Drill Pipe Sub

1.It is divided into drill string crossover and tubing Crossover. 2.Drill string Cross-over is divided into type A, type B and type C. Crossover subs are made from AISI41455H chrome molybdenum alloy steel, and the content of micro-element can be controlled availably. The surface of sub threads are phosphated or copperized. According to shapes and applications, crossover subs are divided into three types: Type a stands for the same diameter: one crossover sub has one size. Type b stands for reduce type: one crossover sub has two sizes. Type c for left hand thread type: the connection thread is left hand type. Use: it plays a role of connectivity and conversion in different specifications drilling tools. Characters: crossover subs are complied with SY5200-93 or API Spec7. All products must be ultrasonic nondestructive tested and the surface copper coated. Crossover subs of various types and lengths are available.

The pipe body is in conformance in API 5DP with serious inspection in plant. Tool Joints are made of AISI4137 premium alloy steel fully Q and T with IPSEN furnace. All tool joints should be inspected at full length by fluorescence magnetic particle and ultrasonic method.

Kelly is the drive part of whole drill stem, it has two types, square kelly and hexagonal kelly and all of them are manufactured comfort to API Spec7-1 and SY/T6509-2000 criterion. Our� Square& Hexagonal kelly are made from AISI 4145H modified alloy bars that are quenched and tempered full length. After such heat treatment, its brinell hardness can reach 285-341. Kelly end, drive cross-section and joint are all processed and tested comform to API criterion.

The six-party drill pipe is made from AISI4145HMOD alloy steel According to API Spec.7 -1. IT is formed by hot forged and fully heat-treated by intermediate frequency induction heat treatment or 20m horizontal optical resistance furnace to threads are phosphated, copperrized or cold worked.   Standard size of hexagonal kelly;Each can reach a total length of 27 meters.

Drill subs are an important integral part of everyday drilling. Not having the right thread adapter can make your life miserable. We have a large inventory of common and not so common sizes. Custom sizes are always available. Rotary subs have two primary applications. They can be used to cross over from one connection size to another, or as the disposable component used to extend the connection life of a more expensive drill stem member. Installing a float sub (with check valve) is always a good idea when drilling in wet situations.
