Lifting Subs are of one-piece construction and manufactured from alloy steel fully heat-treated. The structure includes sloping shoulder and straight shoulder, which can be selected by customs. Lifting Subs are normally manufactured 1200mm long overall. But this type sub can be made to any length desired.
1.API standard drilling cross-over sub 2.BOX x BOX, BOX x PIN, PIN x PIN 3.Different API Standard connection type, e.g. NC, REG, FH, IF etc. 4.Apply to HDD, Geothermal, Gas, Oil and Water well drilling.
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.

Additional functions of christmas tree include pressure relief, chemical injection, a conduit for control systems to monitor and control safety valves in down-hole For price,specification etc please contact us
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.
