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 are the sleeve couplings joined?
Generally used in high-pressure pipe, steel pipe, copper pipe, iron pipe are used
Q:The difference between expanding, clamping sleeve and welding pipe joint
Welded pipe joints: welded pipe joint applicable medium: oil, water, gas and other non corrosive or corrosive medium. The welding type sealing 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 and chemical engineering light industry, textile, metallurgy, aviation, defense, and ship system; also suitable for hydraulic transmission of various mechanical engineering, machine tools and other equipment pipeline. When the sleeve type pipe joint production can not meet the needs, and in the case of strong corrosion, priority can be adopted.
Q:What is pressing type pipe joint
A joint body core and buckling nut strictly, crimping connector still belongs to the soft seal
Q:Standard Specification for jacket type pipe couplings for card sleeve couplings
Specification sheet, thick tube, B (water gas pipe), thin steel tube, A (wire pipe), metric, English, nominal, nominal diameter * wall thickness mm nominal
Q:How to distinguish between flared pipe joint and welded 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.
Q:The pipe line of the hydraulic pressure pipe is formally installed
Three. Threaded pipe threads (GB 7306 is the same as ISO7/1)1. thread sealed pipe threads, without padding or sealing, can prevent leakage. The pipe thread with screw thread has two connecting forms: cylindrical internal thread and tapered outer thread, tapered inner thread and tapered outer thread. When the pressure is below 5 * 105Pa, the former connection is close enough, and the latter connection is usually used only at high temperature and high pressure.2. thread sealed pipe thread, there are two kinds of thread cone, cylinder. The external thread has only one form of taper. Tooth type is as follows: taper 1:16, tooth shape angle 55 degrees, old thread standard example: ZG3/8;
Q:Outside the wire (wire) of what the standard joint size
External thread type metal hose jointStructure and characteristics:The outer threaded end type metal hose joint is an extension of the JB/GQ0552-83 metal joint;
Q:The material is 304 stainless steel 1/4 "NPT" threaded joint. How much MPa pressure can be received?
I've seen a lot of discussion about the NPT thread's stress levels, and none of them are accurate.He who knows knows not to answer. It took time to find relevant global requirements. For your reference
Q:Who knows what the clamp joint standard is?
American Standard should be and not the same as ISO, but the actual products are the same?But in factories in the United States, they are strictly standard
Q:Specification for thread of gas couplings
1, the trachea quick change joints, referred to as pneumatic joints.2, pneumatic connectors have foreign brands and domestic brands.
