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:What are the differences between ductile cast iron pipes and centrifugal ductile iron pipes?
Centrifugal casting is a casting method. Ball milling cast iron pipe is a kind of material.
Q:What are the differences between cast iron pipes W and A?
Type W: combination of both advantages of the connection type A interface has the advantages of high strength and convenient installation, because of the use of W type straight pipe and reduces the material cost and can be coupled with the design structure of the B type pipe is more compact than the A type pipe, saving installation space.
Q:When the ductile iron pipe is pressed, the three links are always running out. What should be done?
If the conventional backfill soil pressure, pipe fittings installed properly, the phenomenon will not appear.
Q:How much is the installation fee of the 400 largest ductile iron pipe?
From the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve greater runoff; from the installation and maintenance cost, ductile pipe have more favorable price. The inner wall of zinc spray, anti-corrosion materials such as cement mortar.
Q:Principles for the antiseptic treatment of ductile iron pipes
Anti corrosion process of ductile iron pipe:1. asphalt paint coatingBituminous paint coatings are pipes used to carry gas. Preheating the pipe before spraying can improve the adhesion of asphalt paint and accelerate drying.2. cement mortar lining + special coatingThe internal corrosion prevention measures are suitable for pipes conveying sewage, and the corrosion resistance of lining can be improved.3. epoxy coal tar coatingThe epoxy coal tar coating is not only suitable for gas pipelines, but also for sewage pipes. It is a two component coating with a high adhesion and a very smooth surface
Q:General cast iron prices now
Hubei, Suizhou, in 2010, normally 5000-7000 tons of iron, if required to join copper and other metals, the price is calculated. The price is very low, because the market price in Suizhou is the lowest in the whole country. Under normal circumstances, it should be 8000 tons a ton
Q:QT400-10 nodular cast iron requires hardness of HRC47~51. Why can't quench hardness be reached?
Quenching temperature: when the silicon content of nodular cast iron is 2.0-3.0%, the quenching temperature is 860-900 DEG C, the silicon content is low, and the upper limit is taken when the lower limit is high.2. holding time: because of the consideration of diffusion graphite cast iron, alloy steel is therefore the holding time, holding time longer than carbon steel.3. oil quenching.
Q:How can the ductile iron pipes be treated with corrosion protection?
Bituminous paint coatingBituminous paint coatings are pipes used to carry gas. Preheating the pipe before spraying can improve the adhesion of asphalt paint and accelerate drying
Q:The difference between spheroidal graphite cast iron pipe and HDPE water supply pipe
HDPE pipe is made of hot melt butt joint, and the strength of interface is very good. Ductile iron pipes are made of socket joint, and reinforced concrete piers shall be rammed on three links, elbows and other parts. In this regard, the cost of natural selection of ductile iron pipe, HDPE pipe than the choice of high.
Q:Is ductile iron pipe breakable?
5, inferior wood surface is easy to produce cracks, because its billet is adobe, Adobe porous, Adobe in the process of cooling due to the role of thermal stress, cracks, after rolling, there are cracks;6, poor drainage tube appearance often pitted phenomenon. Pits is due to groove wear caused by defects in pipe surface irregular uneven. Because of the poor sewer pipe manufacturers to pursue profits, often rolling groove rolling most standard.Ductile iron pipes are broken because of the excessive heat treatment during casting or the lack of proper addition in casting to prevent a change in the proper brittleness and to cause cracking. It is recommended that you used to repair defects of cast iron machine, are currently on the market to sell, but also can ensure welding intact appearance, make your products by quality, but if it is in the use of performance can not meet the effect, especially the pipeline pressure quite big, what methods are of no use that must be re cast as the new.
