Product Description

YITAI is China manufacturer & supplier who mainly produces Oil Drilling Low Pressure Union with many years of experience. Hope to build business relationship with you.

An oil drilling low pressure union is a type of connector used in the oil and gas industry for joining and sealing low-pressure pipelines or equipment during drilling operations. It is specifically designed to withstand low pressure levels, typically ranging from a few hundred to a few thousand pounds per square inch (psi).


Similar to medium and high-pressure unions, a low pressure union consists of two male-ended threaded connections that can be screwed together to form a secure and leak-tight joint. The male ends are typically connected to the pipeline or equipment, and a gasket or sealing ring is placed between them to ensure a tight seal. The union can be easily disassembled and reassembled, making it convenient for maintenance or repairs.


Low pressure unions are commonly used in drilling operations for various purposes, such as connecting mud tanks, mud gas separators, shale shakers, and other equipment where lower pressure levels are involved. They provide a reliable and secure connection, allowing for the smooth flow of fluids while preventing leakages.


It’s important to note that the specific design and specifications of low pressure unions may vary depending on the manufacturer and the intended application. They are typically designed to meet industry standards and safety requirements to ensure proper functionality and integrity of the drilling system.
