What is an Internal Thread Seamless Steel Pipe?

As a steel pipe product with a special structure, internal threaded steel pipe has an irreplaceable and important position in industrial heat exchange, petrochemical equipment, air conditioning systems and energy engineering. Its inner wall is made into a spiral or corrugated thread structure through mechanical processing or forming process. This design greatly increases the effective contact area of the inner wall of the pipe, and has significant advantages in enhancing heat transfer, disturbing fluid, improving mass transfer and improving system efficiency. With the development of industrial technology, the performance requirements for internal threaded steel pipes are increasing, and the selection of its specification parameters has become more and more critical. Understanding and mastering its detailed specifications is of great significance to ensure stable, safe and efficient operation of equipment.

Hollow Structural Sections (HSS) vs Traditional Steel Tubing(TS)

For many people, the terms Hollow Structural Section (HSS) and Tube Steel (TS) may sound interchangeable. After all, both refer to steel tubes with square, rectangular, or round cross-sections, right?Well, not quite.Although the terms are sometimes used interchangeably in casual conversation, they refer to distinct categories in the steel industry — each with its own standards, applications, and manufacturing specifications. Understanding the differences between HSS and traditional steel tubing (TS) is essential for engineers, fabricators, and contractors when selecting the right material for a project.

Comprehensive Guide to API 5L LSAW Steel Pipes

In modern pipeline engineering, API 5L LSAW steel pipe is an indispensable material. It is not only strong and durable, but also designed to cope with high-intensity and high-pressure environments such as oil and natural gas transportation and urban water supply. LSAW means "longitudinal double-sided submerged arc welding". This welding method ensures that the weld of the steel pipe is uniform and dense, can operate stably for a long time, and is not prone to leakage or rupture. In addition, this type of steel pipe also complies with the API 5L international standard, which means that its material, size, tolerance and performance have been strictly tested and can be safely used in various key projects, such as inter-provincial oil pipelines, natural gas trunk lines, water supply channels at water sources, etc.

LSAW Steel Pipe Forming UOE vs JCOE Methods Explained

The straight seam submerged arc welded steel pipes (LSAW Pipe) for oil pipeline engineering are generally manufactured by UOE and JCOE. The conventional production process is that after the steel pipe blank is formed by UO or JCO, it is pre-welded, internal and external final welded, expanded, non-destructive tested, pipe end processed, hydraulic pressure tested, weighed and measured, and visually inspected for steel pipe markings. Let's learn about the characteristics of the two processes of UOE and JCOE today!

How to Maintain Stainless Steel Structural Pipe?

Stainless steel structural pipes are strong and durable, not easy to rust, and look very textured, so they are often used in construction, machinery, food processing and other industries. However, no matter how good the material is, it is not omnipotent. If it is neglected for a long time, its surface may become dark, spotted, or even corroded. If you want it to keep its brightness, stable performance, and last longer, daily cleaning and maintenance are very important. Whether you use it indoors or outdoors in the wind and sun, this easy-to-understand maintenance guide can help you easily handle the daily maintenance of stainless steel structural pipes.
