Definition and purpose of pipeline pipe:
Pipeline pipes are pipelines used for transporting oil, gas, or water, including seamless and welded pipes. The pipe ends can be flat, threaded, or socket. There are various connection methods, including end welding, clamp connection, socket connection, etc.
Technical specifications:
The specification range of pipeline pipes is 10.3-2032 × 1.7-39.7mm, and the execution standard is GB/T9711.1/API SPEC 5L. It is mainly used for gas, water, and oil transportation in the natural gas industry.
Material selection:
In API SPEC 5L-2011 specification, the main materials for pipeline pipes include L245, L290, L360, L415, L480, and GR B. X42, X46, X56, X65, X70, X80, X100 and other steel grades.
Tempering type:
According to the different performance requirements of GB/T9711.1 pipeline steel pipes, tempering can be divided into low-temperature tempering (150-250 degrees) and medium temperature tempering (250-500 degrees) based on their different tempering temperatures.
Progress in Basic Research on High Grade Pipeline Steel and Steel Pipe Applications:
China has made significant progress in basic research on the application of high-grade pipeline steel and steel pipes. We have independently developed the X70/X80 series hot-rolled coil and large-diameter thick walled spiral submerged arc welded pipe manufacturing technology, and have preliminarily completed the development of X90 pipeline steel and steel pipes.
Pipeline modeling and generation:
3D pipelines can be divided into two types based on their cross-sectional shape: square pipes and circular pipes. The 3D construction of these two types of pipelines can be achieved using the BOX and Cylinder methods in Skyline.
Technical Specification for Urban Underground Comprehensive Pipe Gallery Pipeline Engineering:
The regulations cover multiple aspects such as thermal pipelines, power cables, communication cables, etc., providing detailed technical guidance for urban underground comprehensive pipe gallery pipeline projects.
Basic knowledge of underground pipelines:
The underground pipeline structure includes the water supply pipeline structure, and its characteristics and technical terms such as pressure pipelines, gravity flow pipelines, and bendable pipelines are elaborated in detail.
Principles, specifications, and spacing requirements for comprehensive pipeline layout:
The principles and specifications for the comprehensive layout of pipelines include prioritizing large pipes, giving way to non pressure pipes for pressure pipes, and avoiding high-pressure pipes for low-pressure pipes, as well as the treatment of holes in the post pouring plate area in the structural specialty.
