Product Description:

Features standards and products of our butt welding fittings:

Features of butt welding fittings:

1.       High class materials

Our products only use high class raw materials of carbon/alloy steel pipes made from NKK or MANNESSMANN equipment for ordinary, high pressure, low/high temperature,boiler and other purposes.

2.       Uniform wall thickness and perfectly round

This can be achieved by our particular technical knowhow and our quality control program.

3.       Accurate dimension

Efficient piping work can be made only with fittings of correct dimensions and shapes. Our fittings are finished to have accurate straight/ plane ends, beveled angle...etc. to applicable standards by means of two or three spindle beveling machines.

Standards of butt welding fittings:

Our welding fittings are manufactured in compliance with the following appliance standards:

ASME B16.9   ASTM A234   MSS-SP43   WPHY60   JIS B2311   DIN2605

                      ASTM A403   MSS-SP75   WPHY65   JIS B2312   DIN2606

FAQ of butt-welding fittings:

1) Q: What’s your main product? Which kinds of products are more competitive in your product range?

     A: Our main products are steel flanges, pipe fittings and steel pipes.

     Competitive Items: flanges in stainless steel, carbon steel, alloy steel  and punching carbon steel

     Butt welded pipe fittings in stainless and carbon steel

2) Q: what’s your largest size of flange and fitting? How long is the  production cycle?
      A: The largest flange we could produce is 80’’ and the largest fitting is 50’’.

      In general, we spend 20-25 days in a 20-ton order. If necessary, we  could make it shorter.

Q:Auto air conditioning condenser and high pressure pipe joint leakage, can use sealant?
Glue can not be blocked, mechanical strength is not enough, the use of leakage will occur during the process
Q:Hydraulic pipe joint seal, with raw meal belt and sealant that good?
Hydraulic is not high temperature oil, usually with O ring, can not seal the oil, is not the joint surface is not good, can not cut off the replacement of joints, raw rubber tape, sealant is not reliable
Q:The expansion type pipe joint and the sleeve type pipe joint difference, everybody looks at the picture, this is belongs to that kind of?
The material of the pipe has a problem, it is a hose. So what kind of form do you have?. If the straitjacket of words, should belong to flaredfitting.
Q:PT1/4 large diameter pipe joint? No figure urgently
The thread has a taper of 1:16, equivalent to 55 degrees taper pipe thread, or ZG
Q:Apart from the air-conditioning, the high-pressure pipe is not tight enough. What shall I do?
The position of the station is wrong, the output is not working / the spanner angle is not right... The most simple, is to find a major wrench with a long handle and then force that, if the screw is not open, it may break pipe head, we should pay more attention to the....
Q:What is the manual pre assembly procedure for the EO-2 joint?
I. pre assembled1, EMB card sleeve type pipe joint pre assembly of the most important link, directly affect the sealing reliability. A dedicated preprocessor is usually required. The small diameter can be pre joint in a vise. The concrete method is to use a joint as the mother's body and press the nut and the sleeve onto the tube. The utility model mainly comprises a sleeve type through pipe joint, a clamping sleeve type end through connection head, a clamping sleeve type three way pipe joint and other patterns. 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.
Q:What does pipe joint "DD" mean?
The strengthening pipe joint is a medium strength cast iron, which has good casting performance, simple process and small casting stress
Q:The material is 304 stainless steel 1/4 "NPT" threaded joint. How much MPa pressure can be received?
The twenty-first page specifies the level of thread and material corresponding to the pressure application. Stainless steel thread used in the steam is 7 kg pressure (bar), the water temperature is above 105 degrees celsius. Other restrictions, standards.
Q:Who knows what the clamp joint standard is?
There are a lot of standard for fast mounting clamps.The actual production of the ISO clamp joints seems somewhat different from the standard,
Q:The pipe joint model is 1/2 "-14 teeth / inch"
British thread is the size of the thread in English, marked by the shape of cylindrical, cone two, according to the tooth type angle of 55 degrees, 60 degrees, two kinds
