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.

Difficulties and challenges in the development of stainless steel metal hose industry

Core Tip: Stainless steel metal hydraulic hose  plays an important role in modern industry, used in civilian areas are also many. Under the new situation, the industry is facing many difficulties and challenges, major enterprises
Stainless steel metal hydraulic hose and fittings plays an important role in modern industry, used in civilian areas are also many. Under the new situation, the industry is facing many difficulties and challenges, the major companies have demonstrated a positive attitude to deal with.
1, technical improvements and R & D capabilities further enhanced.
A accelerate industrial innovation system, promote the development of stainless steel metal hose and industrial applications;
B development of environmentally friendly production and recycling economy, the implementation of national and industry energy conservation objectives, tasks, resources and environmental constraints ease;
C promote stainless steel metal hose industry in fiber, high-end equipment, energy saving and environmental protection, brand marketing and other aspects of national strategic emerging industries, cultural industries combined, especially prominent stainless steel metal hose products in new materials, new energy, energy saving and environmental protection strategy The new innovations in the field of development and application of optical fiber industry closely integrated development model.
2, property conscious. Government departments vigorously outreach intellectual knowledge and improve awareness of intellectual property stainless steel metal hose SMEs. Conduct special training, training for stainless steel metal hose IPR SME managers. Counseling on patents, patent agents, patent and patent warning service stainless steel metal hose SME activities, fostered a number of stainless steel metal hose SMEs proprietary advantage, improve industry SME creation, utilization, protection and management of intellectual property rights ability.
3, improve the quality and standard management. SMEs to carry out activities in the industry's commitment to quality, build quality and integrity of the system, to improve the quality level of integrity and self-discipline. Strengthening SME brand building guide, stainless steel metal hose clothing SMEs to enhance brand value and provide technical support. SMEs to actively promote the industry standard of good conduct business activities to create and improve the management level of standardization.
Development of stainless steel metal hose industry enterprises and governments to be joint action, in the government's macro-control of the overall situation of the industry, the difficulties and challenges will be transformed into an effective driving force for development.
