Oil & Gas Well Drilling Spool For Wellhead Pressure Control Equipment
The Drilling spool is the part of wellhead pressure control equipment which is used to connect with bop for oilfield drilling work.The spool is made of alloy steel and heat-treated. It is used on the oil and gas well which is with a pressure of less than 105Mpa. It is tested according to ((SY/T5053.1-2000 BOP and control equipment, BOP)) before shipping to be used safely.
The drilling spool spool applies to drilling high pressure oil and gas well, the connecting of the by passage of the spool with the valves and pipes will play not only a role of blowout and choking , but also a role of connecting the BOP with the wellhead.
Installation and Maintenance of drilling spool
1. Being used when connecting with the BOP and the casing head.
2. The steel ring grove should be cleaned before installation.
3. Tighten studs averagely of connecting the spool with the BOP.
