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:Will the moving angle of the air conditioner indoor be harmful to the connecting pipe joint?
There's nothing wrong with the moving angle. Our unit air conditioning because moving, we have been disassembled and assembled several times (copper tubes are disk, installation and then stroke straight), there is no leakage problems.
Q:Plastic pipe joint leakage, how to deal with better?
Repair seal.Specific operation, see the following points:Now that the water leaks, you'll find the main switch for this pipe and turn it off for later maintenance;
Q:Can the pressure vessel pipe joint adopt G thread? Why?
3, pressure vessel, English: pressure vessel, refers to contain gas or liquid, carrying certain pressure airtight equipment
Q:Can the copper tube use a clip on pipe joint?
Sleeve type pipe joint sealing pipe joint is applicable to oil, water, gas and other non corrosive or corrosive medium, with plastic pipe specifications are flexible, and pipeline connection, has the characteristics of reliable connection, good sealing performance, so it is widely used in oil refining, chemical industry, light industry, textile, defense, metallurgy, aviation, shipbuilding and other systems; also suitable for hydraulic transmission of various mechanical engineering, machine tools and other equipment pipeline
Q:Air conditioning pipe joints how to remove, the joint is ring, there are similar to the spring on the oil seal
There is a special set of air conditioning pipes, disassembly tools, plastic. Generally sold air conditioning parts and steam insurance shops have sold, not expensive, that is, twenty or thirty yuan. Like a set of 4 or 6 forget?. Clip into the air conditioning pipe and pull it out. The principle is the use of this tool will spring open, air conditioning pipe on the ring on the spring.
Q:Can flared and jacketed hydraulic couplings be used as gas line couplings?
The pressure of the pneumatic pipeline is usually 0.8MPa.Yes, the life is longer than the pneumatic one
Q:Hydraulic tubing connections are made of material steel
Such as carbon steel and cast iron, a much more used, less material costsBut if you're under a lot of pressure, try using carbon steel
Q:Why does the air conditioner outdoor pipe joint freeze and freeze in case of refrigeration?
Lack of fluoride: the tube frost, because the refrigerant has begun to vaporize here, into the internal machine has lost part of the heat absorption capacity of vaporization, air conditioning cooling effect worse.
Q:What joints do nylon hard tubes work on?
(I) flared type pipe jointApplication: 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, ship etc.; also suitable for hydraulic transmission of various mechanical engineering, machine tools and other equipment pipeline. Flared tube fittings are manufactured in the following six categories:
Q:What are the differences between hydraulic couplings and fittings and elbows?
The hydraulic pipe connection includes hose joint and steel pipe jointThe connector body does not include the nut clamp. There are straight through fittings, elbows, and 45 degree joints, etc..Elbows generally refer to joints of 90 degreesMy side is to do this piece, the United States PARKER Parker imported hydraulic hose, joints, quick connectorThere's contact information in the comments, thank you!
