Product Description:

1,Ductile Iron Self Restrained Pipe Description :

The ductile iron self restrained pipe manufactured by SYI foundry are mainly used for conveying many fluid media such as water, oil and gas, are widely used in various pipeline projects for metallurgy, mine, water conservancy, petroleum and urban public service utility. Self-restrained joint adopts the T type joint sealing structure. Compared with T-type joint, adds a welded bead on spigot, and open-end locking ring, a gland and connecting bolts to provide the joint with good anti-slippage performance. The locking ring and the gland can slide between each other, so that the joint had certain axial stretching and deflection capability.

2,Main Features of the Ductile Iron Self Restrained Pipe:

The diameter is from DN 80 to DN 2000(Tyton, Class K7/9/14) under standard ISO2531 4179 8179 EN545, normally work length is 6 meters, Tyton socket-spigot, K9.

The ductile cast iron pipe, cast pipe & cast iron pipe manufactured by SYI is mainly used for conveying fluid media.

5.FAQ:

We have organized several common questions for our clients,may help you sincerely:

1.Q: Why would you choose ductile iron pipe rather than other pipe materials?

 A:The reasons are obvious for that not only ductile iron pipe possesses the inherent strength and flexibility of ductile iron, combined with proven corrosion protection systems, but also the cost savings can be achieved from design to installation and commissioning.

 2.Q:Why can you guarantee the inner of pipes can’t be corroded?

 A: High alumina cement mortar lining and sulphate-resistant cement mortar lining. These two special linings are applicable to inner anti-corrosion for sewage pipes, improving resistance to erosion of the sewage components.

Q:Qianwei County ductile iron pipe which tool to use cutting convenience?
Cutting method for cutting ductile iron pipes, in order to obtain neat kerf, we should start with a direction of play saw saw to end. If the requirement of the section is not high, the direction of sawing can be changed gradually to reduce the resistance and facilitate cutting in.
Q:Is the crankshaft material forged or ductile iron?
Other crankshafts are not clear about the car crankshaft. These two materials are useful, but the trend is to use ductile iron
Q:What is a graphite cast iron pipe?
There is a graphite tube, but there is no graphite cast iron (if not ductile iron)
Q:Does the cast iron pipe for spheroidal graphite need corrosion protection when laying underground?
Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
Q:Nodular cast iron, heat treatment process and so on
White cast iron is one of the defects. Firstly, control of carbon equivalent, carbon equivalent is not too high. The second inoculation is reasonable, the step of determining whether carbon in cast iron with graphite precipitation. Ensure adding good inoculant humectant and sufficient time. Once again, the problem of cooling. The cooling can not be too fast, easy fast cooling to produce white tissue.
Q:How to properly maintain FRP pipes
Light weightThe weight of the pipe is only 1/4 of the same size and the same length as the ductile iron pipe, and 1/10 of the cement pipe. The transportation is easy to handle and easy to install.
Q:How can the ductile iron pipe be welded?
The nickel electrode cold welding, such as Z408
Q:Why does the cast iron pipe always run off when testing?
If the pipe is exposed for pressure test, you must add a pier, or else the fittings fly out. You are not surprised. At the same time, the pressure test before the ink tube to make full immersion bubble discharge clean, or a big easy gas pressure pipe explosion.
Q:Will the quality of ductile iron shrink?
I am a professional casting, I can certainly tell you what he said, there is no basis, you see, the concave is due to do not have a good time, where the hot metal supplement
Q:What is the difference between a PE fire hose and a ductile iron pipe?
Seamless steel pipe: a pipe with a hollow cross section, used as a conduit for transporting fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
