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.

The Great Role Of API 5CT Oil Casing Pipe
API 5CT oil casing plays a vital role in oil well operations. These oil casings not only protect the drilling process from contamination of shallow water layers and shallow gases, but also support the production and drilling process of oil and gas wells. At the same time, the oil casing can also bear the weight of the wellhead and various layers of underground rocks to prevent the wellhead from collapsing. The existence of API 5CT casing ensures the smooth progress of drilling work, ensures the efficient operation of the entire oil well after completion, and can transport oil and gas from underground to the surface. This article will introduce some of the key functions and the importance of API 5CT oil casing pipes.

Requirements For The Inner And Outer Surfaces Of Oil Casing Pipe
The requirements for the inner and outer surfaces of an oil casing pipe are essential to ensure the integrity and performance of the casing in oil and gas drilling and production operations. These requirements are typically specified by industry standards and regulations and can vary depending on factors such as the well's depth, formation conditions, and the specific purpose of the casing. Here are some key requirements for both the inner and outer surfaces of oil casing pipes.
