Product Description:

Oilfield Couplings - High Performance Couplings for Oilfield Operations

Oilfield Couplings are essential components for the seamless connection and joining of pipes used in oil and gas drilling, production, and transportation. These couplings are designed to withstand high pressure and harsh environments, ensuring a secure and reliable connection between pipes.

  • High Pressure: Oilfield Couplings are built to withstand high pressure, making them suitable for use in a wide range of oilfield operations.
  • Corrosion Resistance: The couplings are made from high-quality materials that are resistant to corrosion, ensuring long-lasting performance in harsh and corrosive environments.
  • Easy Installation: The seamless design of these couplings allows for quick and easy installation, reducing downtime and increasing efficiency.
Manufacturing Type

Oilfield Couplings are manufactured using advanced techniques and equipment to ensure high quality and precision. The manufacturing process involves seamless production, resulting in strong and durable couplings that can withstand extreme conditions.

Connection Types

Oilfield Couplings come in various connection types to meet different application requirements. The most common types include threaded, welded, and flanged connections.

Threaded Connections

Oilfield Couplings with threaded connections are designed to be screwed onto the ends of pipes, creating a secure and leak-proof connection. The most commonly used thread types are API, NPT, and BSP.

Welded Connections

Welded connections involve joining the ends of pipes using heat and pressure to create a permanent bond. This type of connection is ideal for high-pressure applications and can withstand extreme temperatures and harsh environments.

Flanged Connections

Flanged connections involve the use of flanges and bolts to connect pipes. This type of connection is commonly used in applications where frequent disconnection and reconnection of pipes is required.


All Oilfield Couplings meet the industry standards set by API 5CT, ensuring high-quality and reliable performance. These standards cover the design, materials, and testing requirements for couplings used in oil and gas operations.

Oilfield Couplings are essential components for the smooth and efficient operation of oil and gas activities. With their high pressure and corrosion resistance, easy installation, and various connection types, these couplings are a reliable choice for any oilfield operation. Trust in Oilfield Couplings for a secure and long-lasting connection between your pipes.

Oilfield Couplings - The Perfect Solution for Oil and Gas Industry
Brand Name: SWS | Place of Origin: China | Surface Treatment: Zinc Plating, Hot Dipped Galvanized | Connection Type: Threaded, Welded, Flanged | Standards: API 5CT

Oilfield Couplings, also known as Oilfield Casing Couplings, are essential components used in the oil and gas industry. These couplings are designed to connect two pipes or casing tubes together in a secure and leak-proof manner, ensuring smooth and efficient oil and gas operations. SWS, a trusted brand from China, offers high-quality Oilfield Couplings that meet the industry standards and requirements.

Application in the Oil and Gas Industry

Oilfield Couplings have a wide range of applications in the oil and gas industry. They are used in drilling, completion, and production stages of oil and gas operations. These couplings are used to connect casing strings, drill pipes, and tubing strings, providing a secure and reliable connection. They are also used in wellhead equipment, such as blowout preventers, to connect the wellhead with the casing strings.

Surface Treatment for Durability

SWS Oilfield Couplings are available in two surface treatments - Zinc Plating and Hot Dipped Galvanized. Zinc plating provides a thin protective layer of zinc on the surface of the coupling, preventing corrosion and increasing its lifespan. Hot dipped galvanization, on the other hand, involves immersing the coupling in molten zinc, resulting in a thicker and more durable protective layer.

Various Connection Types

SWS Oilfield Couplings come in three different connection types - Threaded, Welded, and Flanged. Threaded couplings have threads on both ends, allowing for easy and quick connection without the need for welding. Welded couplings are welded to the pipes, providing a strong and leak-proof connection. Flanged couplings have flanges on both ends, which are bolted together to form a secure connection.

Inspection and Standards

Quality is of utmost importance in the oil and gas industry, and SWS Oilfield Couplings adhere to the industry standards. These couplings undergo Non-Destructive Testing (NDT) as per API 5CT and 5B standards, ensuring that they meet the required specifications. This inspection process ensures that the couplings are free from any defects and are safe to use in oil and gas operations.

In conclusion, SWS Oilfield Couplings are an essential and reliable solution for the oil and gas industry. With their durability, various connection types, and adherence to industry standards, they provide a secure and efficient connection for pipes and casing tubes. Choose SWS Oilfield Couplings for your next oil and gas project and experience seamless operations.
