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 is the excavation width of ductile iron pipes with diameters greater than 1400?
When the condition does not allow enough slope, it is necessary to do wall protection and other means to ensure safetyRemind me, such a big pipe, dig deep in two ways. One is the depth diameter (range at the junction of 1.6 m in length and 500 for manholes and operation. The lower bolt assembly when) there is a depth diameter plus 500. and then in the trench laying branch the pier, installed after the fine stone tamped backfill.Can also be buried directly with the pipe diameter, and then put into the assembly. This method requires a large space on the ground, otherwise, the volume is too large after assembly, weight is too heavy, may cause damage to the pipeline and personnel injuries
Q:Ductile iron pipes perennial bubbles in the water will rot it
Ductile iron pipes mainly called centrifugal ductile iron pipe, it has the properties of nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
Q:How can the steel plastic composite pipe be connected with the cast iron pipe?
Use stainless steel clamps to connect.
Q:Can ductile iron pipes be installed outdoors?
Ductile iron pipes can be installed outdoors.
Q:What quota can be used for the installation of DN300 ductile iron pipes?
Ductile iron is a kind of high strength cast iron material developed in 50s twentieth Century, its comprehensive performance is close to the steel, it is based on its excellent performance, has been successfully used in casting complex stress, strength, toughness and wear resistance requirements of the higher parts. Nodular cast iron has developed rapidly to be second only to grey cast iron and widely used as cast iron material. The so-called "iron instead of steel", mainly refers to ductile iron.
Q:What if the ductile iron pipe is broken?
Ductile cast iron pipes are broken because of the excessive heat treatment during casting or the lack of proper addition in casting to prevent the proper change of the proper brittleness and cause the rupture to be effective.
Q:How many casting methods are there in ductile iron casting? A 60*6 discus can not have sand holes. Its surface is smooth. What process can be used to make it?
This is such a small piece, do not worry about shrinkage, mainly pay attention to sand hole and slag. With Disa wet molding line, a box of more pieces, suitable for mass production, defects will be relatively less. By using other methods (resin sand coated sand, etc.) can also be the main attention, don't type it, then the level of liquidity and relatively ductile iron, gray iron poor, sand and gas can not go up, sand holes or pores will spread in the discus plane.
Q:How can the ductile iron pipes be treated with corrosion protection?
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:What is the K9 standard pressure for ductile iron pipes?
Ductile iron pipe is a kind of cast iron. It is an alloy of iron, carbon and silicon. Graphite is exist in spherical form, usually graphite size is 6-7, casting spheroidization grade control requirements for 1-3 quality (spheroidization rate greater than 80%), so the mechanical properties of the material itself has been improved, has the essence of iron, steel performance.
Q:What is the difference between cast iron pipe and seamless steel pipe and galvanized steel pipe?
Galvanized steel pipe: divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, and the latter is also advocated by the state for the time being. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned. China's Ministry of construction and other four ministries also issued a civilization, indeed from two, 000 years since the galvanized pipe as a water supply pipe, the New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe. Hot dip galvanized steel pipe is widely used in fire, power and highway.
