Oilfield Couplings

Oilfield Couplings are essential components in oil and gas drilling operations. These couplings connect sections of oilfield pipes together, allowing for the efficient transport of oil and gas from the well to the surface. Our Oilfield Couplings are designed to withstand the harsh conditions of the oilfield and provide a reliable and secure connection.

Product Overview

Our Oilfield Couplings come in three different Thread Buckle Types: BTC (Buttress Thread Coupling), STC (Short Thread Coupling), and LTC (Long Thread Coupling). These Thread Buckle Types are designed to fit different types of oilfield pipes and provide a tight and secure connection.

The material used for our Oilfield Couplings is Carbon Steel, known for its strength and durability. This ensures that our couplings can withstand the high-pressure and rough environment of oil and gas drilling operations.

Our Oilfield Couplings meet the standards set by the American Petroleum Institute (API), specifically API 5CT. This means that our couplings have been tested and certified to meet the industry's strict requirements for quality and performance.

Manufactured through a seamless process, our Oilfield Couplings are made from a single piece of steel, ensuring a strong and seamless connection. This also reduces the risk of leaks and enhances the overall integrity of the oilfield pipe.

Our couplings come in various Thread Types, including API (American Petroleum Institute), NPT (National Pipe Thread), and BSP (British Standard Pipe). These Thread Types provide compatibility with different types of oilfield pipes and allow for easy installation and removal.
