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

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:PVC can the pipe joint be butted with the joint? How do I get it?
PVC pipe joint and butt joint, the best way is to add between the two joints of the same type of pipe, and then use special glue to connect
Q:What material does the hydraulic pipe joint use? Carbon steel or cast iron?
The joints are mainly welded, flared and jacketed.Cast iron is generally used on low pressure. Not welded, sealed with raw material tape and thread. 0~1.6mpa, right?.
Q:What's the difference between the half pipe joint and the branch seat?
The 1. half pipe joint standard half pipe joint specification production pipe connection form the connection form is divided into three kinds of socket weld connections, welded connections, threaded connections. Pressure rating: pipe pressure rating, general socket welding, butt welding fittings form the pressure rating of 3000LB (SCH80), 6000LB (SCH160), 9000 (XXS). Thread connection type, pipe pressure grade is divided into 2000LB, 3000LB, 6000LB. The commonly used pipe Name: 90 degree elbow, three, four, 45 degree oblique three, couplings (pipe joints, and copy), half coupling (half pipe joints, pipe cap, semi Bele), Union (by either), Taiwan Branch (branch block). The power plant took over the seat, forged three, threaded plug, the wire, bushing, strengthening pipe joint pipe.
Q:The expansion type pipe joint and the sleeve type pipe joint difference, everybody looks at the picture, this is belongs to that kind of?
The material of the pipe has a problem, it is a hose. So what kind of form do you have?. If the straitjacket of words, should belong to flaredfitting.
Q:What are the materials for fire hose fittings and connections? Can I use stainless steel 316?,
. Because the flame retardant material is added to the coating material, the temperature resistance of the product is improved compared with other similar products. Therefore, when the ambient temperature rises rapidly, it will not affect the use. Internal and external fire tubes are much better than galvanized pipes in service life and performance.
Q:Classification of pipe couplings for hydraulic couplings
Welded pipe fittings, high pressure hoses.Transition type pipe joint, jacket type pipe joint and three type pipe joint,
Q:What is the manual pre assembly procedure for the EO-2 joint?
4, the pre assembly force should not be too ambassador, the inner edge of the card sleeve is just inserted into the outer wall of the pipe, and the clamping sleeve should not have obvious deformation. When the pipeline connection, and then according to the specified tightening force assembly. Phi 6-1 card sleeve tightening force is 64-1 15N, 16 MMR 259n, Phi Phi 18mm for 450n. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.Matters needing attention:1, prohibit adding sealant and other fillers. Some people in order to obtain better sealing effect, in the card cover with sealant, the result of sealant is poured into the hydraulic system, causing hydraulic components, such as plugging holes.2. When connecting the pipe, should make the pipe has enough deformation allowance, avoid the pipe by tensile force.3. When connecting the pipeline, it should be avoided to be subjected to lateral force, lateral force caused by the assembly seal is not strict.4, when connecting the pipeline, should be a one-time good, avoid repeated disassembly, otherwise it will make poor sealing performance.
Q:Connect with stainless steel tube with 304 stainless steel clip type pipe joint,
Because it is clamping, used for steam to consider the impact of temperature, it is not recommended for toxic, harmful, medium pressure above the high temperature gas.
Q:What joints do nylon hard tubes work on?
The pipe joint is the connecting tool between the pipe and the pipe, and it is the connection point between the component and the pipe.There are three kinds of hard tube joints: flaring, clamping and welding
Q:Hydraulic jointWho knows the hydraulic connection "3/8*25.4=9.525" refers to the connection?
The most important part of the pre assembly of sleeve type pipe joints 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.
