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.

3) Q: Could you produce according to the drawings?

     A: Sure. We could produce according to the provided drawings, which  include forged and casted items.

4) Q: What kind of certificates do you have?

     A: We have ISO, TUV, API,SGS,BV etc. fittings in stainless and carbon stee

Q:Can the sleeve type pipe joint be disassembled and assembled several times?
The setting times of the sleeve type pipe joint are regulated. Generally speaking, the disassembly and assembly will affect the use of the clamping sleeveSome domestic tubes, nuts, silver plating) support multiple disassembly, because silver plating increased the number of inlay
Q:The difference between expanding, clamping sleeve and welding pipe joint
Sleeve type pipe joint: the working principle of the clamp sleeve is to insert the steel tube into the clamp sleeve, lock the sleeve with the nut, contradict the sleeve and cut into the pipe to seal. The utility model does not need welding when connected with the steel pipe, and is favorable for fire prevention, explosion prevention and high-altitude operation, and can eliminate the defects caused by careless welding. Therefore, it is a kind of advanced connecting device in pipeline, automatic control device, pipeline, oil refining, chemical, petroleum, natural gas, food, pharmacy, instrument and meter, etc.. Apply to oil, gas, water and other medium pipeline connection. The card connector has reliable, high voltage capability, high temperature resistance, good sealing and repeatability, installation and convenient maintenance, safe and reliable connection.
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:What is the taper angle of flared tubular joints?
Expansion type pipe joint applicable medium: oil, water, gas and other non corrosive or corrosive medium pipe joints, with steel pipe specifications requirements more flexible, and pipe welding
Q:How much is the monofilament of the 304 pipe joint?
Small size is cheaper, and one more thing is the thread standard you want to connect to
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:Will that be all right? Then there's the PPR pipe joint on the right. Is that ok?
If you don't feel comfortable, you can ask the master to change it for a whole 2 meter tube.
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:The material is 304 stainless steel 1/4 "NPT" threaded joint. How much MPa pressure can be received?
The material is 304 stainless steel 1/4 "NPT" threaded joint. How much MPa pressure can be received?Answer: test pressure 2.5MPa; work pressure is less than or equal to 1.5MPa.
Q:The pipe connections have different diameters. Reducing the diameter, what else?,
Six links, or even moreAccording to material classification, same material, different material
