Product Description:

Steel Pipe Fittings Butt-Welding Eccentric Reducers

Features standards and products of our Butt-Welding Eccentric Reducers:

Features of Butt-Welding Eccentric 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 Eccentric 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 does R1/2 pipe joint mean?
Engineering diameter comparison table (commonly used)1 inches =25.4 mm =8 British cents1/2 is four points (4 English points) DN153/4 is six points (6 English points) DN202 in charge of DN84 in charge of DN156 in charge of DN201 'DN251.2 'DN321.5 'DN402 'DN502.5 'DN653 'DN804 'DN100
Q:What do you mean by the next connection in the pipe connection? How do you use it?
It is the through plate connection, when the joint goes through the iron plate and the like, use the next joint
Q:What is the difference between a D-LD2000 clamp type flexible pipe joint and a KRJ clamp flexible pipe joint?
Flexible pipe joint and flexible pipe joint difference, the difference is relatively large, the formulation with the domestic standard, causing confusion in the market there are three main points of differentA, the flexible pipe joint is the power plant smoke pulverized coal pipeline, the flexible pipe joint is coal construction design institute, the two products are used in different occasions, one is a high pressure resistant, high angle high the amount of compensation.
Q:Do you need adhesive for the sleeve joint of PVC wire pipe?
In my more than 10 years experience, in the piping, pipe joints such as glue, threading, threading device is easy to pass through the pipe joints, straight through and so on. Although the specification is to use glue, but the operation is very troublesome, I generally do not, no one to check you with no glue, just use the line tube inserted into the pipe joints or through the end can glue, threader easily through these joints. The line pipe is not easily disengaged and flooded when it is on the ground
Q:The gas cooker joint is pagoda shaped. Can it fall down and connect with bellows joint directly?
The provisions of China's domestic gas (gas interface with connection terminal interface), must be 55 degree cylindrical internal thread sealing pipe thread and external tapered thread sealing pipe thread, 55 degree conical internal thread and external tapered thread, 55 degrees of one of three non sealing pipe thread.A bellows is a tubular elastic device that is joined by folding wrinkles along a folded and telescopic direction. Bellows joints for civil water pipes and gas appliances are mostly 55 degree non hermetic pipe threads.Because the form of pipe joints is very large, they can be used in conjunction with the same thread and sealing form, so it is not sure whether the joint of the pagoda can be dropped or not.
Q:Can the pressure vessel pipe joint adopt G thread? Why?
3, pressure vessel, English: pressure vessel, refers to contain gas or liquid, carrying certain pressure airtight equipment
Q:About thread, pipe joint standard question
Or do you have to turn over every now and then?. Thread knowledge, personal feeling is quite complicated.
Q:What's the meaning of the pipe joint 14-M18*1.5? What's the thickness of the wall?
(two) 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. (three) when connecting the pipe, the pipe should have enough deformation allowance to avoid drawing the tube. (four) when connecting the pipeline, the lateral force should be avoided, and the lateral force will cause the seal to be too tight. (five) when connecting pipelines, should be a one-time good, avoid repeated disassembly, otherwise it will make poor sealing performance. Sleeve type pipe joint installation (1) of the pipe should need pickling pickling treatment according to the ninth chapter; (2) tube machine equipment cut tube with special cutting or sawing machine according to the required length, absolutely not allowed by fusing (such as flame cutting) or grinding wheel cutting; remove pipe end burr, metal cutting inside. Dust and dirt; remove the rust and dirt pipe joint; and also to ensure pipe roundness; (3) the sleeve nut, successively sheathed in the pipe sleeve front edge (small end) from the pipe mouth at least 3mm, then the pipe is inserted into the connector body bore, top to check; (4) slowly tighten the nut, while rotating the pipe until does not move, then tighten the nut 2/3 ~ 4/3 circle; (5) open the check card sets whether has cut the pipe correctly. The clamping sleeve does not allow axial movement, but slightly rotates; (6) after checking, tighten the nut again.
Q:What's the hydraulic pipe joint material?
The hydraulic oil of steel pipe and steel joint is not corrosive, so the hydraulic system is widely used in carbon steel joint, drinking water or pure water pipeline connection should not use ordinary carbon steel, before tightening air rules with brass, because the compressed air will carry water, gathered in the tube, if carbon steel will corrode the pipeline. The advanced air tightening machines do not produce moisture, so the rule is meaningless
Q:What is the reason that the rubber hose of the fire hose is flowing black oil?
This is the groove of the fire trench, the connection of the pipeline meets all the requirements and the quality is not satisfied. That is, the quality of aprons.
