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:How do you explain the pipe joint?
Steel pipe marking should be DN, DN is nominal diameter, DN20 galvanized pipe does not mean that the outer diameter of the pipe is 20mm, the outer diameter of the steel pipe, but 26.8mm; DN15 galvanized pipe, the outer diameter is 21.3mm.
Q:What are the standard drawing numbers for hydraulic couplings?
Regulations:Assembling of pipe sleeve type pipe joint(I) pre assembledThe most important part of the pre assembly of the sleeve type pipe joint directly affects the reliability of the seal. 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 do you mean by the next connection in the pipe connection? How do you use it?
The professional name is only wearing a joint pipe through the wall, using a splint or interlayer
Q:About thread, pipe joint standard question
The world's three major thread standards, individuals feel very good, although six or seven years of work

Q:What does flaring pipe joint mean?
The joint is tapered and the pipe is straight, which requires the use of special tools to extend the end of the pipe to the bell mouth
Q:What do you mean by "s" in the standard of pipe joint?
Did the landlord say "S" and "L"? S is a high voltage application, for example, at the P port. L is low voltage applications, generally used only in the oil return.
Q:What is the nominal diameter of the phi 1/2 in the pipe joint?
1 inches =25.4mm.1/2 "- 4 thiophene, 3/4" - 6 thiophene, etc..Pipe, pipe thread and machining are often used in these old units, but they are not legal units of measurement in our country.Installation industry and business are commonly used in this unit.
Q:Why does the air conditioner outdoor pipe joint freeze and freeze in case of refrigeration?
Fluorine slightly more: thick pipe icing or frost, because the refrigerant inside the machine is not completely vaporized, back to the end is still vaporized heat absorption.Excessive dust in the inner filter screen or evaporator: the internal air circulation is not smooth, resulting in the backflow of the subcooled refrigerant, the icing of the thick pipe, and the cooling effect.
Q:PEX floor heating pipe fittings and fittings are aluminium plastic pipes?
4., antistatic, easy to flammable fluid delivery;5. good electromagnetic shielding performance;6., good flame resistance, to achieve GB8624 refractory (B1) level;7. good insulation performance.(two) hydraulic performance of aluminum-plastic composite pipe inner surface roughness of thin wall excellent, very smooth, fluid friction resistance is small, no fouling phenomenon which affects the flow of water flux than the metal pipe, and because it has a certain flexibility, can effectively reduce the water supply of water hammer and fluid pressure shock and noise.
