5. FAQ of Casing Coupling of Grade K55


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:Can the sleeve type pipe joint be disassembled and assembled several times?
The European and American card sleeve pipe joint is a standard part, it can be disassembled and assembled many times, but it is better to check the sealing cone into the pipe, whether the inner component has the wrong face, the pipe is better to choose the new connection.
Q:Is the joint of ground heating pipe and aluminium plastic pipe general?
Pb can only serve as the system supervisor, the pipe joint is hot melt joint, and the aluminum plastic pipe can only be the system supervisor. That is, the joint of PEX and aluminum pipe is universal. If your site pipe is PEX, the tube is generic and cannot be generic if it is PERT.
Q:Auto air conditioning condenser and high pressure pipe joint leakage, can use sealant?
Should replace the high-pressure pipe or tube sealing ring in order to solve the problem.
Q:How about the water pipe fittings and millimeters?20mm is 425mm is 6Why
20mm is not a scientific argument.Should be the plastic pipe, the nominal outer diameter of DN20 plastic pipe, only corresponds to 4 points of the metal pipe threadThree,If it is a metal tube, it should be nominal diameter Dn15, and the corresponding English pipe thread is 6
Q:The pipe line of the hydraulic pressure pipe is formally installed
Hydraulic pipe fittings - thread standard twoClassification of threadsThe 1. threaded internal and external threads two;2. according to the shape of teeth can be divided into: 1) triangular thread 2) trapezoidal thread 3) rectangular thread 4) sawtooth thread;3. by line, single, head and multi thread;4., according to the direction of rotation, two kinds of left and right threads, the right is not marked, left plus LH, such as M24 * 1.5LH;5. according to different uses are: metric common thread, thread sealed pipe thread, non threaded sealing pipe thread, 60 degrees taper pipe thread, metric taper thread, etc.Two. Metric general threads1. metric screw thread with a capital M, tooth type angle 2 degrees =60 (alpha tooth type half angle);2. metric ordinary thread by pitch, coarse teeth, ordinary thread and fine teeth, two kinds of ordinary thread;2.1. coarse tooth ordinary thread mark generally does not indicate the pitch, such as M20 means coarse thread; fine tooth thread mark must indicate the pitch, such as M30 * 1.5 for fine tooth thread, in which pitch is 1.5.
Q:Consult the problem of the pressure at the entrance and exit of the pipe joint
Assuming that your 3 oil outlet, load is infinite, as follows, three load (cylinder or motor) are not action, three outlet pressure is 2MPa, three outlet pressure gauge pressure is 2MPa
Q:Standard for fabrication of jacket type pipe couplings for card sleeve couplings
1, card sleeve end through pipe joint (GB/T 3733-2008)2, sleeve type cone thread straight pipe joint (GB/T 3734-2008)3, card sleeve end through long pipe joint (GB/T 3735-2008) 4 and card sleeve taper thread long pipe joint (GB/T 3736-2008)5, card sleeve straight through pipe joint (GB/T 3737-2008)
Q:Classification of pipe couplings for hydraulic couplings
Non standard type pipe joint, flared pipe joint, right angle pipe joint, rotary pipe joint, quick joint, stainless steel pipe joint, copper joint.
Q:Can the pneumatic pipe connection be carried through the water?
Yes, but it will leak. Or do you need a special pipe joint?
Q:What are the reducing, reducing, reducing, etc in the pipe joint?
You said reducing diameter may be tapered pipe thread, concrete view of pipe joint information, more detailed. You'd better have a picture and see it.
