In the bustling world of oil and gas extraction, every component plays a crucial role in ensuring efficient and safe operations. One such component, often overlooked but vital, is the gland.
What is a Gland?
A gland, in the context of oil and gas, refers to a seal around a moving rod, typically a piston rod or valve stem. This seal is essential for preventing leakage of fluid or gas from the system while allowing the rod to move freely.
Types of Glands:
Glands can be broadly categorized into two types:
Functions of a Gland:
Importance in Oil & Gas Operations:
Glands are crucial components in various oil and gas operations, including:
