5. FAQ of Tubing Coupling of Grade L80


We have organized several common questions for our clients,may help you sincerely:


①How about your company?

One of the leading manufacturers and suppliers specializing in steel pipe products in China, mainly offering four series steel pipes including welded steel pipe (ERW, SSAW, LSAW and square and rectangle pipe), seamless steel pipe, hot dipped galvanized steel pipe and steel pipe with 3 layer polythene coating. We can provide customers different specification standards e.g. ASTM A53, ASTM A106, BS1387, API 5L, API 5CT, ISO3183 and etc. Our scope of supplying covers from 1/2" to 48" for the outside diameter of welded pipes, and 1/8" to 20" for the seamless pipes. 


Other than steel pipes we are also capable of supplying a wide variety of pipeline accessories, steel pipe fittings; valves etc. consists of our one-stop sales. The integrated sales & service ensures customers with various demands an easier access for purchasing management.


②How to guarantee the quality of the products?

We have established the international advanced quality management system,every link from raw material to final product we have strict quality test;We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.


③How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible.

Q:The name of the card sleeve joint
The two ends of the card sleeve is called the sleeve type right angle pipe joint
Q:PVC can the pipe joint be butted with the joint? How do I get it?
One is welding, the other is adhesive bonding, and the other is double headed thread connection
Q:What are the connecting forms of industrial pipe joints? Like buckling type connection,
The pipe joint use of light and handy, in a clean manner, widely used in metallurgy, mining, coal, petroleum, forging, ships, machine tools, chemical equipment and agricultural machinery hydraulic, pneumatic and lubrication fluid conveying pipeline system, particularly adapted to need often disassembled in the pipeline.
Q:What's the hydraulic pipe joint material?
Selection of pipe joints, the minimum is equal to the entire hydraulic system working state of the maximum working pressure setting the maximum working pressure for each joint, not only to consider the pump outlet pressure, also consider starting pressure relief valve. Therefore, in the design of complex hydraulic pipeline, the actual pressure is best measured by field measurements. The system operating pressure has been fixed, so the maximum working pressure of each selected pipe joint shall be checked.The maximum working pressure of the pipe joint can be changed by different sealing methods or according to the change of temperature: similarly, if the pipe joint chooses the elastic seal, it will get higher working pressure than the rigid seal.International standard set 4 times insurance coefficient, the reason is the practice of design thinking, the error of pipe joint device and equipment operation process may appear, the working condition of the system stability, in order to guarantee the system not paralyzed when in operation, so the insurance coefficient of the nominal pressure of the high.
Q:Press the hydraulic pipe fittings standard need to do what procedures
Press with 19mm four layer steel wire hose (Italy Manul manuli4sp) from the hydraulic tubing buckling parameters in the table look up with four layers of 19mm steel wire hose joint diameter is 37mm before pressing coat, rubber 33.5mm, the die diameter is phi 33mm,
Q:Classification of pipe couplings for hydraulic couplings
Hydraulic hose, high pressure ball valve, quick joint with odd intention and sleeve type pipe joint
Q:What's the meaning of the plumbing PVC pipe joint specification "1/2" "X12" and "1/2" "x18"?
Plumbing PVC pipe joint specifications 1/2, "X12" and "1/2" "x18" these two specifications belong to the British unit.
Q:Why are the sleeve joint leaks?
The hardness of the clamping edge is not enough, or the steel pipe is too hard. After the assembly, the clamping edge can not cut into the pipe wall to form a seal. Solve: replace the qualified card sleeve.The end face of the steel pipe is not vertical or clean, which hinders the proper installation of the pipe. Solution: carefully clean the end face before installation.The joint body and the steel with different axis, leading to the assembly is not correct, extrusion is not tight, at this time can be found in the card set apart and cut the pipe wall, left the marks of a single whole foot ring groove. Solution: when installing, make sure the joint is coaxial with the steel symbol.
Q:The material is 304 stainless steel 1/4 "NPT" threaded joint. How much MPa pressure can be received?
I've seen a lot of discussion about the NPT thread's stress levels, and none of them are accurate.He who knows knows not to answer. It took time to find relevant global requirements. For your reference
Q:What is the function of the pipe joint?
The hydraulic pipeline is mainly to transport hydraulic oil, the pipe joint is mainly for connection, installation and maintenance convenience.
