A composite thread protector that will be practical under normal as well as frigid temperature conditions of usage is formed by deep drawing a seamless metal shell wall, using a threaded die to define a mold cavity with the metal shell wall, forming and setting a synthetic elastomeric shell wall within the mold cavity in an adhering assembled relation with and along the metal shell wall with threading that is complementary with threading of the die, removing the assembly by unscrewing it with respect to the threaded die, and subjecting the assembly to heat treatment to cure the elastomeric shell wall and provide a composite protector having a cast urethane elastomer wall in a secure adhering encapsulating relation on the metal shell wall.

Compressed gas pipe thread sealant is a leak proof sealant for high pressure threaded pipe joints. It is a thick white liquid that seals compressed gas pipe or fittings threads to prevent leaks. It is brushed onto pipe threads before assembly to help prevent leaks. It fills thread imperfections or gaps and then cures into a tough elastic solid. It is ideal for use in vacuum systems, valve threads, natural gas, compressed air lines, refrigeration systems and bottled welding gases.

Subsea production control system is used to control and monitor subsea X-mas trees, downhole equipment and manifolds as well as subsea processing stations. There are two types of control systems such as electric and direct hydraulic control systems. An electro hydraulic control system consists of topside located computer system from which daily operation may be performed and where the safety system is interfaced. The subsea control module is the main part of subsea control systems. It contains electronics, instrumentation and hydraulics for safe and efficient operation of subsea and downhole valves. The SCM provides interfaces for communication with the topside system via the control umbilical and for downhole and subsea located instrumentation for production process monitoring and optimization.

A control umbilical is used to connect topside equipment to subsea equipment. These are also used for control and operation of subsea production, subsea processing and subsea injection facilities. The control umbilical consists of hydraulic lines used for transfer of chemicals and fluids. In addition, electrical and fibre optical components used to monitor pressure, temperature, flow, vibrations are part of the construction. The type of umbilicals varies according to field requirements and the umbilicals may carry different chemical injection lines, hydraulic supply lines and electric cables and/or fiber optic lines.

Conventional Cementing Plugs are made of an aluminum or plastic core and a finned outer shell made of rubber. Conventional cementing plugs are capable of accommodating considerable variation in the internal diameter of the casing string.
