Oil pipe head four-way
10 month agoProduct Advantages
Good compatibility: Its size design allows it to perfectly match 13 5/8-inch casing and a variety of wellhead equipment, such as blowout preventers, tubing heads, Christmas trees, etc., ensuring the overall coordination and stability of the wellhead device, and facilitating flexible configuration and combination in different drilling and production operations.
High strength and durability: It is usually forged with high-quality high-strength alloy steel, such as 35CrMo, 42CrMo, etc. After strict heat treatment process, the spool has excellent strength and toughness, can withstand the high pressure and complex mechanical environment of the wellhead, effectively resist formation pressure, fluid erosion and various external forces during the mining process, and greatly extend its service life.
Reliable sealing performance: Equipped with advanced sealing structure and high-quality seals, such as metal-to-metal seals, rubber seals, etc., it can still ensure the sealing of various connection parts and channels under the high pressure and high temperature environment of the wellhead, effectively prevent the oil, gas, drilling fluid and other fluids in the well from leaking to the ground, and reduce the possibility of safety risks and environmental pollution.
Efficient fluid control: The internal channel is reasonably designed and adopts a smooth transition curve, which reduces the resistance and eddy current of fluid flow, so that drilling fluid, oil, gas and other fluids can flow and distribute smoothly in the four-way, improve the fluid delivery efficiency, help optimize the drilling and production operation process, and reduce energy consumption and cost.
Easy to install and maintain: Its connection method is simple and convenient, whether it is threaded connection or flange connection, it is easy to operate, and it can save time and labor costs when installed at the wellhead site. At the same time, the structural design of the four-way is convenient for disassembly and maintenance when necessary, and the replacement and overhaul of each component are relatively easy, reducing equipment downtime and maintenance difficulty.

Product Features
Specific size specifications: The nominal size is 13 5/8 inches. This size determines its adaptability and diameter size in the wellhead device, and is an important basis for its use with other equipment. At the same time, the overall appearance and connection dimensions of the four-way are strictly designed and manufactured in accordance with relevant standards to ensure accurate docking with other wellhead components.
Strict quality inspection: During the manufacturing process, strict quality inspection procedures must be carried out, including non-destructive testing, physical and chemical performance testing, sealing performance testing, etc., to ensure that every 13 5/8 casing spool shipped out of the factory meets the requirements of relevant standards and specifications, has reliable quality and performance, and provides strong guarantee for the safe operation of wellhead devices.
