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:Is it better to use steel tubes or ductile iron pipes for water supply?
Flexible seamless steel pipe is good toughness, good processing, better than ductile iron corrosion resistance, the price is slightly higher;
Q:Method for cutting large diameter ductile iron pipe
When the ratio of oxygen to acetylene is 1 to 1.2, the flame produced is called neutral flame, also known as normal flame. It consists of flame core, inner and outer flame: near the welding nozzle at the flame core, a bright white; followed by the flame, a blue purple, the highest temperature, about 3150 DEG C, from the front cone at 2 ~ 4mm, and the application of welding wire to the workpiece; the outer flame is orange red. Neutral flame is a flame commonly used in welding. It is used to weld low carbon steel, medium carbon steel, alloy steel, copper and aluminum alloy.
Q:How can the ductile iron pipe depress the elbow so as to prevent it from being opened?
The elbow is the pipe that changes the direction of the pipe. According to the angle, there are 45 degrees and 90 degrees, 180 degrees, three most commonly used, in addition, according to the project needs, including 60 degrees and other non normal angle elbow.
Q:Ductile cast iron can replace copper sleeve
Under dry friction conditions, we design a pre - formed synovial membrane on the surface of the bearing to ensure that the solid lubricant is transferred to the dual parts in the shortest possible time, and an effective solid lubricant film is formed
Q:Usage of ductile iron pipe expander
Ductile iron expansion is mainly provided with large flexible, easy installation, the product main material for nodular cast iron, nodular cast iron is mainly through spheroidization and inoculation by spherical graphite, effectively improve the mechanical properties of cast iron, especially the plasticity and toughness increased, resulting in higher than the strength of carbon steel. The material mainly has high strength of plasticity and toughness, and its development at home and abroad is very fast, the output has exceeded cast steel and malleable cast iron, become second only to gray cast iron casting alloy material. Spheroidal graphite is obtained by spheroidizing and inoculation of nodular cast iron. It can effectively improve the mechanical properties of cast iron, especially improve the plasticity and toughness, so as to obtain higher strength than carbon steel.
Q:The difference between cast iron pipe and ductile iron pipe
I don't understand your question! Both have spigot and socket connection type pipe material, also have flange,
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.
Q:Ductile iron gears are generally treated without heat treatment
The mechanical properties of ductile iron are equivalent to quenched and tempered steel. The gears made of ductile iron can be quenched or tempered by high temperature + surface quenching, that is, quenching and tempering treatment + surface hardening.
Q:How to choose a ductile cast iron pipe with guaranteed quality
Cutting testing: iron filing resistance, filing issued a "Shua" sound, little sticky file, debris was gray with a small amount of white spot, look at the particles of different size, with small particles of fine powder, finger milling, it is easy to make fingers black. Ductile iron filing: when the resistance ratio of gray iron is slightly larger, there are obvious "Shua" sound ", little sticky file, debris was gray with fine bright particles ranging in size but with large particles, with finger milling chips, can be dyed black to gray fingers, but more black the degree of light
Q:What is the exterior anticorrosion of nodular cast iron pipes?
First clean the impurity on the surface of the pipe or fitting, and then sprayed zinc treatment (130g/m and asphalt paint coating fand) not less than 70 m
