¡¡¡¡Movable-joint pipe fitting is a patented product of Movable-Joint Flexible Socket Joint Pipeline Coupling Technology invented by Pro. Ge Wenyu, and four series of products are derived according to this technology:

¡¡¡¡£¨1£©Nut locking series of products: suitable for the coupling of small-caliber (¦µ15¡«¦µ150) pipelines, working pressure: P¡Ý2.0Mpa.

¡¡¡¡£¨2£©Flange locking series of products: suitable for the coupling of medium/small-caliber (¦µ50¡«¦µ500) pipelines, working pressure: P=1¡«6.0Mpa.

¡¡¡¡£¨3£©Buckle locking series of products: suitable for the coupling of large/medium-caliber (¦µ200¡«¦µ5000) pipelines, working pressure: P=4.0¡«10.0Mpa.

¡¡¡¡Those with higher pressure requirement are accepted to be developed.

¡¡¡¡(4) Taper sliding locking series of products: suitable for the coupling of various kinds of hoses.

¡¡¡øMovable-joint pipe fittings can be used as the connectings of pipelines made of marious materials, such as:
¡¡¡¡ welded tube, plastic-covering steel tube, seamless steel tube, stainless steel tube, copper tube, aluminium-plastic tube, cast iron tube, plastic tube, steel-plastic composited tube, FRP tube, concrete tube, rubber tube, fibre tube and soft plastic tube.

¡¡¡øMovable-joint pipe fittings can be used as the connectings of pipelines of different shapes:
¡¡¡¡ round tube, elliptic tube, rectangular tube and polygonal tube.

¡¡¡øMovable-joint pipe fittings can be used as the connectings of pipelines of different purposes.
¡¡¡¡1¡¢Pipelines for construction: water supply & drainage, hot & cold water, heating, air conditioning, fire fighting, gas, wire conduit etc.
¡¡¡¡2¡¢Pipelines used in industry: the transmission pipeline of acid, alkali, salt liquid, gas, gasoline, diesel, coal oil, lubricant, powders, pasty and granular materials.
¡¡¡¡3¡¢Underground pipe network: large-scale oil, gas and water conveying pipe network and various city underground pipe networks.
¡¡¡¡4¡¢Submarine pipe network: marine water, gas, oil and cable conduit.
¡¡¡¡5¡¢The water, gas, oil and cable conduit on ships, warships and various equipments.
¡¡¡¡6¡¢The fast assembly & disassembly water, gas, oil and cable conduit specially used for the field army.
¡¡¡¡7¡¢The pipeline coupling in earthquake region (free rotatable and shrinking).
¡¡¡¡8¡¢Pipe fittings used for rapid leak stopping and repairing (without cutting off the water and gas supply).
¡¡¡¡9¡¢Connecting to graft new pipes (without cutting off the water and gas supply).
¡¡¡¡10¡¢Connecting for various hoses.

¡¡¡øVarieties of movable-joint pipe fittings:
¡¡¡¡ coupler, elbow joint, tee joint, cross, female thread adapter, male union, flange union, various reducer joint, various rotating tube joint.



Merits and Characteristics of Yongan Pipe Fittings£º
1.The installation quality is reliable, lasting, durable and will last for 50 years without seepage.
2.All the pipe fittings are movable. It is so convenient and fast to install&maintain that a wrench is enough no matter how large the project is.
3.Unnecessary for using screw-taper, electirc welder, electricity etc, which means a economization of equipments cost, maintenance charge etc.
4.Unnecessary for professional mechanic. Everyman can deal with the installation after 10 minutes' of training so that we can save 50% of the wages for workers.
5.No wasting in application (wasting ratio of traditional thread pipe fittings is among 10-15%) and unnecessary for movable union¡¢winding jute, adhesive tape so that we can save materials charge.
6.Applying Yongan Pipe Fittings to oil&natural gas pipelines, can remove creep destroy stress accumulated in the pipelines and ensure the safe running of the pipelines from brittleness & tractility fracture.
7.Shortening the time for a project. Increasing the efficiency to 3-5 times, saving 80% of the manual labor charge and reducing 15-20% of the engineering cost. Even more than 60% of the engineering cost will be saved in developed countries. It is named favorably by foreign businessmen as Pipelines Sandwich.

Yongan Pipe Fittings has four structures and ten series of products:
