Product Description:

Steel Pipe Fittings Butt-Welding Concentric reducers

Features standards and products of our Butt-Welding Concentric reducers:

Features of Butt-Welding Concentric reducers:

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 Concentric reducers:

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

                      ASTM A420   WPHY42    WPHY70   JIS B2313   DIN2616

                      ASTM A860   WPHY52                                       DIN2615

FAQ of Butt-Welding Concentric reducers:

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 copper tube use a clip on pipe joint?
Clamping sleeve type pipe joint for copper pipe connection.Copper pipe connections are commonly used:
Q:What is the size of the PVC pipe joint?
[1] the PVC joint size is in inches, 1 inches =25.4 millimeters.[2] PVC: polyvinyl chloride (English: PolyVinyl Chloride abbreviation: PVC) is a use of a chlorine atom to replace one of the hydrogen atoms in polyethylene polymer material. PVC is an amorphous white powder with less degree of branching
Q:Hydraulic jointWho knows the hydraulic connection "3/8*25.4=9.525" refers to the connection?
A part of a hydraulic system between a high pressure tubing and a high pressure tubing.Classification: hydraulic hose, high pressure ball valves, quick couplings, odd intention ferrule type pipe joint, welded pipe joints, high-pressure hose, transition pipe joint, sleeve type pipe joint, three way pipe joint, non-standard pipe joint, flaredfitting, rectangular pipe joint, rotary tube connector, quick connector, stainless steel pipe fittings, copper fittings.
Q:20ppr pipe joint is not what brand, 20ppr pipes can weld?
As a result, there may be differences in the coefficient of thermal expansion, which may lead to leakage at the joint.
Q:Inside and outside the threaded joint, one end of the internal thread (G),
The cylindrical internal thread and the taper outer thread form a column / cone fit; the taper internal thread and the taper outer thread form the cone / cone matching.
Q:Classification of pipe couplings for hydraulic couplings
Welded pipe fittings, high pressure hoses.Transition type pipe joint, jacket type pipe joint and three type pipe joint,
Q:The difference between the reducer joint and the strengthening pipe joint
The reinforcing pipe joint essentially is that when the branch pipe is connected to the supervisor, the pipe joint is enlarged by the reinforcing pipe, which is beneficial to welding, and then the other end is connected with the branch pipe and can be welded by socket welding,
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: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:What does national standard joint jb/t6381.2-92 mean?
The current version is: JB/T, 6381.2-2007, cone welded, straight through, 55 degrees, non hermetic, pipe, threaded, pipe joint. The type, size and technical specifications of the taper sealing welded straight through 55 degree non sealing pipe thread pipe joint are specified.
