China Slotted Casing: Types and Heat Resistant Grades
China Slotted Casing is a type of steel pipe used in oil and gas drilling. It is designed with vertical slots cut into the wall of the casing to allow oil and gas to flow into the wellbore. The slots can be cut into a wide variety of shapes and sizes depending on the specific drilling requirements. There are many types of China Slotted Casing available, including: 1. Perforated Slotted Casing 2. B
There are many types of China Slotted Casing available, including:
1. Perforated Slotted Casing
2. Bridge Slotted Casing
3. Wire Wrapped Slotted Casing
Perforated Slotted Casing is the most common type and is made by punching holes in the casing wall. Bridge Slotted Casing is made by cutting slots into the casing and then welding a bridge across the slot. Wire Wrapped Slotted Casing is made by wrapping a wire around the casing and then cutting the slots into the wire.
China Slotted Casing is also available in different heat resistant grades, which are designed to withstand the high temperatures and pressures of oil and gas drilling. The most common heat resistant grades are:
J55 and K55 are lower grade heat resistant casings, while N80 and L80 are medium grade. C90, T95, and P110 are high grade heat resistant casings. The higher the grade, the more resistant it is to heat and pressure.
In conclusion, China Slotted Casing is an important tool for oil and gas drilling. It is available in different types and heat resistant grades to suit various drilling requirements. Understanding the different types and heat resistant grades can ensure that the right casing is chosen for the job.
