What Are The Functions Of Slotted Casing?
Slotted casing, also known as slotted pipe or slotted liner, is a specialized type of casing used in well construction for oil and gas, water wells, and various underground applications. It is designed with openings or slots cut into the pipe wall to allow the flow of fluids and gases between the exterior and interior of the casing. Today, Union Steel Industry will talk about several important functions of slotted casing in well construction.

API Oil Casing Special Thread
At present, oil well pipes (oil pipes, oil casing pipes, and drill pipes) are basically implemented in accordance with API (American Petroleum Institute) standards. However, API casing threads are not suitable for the development of high-pressure gas fields, so many manufacturers have developed special joints with their own characteristics and are protected by patents. Today, Union Steel Industry will introduce some common special thread types for oil casing.

Heat Treatment Of Oil Casing
Heat treatment of oil casing is a process that improves the physical and mechanical properties of the casing by controlling its temperature and cooling rate to meet the requirements of a specific application. Oil casing typically undergoes two main types of heat treatments: normalizing and tempering. These heat treatments adjust the hardness, strength, corrosion resistance and toughness of the casing, making it suitable for drilling, producing and transporting oil and gas. The following are the general steps and purposes of heat treatment of oil casing.
