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:What do you mean by pipe fittings 3/4?
Generally speaking, the standard is different, the corresponding caliber is also different. I don't know which one you're referring toThe pipe can be divided into many categories, there are pieces of pipe and socket welding pipe fittings, pipe trench, pipe fittings, sanitary fittings and so on. These fittings reference standard is not the same, even pieces of pipe standard also has many kinds, domestic GB/T12459, American Standard use of ASME B16.9 and ASME B16.28, and JIS2311 DIN2605 of Germany, Japan, and so many. GB GB/T12459 is divided into two series, the same "3/4" pipe fittings, the corresponding caliber is not the same. A series of peripheral dimensions and American Standard is basically the same, with the Russian standard size B is basically the same. So it's difficult to answer what the outside diameter of 3/4 is, and you need to refer to different standards. You can go to the "standard sharing network" above to check the corresponding standards, routine standards can be found, very practical!
Q:Joint type of pipe joint
Straight through joint, straight joint, three way joint, elbow, live nut joint, hinge joint, plug head, transition joint, etc.Double card sleeve assembly: front clamping ring, back clamping ring, nutMaterials are commonly made of stainless steel and carbon steelMetric, inch thread and American Standard NPT, PT, G are pipe thread.NPT is the abbreviation of National (American) Pipe Thread, an American Standard 60 degree taper pipe thread, used in North America. National standards refer to GB/T12716-1991
Q:Does the American and English fittings how to recognize it?
Inch thread is an isosceles triangle with 55 degrees, 60 degrees is made of an equilateral triangle, if you have a good tooth type gauge measurement, also the same number of teeth have more teeth than American english. Therefore, the two threads in your subject are short in length and inch in english.
Q:Is the joint of ground heating pipe and aluminium plastic pipe general?
There are many ground heating pipes. PERT, PEX, aluminum pipe, pb. Pert can only do floor heating coil, his joint is hot melt joint, PEX can be used as floor heating coil and system supervisor, and his joint is what you call aluminum plastic pipe joint (clamping connection)
Q:New standard, how can the pipe joint be labeled, such as "3/4" taper pipe thread?
The English system is 55 degrees of thread, and the internal thread of taper pipe is Rc3/4. The outer thread is R3/4The U.S. is 60 degrees
Q:Screw in pipe joint Dg10 what do you mean?
The diameter of the pipe can be divided into outer diameter, inner diameter and nominal diameter.The pipe is a seamless steel pipe pipe diameter by the letter D to represent, then additional outer diameter size and thickness, such as diameter of seamless steel pipe 108, a wall thickness of 5MM, denoted by D108*5, is also used outside said, such as De63 plastic pipe, such as reinforced concrete pipe, cast iron pipe, galvanized steel pipe, said the DN, in the design drawings is generally used to represent the nominal diameter, nominal diameter is a standard in order to design and manufacture and maintenance convenient set artificially, with nominal diameter, tube (or pipe) specification name. The nominal diameter of a pipe is not the same as the inside diameter and the outside diameter of the pipe,
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:How much is the monofilament of the 304 pipe joint?
This kind of pipe connection is very large, but the price depends mainly on how many sizes you want
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:Type parameter of pipe joint
