Casing and Tubing Steel Grade Color Codes Color codes for steel grades are used to identify different types of casing and tubing based on their strength and threading. Below is the translation of the color coding system for oilfield tubular goods: Steel Grade Color Coding Steel Grade Tubing and Coupling Connection H40 Manufacturer's choice of
Casing Steel Grades There are twenty different steel grades for oil and casing pipes, namely H40, J55, K55, M65, N80, L80, C90, T95, C95, P110, Q125. Different color codes and symbols are used to distinguish various steel grades and thread types of the oil and casing pipes. The two or three digits following the color

Explanation of Casing Connections in Petroleum Industry Connections are one of the most common parts in tools and also one of the hardest to distinguish. Understanding connections is crucial for tool technicians or supervisors. Without knowledge of connections, procuring materials, preparing for operations, and directing work would be impossible and could lead to significant issues.
### Development Status of the Oil Pipeline Market in 2024 #### Overview Oil pipelines are a critical component of the petroleum industry, serving as the primary means of transporting crude oil and natural gas from production sites to consumption centers. The development of the oil pipeline market is essential for the stable operation of the
The History of Oil Pipelines Since the late 19th century, after the British inventor Walker created concrete pipes, the pipeline industry began to develop, with oil pipelines standing out among them. Oil pipelines are a means of transporting petroleum products via pipelines, and their construction and development are closely related to advancements in the petroleum
Materials for Oil Pipelines Oil pipelines are a crucial method for transporting oil, and the selection of pipeline materials directly affects the safety and efficiency of oil transportation. When choosing materials for oil pipelines, multiple factors must be considered, such as the operating environment of the pipeline, the properties of the transported medium, design pressure,
A Brief Discussion on the Current Status and Methods of Oil Tube Cleaning Currently, both domestically and internationally, common methods for cleaning oil tubes can be divided into physical cleaning and chemical cleaning categories. These include heating cleaning, hot soaking, biocleaning, laser cleaning, dry ice cleaning, ultrasonic cleaning, and water jet cleaning, among others.
Overview and Usage Method of Oil Tubes Oil tubes are pipelines used to transport crude oil and natural gas from the oil and gas layers to the surface after drilling is completed. They are designed to withstand the pressure generated during extraction. I. Introduction to Oil Tubes Oil tubes are steel pipes commonly used
