Casing head is a kind of part connecting casings and wellheads.It is used as supporting the weight of technical casing and production casing, sealing the annular space between the casings, and installing BOP stacks. It provides a transition joint for the tubing head,Christmas tree and other wellheads.It can also supply cement monitor &control well’s sinking and inject balance liquids etc by the two side outlets on the casing head housing.
Material Class: AA~FF
Vertical Bore:178 mm ~ 318mm
Connecting casing(O/D): 7 5/8” ~ 13 3/8”
Working Pressure: 2000~20000psi
Product Specification Level: PSL1 ~ PSL4
Performance Requirement: PR1,PR2
Main features:
The casing head manufactured by us is a standard structure,the casing hanger produced fits well with the casing housing and the casing hanger of different sizes are available according to the casing procedure and the change of well head conditions.The standard casing head's top connection is API 6B or API6BX flange.
The options of the casing head as follows:
· The bottom connection of the casing head is either APl round box thread or APl buttress box thread; it can also be slip type connection.
·it can be provided with weld supporting base plate
·Side outlets could be pipe line thread or studded.studded side outlet is machined with female thread for connecting R11/2 reversing valve.
