5. FAQ of Tubing Coupling of Grade J55


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.

Q:Hot tap water pipe joint leakage, what method can be repaired?
The best cut off a re installation, as long as not concealed pipes into the wall should be implemented, and the most thorough, because the advantages of PP-R pipe is higher than the local welding strength, ensure tightness of the whole pipeline.
Q:Will the moving angle of the air conditioner indoor be harmful to the connecting pipe joint?
There's nothing wrong with the moving angle. Our unit air conditioning because moving, we have been disassembled and assembled several times (copper tubes are disk, installation and then stroke straight), there is no leakage problems.
Q:The union bonnet (Union Bonnet) and bolted bonnet valves (Bolted Bonnet) the same?
There is no bonnet flange that is threaded directly.
Q:The difference between expanding, clamping sleeve and welding pipe joint
Flaredfitting: flaredfitting medium: oil, water, gas and other non corrosive or corrosive medium pipe joint with steel pipe specifications and flexible pipe welding, has the characteristics of reliable connection, good sealing performance, so it is widely used in oil refining, chemical industry, light industry, textile, metallurgy, national defense, aviation, shipbuilding and other systems; also suitable for hydraulic transmission of various mechanical engineering, machine tools and other equipment pipeline.
Q:What's the meaning of the pipe joint 14-M18*1.5? What's the thickness of the wall?
I found that even if the same manufacturer of a batch of goods, the cone of these joints on the depth of the hole is often different, resulting in a leak, and this problem is often neglected. The correct approach is to connect the end of the pipe with what kind of joint, and the corresponding connection ends are prefabricated with the same type of joint, so that the leakage problem can be avoided to the maximum extent. The ends of the pipe shall be flush. The pipe should be flush in sawing grinding wheel and other tools, and burr cleaning and blowing with high pressure air before use. When installing, the coaxiality of pipe and joint body should be kept as far as possible. If the pipe deflection is too large, it will cause sealing failure. If the pre loading force is unfavorable, the inner edge of the ambassador card sleeve is just inserted into the outer wall of the pipe, and the clamping sleeve should not be deformed obviously. When the pipeline connection, and then according to the specified tightening force assembly. Phi 6-1 card sleeve tightening force is 64-115n, 16 MMR 259n, Phi Phi 18mm for 450n. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.
Q:What is the difference between the PVC joint and the PVC pipe joint?
What are the specifications of PVC threading tubes?:A metal tube 1, ordinary carbon steel wire (wire casing pipe) 2, metal flexible pipe (galvanized pipe, stainless steel pipe, plastic coated metal snakeskin snakeskin tube)
Q:Is the thread at the two ends of the card sleeve the same?
Sleeve type pipe joint sealing pipe joint is applicable to oil, water, gas and other non corrosive or corrosive medium, with plastic pipe specifications are flexible, and pipeline connection, has the characteristics of reliable connection, good sealing performance, so it is widely used in oil refining, chemical industry, light industry, textile, defense, metallurgy, aviation, shipbuilding and other systems; also suitable for hydraulic transmission of various mechanical engineering, machine tools and other equipment pipeline.
Q:What are the names of all types of hydraulic pipe couplings?
Welding type, sleeve type and flared type, according to the function of many kinds of joints, such as: the end of the straight joint and straight joints, three joints, elbow, with movable nut joint, hinge joint, plug, adapter etc..
Q:What do you mean by pipe fittings 3/4?
Supplement:1 inches =25.4 mm, =8 British points, 1/2 is four points (4 British points), DN diameter 15mm, 3/4 is six points (6 points), DN20mm.
Q:PEX floor heating pipe fittings and fittings are aluminium plastic pipes?
PEX floor heating pipe joints, pipe fittings are used for special connection with soft star joints, plastic materials are used to connect the machinery.Comparison of advantages and disadvantages between aluminum plastic tube and PEX tubeAluminum tube: plastic composite pipe is a pipe is more popular in previous years on the market, the current market there are relatively well-known HSBC and Kim, due to its lightweight, durable and convenient construction, its flexibility is more suitable for use in the home. The main drawback is that when used as a hot water pipe, due to long-term thermal expansion and cold contraction, it will cause the wall of the pipe to be dislocated so as to cause leakage.
