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?

Q:What is the difference between a D-LD2000 clamp type flexible pipe joint and a KRJ clamp flexible pipe joint?
Two, flexible pipe joint clamp type flexible pipe joint ring part and the pipe connection is socket welding, so as to facilitate the installation, the product imported from America, KRJ is the butt welding, which is helpful for pipeline installation, the details can query the professional manufacturers to askThree, ring thickness of flexible pipe joint is greater than 30 mm, which can increase the wear resistance of air impact according to the principle of friction, the latter is only considered high pressure, without considering wear so over 16 mm in thickness general below.
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:What are the links between hydraulic components and pipe couplings that are used to prevent leakage?
If it is a super high pressure seal (70 MPa or more), the metal cone can be used for hard sealing, that is, the inclined joint of the pipe joint is matched with the inclined plane at the component thread.
Q:Consult the problem of the pressure at the entrance and exit of the pipe joint
Assuming two load infinite, a 1MPa load (cylinder or motor) can free action, three exits are linked together, so that the two load does not move, a move, three oil outlet pressure gauge pressure is 1MPa.Assume that one or more of the three is not loaded, and the three outlet pressure is 0, or very small. The three outlet pressure gauges are 0MPa.,You don't design, I'm scared
Q:How to use the clamp type pipe joint?
The clamping sleeve type straight through joint has clamps at both ends, and it is worn at the end of the pipe which needs to be connected, and then it is clamped and connected with the nut,
Q:Can the pressure vessel pipe joint adopt G thread? Why?
1 、 pressure vessel pipe joints do not use G thread, because G thread is not sealed enough.
Q:The name of the card sleeve joint
The two ends of the card sleeve is called the sleeve type right angle pipe joint
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 does pipe joint "DD" mean?
Parts that work in a weak corrosive environment, such as covers, bearings, valves, hand wheels, etc., are joined mainly for connection, installation and maintenance.
Q:Puvc pipe joint leakage how to do?
Common leakage of different types of water pipes1, water pipe leakage reason: this situation generally belongs to relatively minor, it is not difficult to solve, it is because the water pipe and faucet did not connect well.2, the leakage of water pipe: water pipe hardening or long time foreign matter blocked the water pipe, resulting in rupture.
