hose connector case, if depicted the adoption of appropriate measures to avoid touching the medium, it is possible to manufacture carbon steel.Layout joints generally divided into spiral, flanged and fast three categories:
1, thread type: 50 mm diameter metal hose fittings, in the case of accepting a higher operating pressure, and many more screw-type main thread when tightening the future, within the two connectors on the outer taper surface work closely to complete the seal. Cone angle is usually 60 degrees, 74 degrees is also useful. The layout of the tightness, but it is necessary to guarantee the concentricity of the two pieces when docking device. To deal with the practice of engineering often see repeat demolition, installation and easy concentric and other issues, can be portrayed as the joint cooperation of the cone with the ball.
2, flanged: diameter of 25 mm above the metal hose joints, usually in the case of acceptance operation pressure, to the main flange disc, which cooperate in the manner of tongue and groove seal. Along the radial direction, and we also can slide axially Looper flange bolt tightening tension in the two-body effects of convergence. The layout of the outstanding sealing function, but the process is difficult, simple sealing surface bumps. In special situations that require quick release, it is possible to tighten the bolt through the hole gash, made ??quick release flange.
3. Express type: Path for various metal hose fittings 100 mm or less, and at the request of the use of rapid loading and unloading conditions, usually selected type fast. It is commonly used plastic or special fluorine rubber O-ring seal. When moving the handle must viewpoint future, the equivalent of fingers long thread is locked; O-ring will be kept more tightly, sealing function better. The layout in the fire, field and other necessary quick quick release most suitable occasion. Within a few seconds, with no need to use any special tools, it is possible to open a group or butt joints.

Pipe joint

The pipe joint is connected with the tool between the pipeline and the pipeline, can be the connection point between components and hydraulic pipe fittings assembly and disassembly. As a significant role in the tube, it is one of the two main components of hydraulic pipeline.
The pipe joint has a wide range, a pipe joint used in general can be divided into two kinds of fittings and hydraulic hose and fittings joint hard tube. If in accordance with the connection pipe joint and pipe to points, hard tube joint with flared type, sleeve type and welding type three, hose connectors are mainly withhold hose joint.
Pipeline of hydraulic system and connection pipe joint are also different, the pipeline is screwed into the end is used in connecting thread. Taper thread by virtue of his vertebrae and the use of PTFE sealing screwing operation of material, is mainly used in low pressure in the hydraulic system. Fine tooth thread sealing effect is very good, is often used in high voltage system, but it requires the use of combination washer or O type ring against the end face of the enclosed work, sometimes use a copper washer, it is more suitable for the connection of pipeline wall is thick, the system consists of a joint body, connecting pipe and a nut. When in use, the joint body is embedded in the target, with the use of said in front of the washer will face seal, between the joint body and taken over by the rubber sealing, sometimes using spherical seal method.
The pipe joint can be connected component belongs to the disassembly assembly type, which in addition to meet the normal steady connection, sealing strong, reasonable size, small pressure loss, good process performance and so on requirements, must also meet the requirements of assembly and disassembly is convenient. Therefore, do not underestimate the small pipe joints, because only it exists to support the existence of the whole hydraulic system.

The existence of stainless steel metal hose industry problems

1 the cost of rising prices. Iron and steel as the main raw material of stainless steel metal hydraulic hose adapters production has entered the price open and transparent small profits era, rising steel prices will push the stainless steel metal hose production cost;
The brand is poor in China 2 stainless steel metal hose connector industry, international competitiveness is weak. As a result of industrial concentration is low, backward technology, low price competition can not be avoided, China stainless steel metal hose is such a huge market has no real sense of "famous brand on the international";
3 fierce competition constantly eliminated a small stainless steel metal hose enterprise.
4 R & D strength is weak, insufficient capital investment. The technology progress of our country still stays in the overseas in twentieth Century 80 time, although it is a large number of the introduction of advanced technology and production lines, but the basic support for the technology digestion and absorption of the lack of hardware and software.
5 practical technology brain drain. At present, although China has engaged in research work in some colleges and universities, a lot of ethical research, patent papers have a very high level, but combined with production practice is not close, the theory into the finished product ability is poor.
