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.

Standards of Butt-Welding Concentric reducers:

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

Q:What material does the hydraulic pipe joint use? Carbon steel or cast iron?
Special requirements made of stainless steel or copper.The US has 37 degrees and 74 degrees. The cone and cone are fine teeth.
Q:May I ask what material EN39 is? Used to make a threaded pipe joint
EN39 is a European standard, the standard number is EN39:2001. The standard formal name is: carbon steel pipe for scaffolding.
Q:What is pressing type pipe joint
Belongs to a class of hose joint, joint sealing need to withholdA joint body and sleeve are generally formed
Q:What does the pipe connector type "10-R1/4" mean?
(Pipe, joints) hydraulic term is a part of a hydraulic system that connects the pipe or sets the pipe to the hydraulic element. This is a generic term for connections that can be assembled and disassembled in the fluid path.It mainly includes welding type, clamping sleeve type and flaring type.
Q:What are the types of tubing and pipe couplings applicable to each occasion?
Pipe joint is detachable between the tubing and tubing, tubing and hydraulic components of the connection, it should satisfy the convenient assembly and disassembly, reliable connection, reliable sealing, small size, large capacity oil, small pressure loss, good processing etc..
Q:What is the taper angle of flared tubular joints?
One end of the pipe is expanded to form an inner cone surface consistent with the cone angle of the pipe joint, the angle of the cone is 74 DEG, and the outer cone is the same as the angle of the inner cone of the pipe mouth, and the angle of the conical face is 66 deg.
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?
Sleeve type pipe joint: the working principle of the clamp sleeve is to insert the steel tube into the clamp sleeve, lock the sleeve with the nut, contradict the sleeve and cut into the pipe to seal. The utility model does not need welding when connected with the steel pipe, and is favorable for fire prevention, explosion prevention and high-altitude operation, and can eliminate the defects caused by careless welding. Therefore, it is a kind of advanced connecting device in pipeline, automatic control device, pipeline, oil refining, chemical, petroleum, natural gas, food, pharmacy, instrument and meter, etc.. Apply to oil, gas, water and other medium pipeline connection. The card connector has reliable, high voltage capability, high temperature resistance, good sealing and repeatability, installation and convenient maintenance, safe and reliable connection.
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:Can the pressure vessel pipe joint adopt G thread? Why?
The pipe thread is on the wall of the pipe for connecting threads. It has 55 degrees of unsealed pipe thread and 55 degree sealing pipe thread. The utility model is mainly used for the connection of pipelines, and the internal and external threads of the utility model are closely matched with two kinds of straight pipes and a conical pipe
Q:Apart from the air-conditioning, the high-pressure pipe is not tight enough. What shall I do?
Will affect the cooling effect, it is recommended to cut off the connector, and then use reaming device to expand after re installation. Charges will not be too high, dozens of blocks enough to be careful to be pit.
