Ductile iron pipe has the nature of the iron and steel property. The ductile, refers to the arrangement is spherical graphite in cast iron components, to weaken the body and cause stress concentration effect is very small, so with excellent toughness. Nodular cast iron, also has a high strength, high elongation and corrosion resistance. Easy to install, and other characteristics. Widely used in petroleum, electric power, chemical, and water transportation and gas pipeline engineering.

Tubing & Casing Coupling
Coupling is the joining of two short length pipes by the means of male and female threads.
All types of couplings have internal threads which are known as female thread forms. These thread forms are usually machined so that they can be coupled with the external threads on pipes known as male thread forms. Couplings are strictly designed as per API specifications.
There are two types of tubing couplings widely used in the pipeline coupling manufacturing industries namely:
Non-upset Thread Tubing Coupling
External-upset Thread Tubing Coupling
