Product Description:

Steel Pipe Fittings Butt-Welding Concentric reducers

Features standards and products of our Butt-Welding Concentric reducers:

Features of Butt-Welding Concentric reducers:

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.

Q:Hot tap water pipe joint leakage, what method can be repaired?
The original hot connection place cut, a new joint with a pipe section, and then pick up
Q:How should thread thread be broken in the joint?
Here are a few options for you to choose from:1, in the middle of the broken wire hole, the wire breaking out with broken wire puller or other fixtures.
Q:Hydraulic pipe fittings, DIN, GB, American Standard how to distinguish?
Joint type end straight joint and a straight joint, three joints, elbow, with movable nut joint, hinge joint, plug, etc. transition joints double sleeve joint. The clasp, clasp, nut material used is stainless steel and copper metric, American and English standard thread standards NPT, PT, G is the pipe thread.NPT is National (American) Pipe Thread. The 60 degree taper pipe thread belongs to the American Standard, for North America. The national standard is available on the GB/T12716-1991
Q:What is the difference between the pipe and the pipe joint?
A metal tube 1, ordinary carbon steel wire (wire casing pipe) 2, metal flexible pipe (galvanized pipe, stainless steel pipe, plastic coated metal snakeskin snakeskin tube)
Q:Quick plug and card sleeve joint sealing which good?
Sure is a pipe joint of sleeve type is applicable medium: oil, water, gas and other non corrosive or corrosive medium, sealing pipe joint, with aluminum pipe specifications are flexible, and pipeline connection, has the characteristics of reliable connection, good sealing performance, which is widely used in chemical industry, oil refining light industry, textile, metallurgy, aviation, defense, and ship system; also suitable for hydraulic transmission of various mechanical engineering, machine tools and other equipment pipeline.
Q:How many bonding methods are there in the belt joint?
2. cold adhesive joint, which adopts the cold bonding adhesive joints, with adhesive as the raw material, the method of conveying belt ends are connected together, the key depends on the effect of cold adhesive glue, do seamless processing. Because this method has the advantages of high strength, no noise, no vibration, simple operation, short time joint, so it is widely used, but from a practical point of view, because the process is more difficult to grasp, also affect the adhesive on the quality of the joint is very large, so it is not very stable, in addition, cold bonding conveyor belt do not apply to wet temperature and material requirements.
Q:Will that be all right? Then there's the PPR pipe joint on the right. Is that ok?
You don't see this picture very clearly. You mean there's a lot of right side connections, right?
Q:Air conditioning pipe joints how to remove, the joint is ring, there are similar to the spring on the oil seal
Tools, inside six corners, wrenches, screwdrivers.1, fluoride start cooling, compressor work closed high pressure valve, run for one minute, close the low-pressure valve, stop. Unplug the power plug (remember).
Q:What are the types of tubing and pipe couplings?
According to connection tubing and pipe joints, pipe joints are welded, sleeve type, expanding type, press type form; each form of pipe joint,
Q:Why does the air conditioner outdoor pipe joint freeze and freeze in case of refrigeration?
Normal: a thin tube (pressure pipe) cool or lukewarm, thick tube (tube) cool or cold dew.
