Here's an overview of the ultrasonic flaw detection standard of straight seam steel pipe.

In the production process, since the actual size is difficult to achieve the nominal size requirement, that is, it is often larger or smaller than the nominal size, the standard specifies that a difference is allowed between the actual size and the nominal size. This article will introduce briefly the API SSAW steel pipe tolerances.

Seamless steel pipes are categorized under various HS codes, reflecting their specific characteristics and applications. Below are some key HS codes for seamless steel pipes and hollow profiles.

Seamless steel pipes are classified based on their ability to withstand different pressure levels. This classification is crucial for selecting the appropriate pipe for various industrial applications. The pressure ratings for seamless steel pipes are categorized as follows.

Polishing methods for seamless steel tubes include mechanical polishing, chemical polishing, and electrochemical polishing. Each method has its own advantages and disadvantages, and the choice of method depends on the specific requirements and constraints of the task at hand.

This article will briefly introduce GB standard for seamless steel pipe.

The production process of SSAW (Spiral Submerged Arc Welding) steel pipes affects the quality of single-side welding and double-side welding primarily through factors such as welding current, welding speed, number of welding layers, electrode type, and electrode diameter.

Understanding and selecting the right piercing tool is vital for producing seamless steel pipes efficiently and with high quality. The primary components of the piercing tool are as follows.

API 5L X52 seamless pipes are critical components in the oil and gas industry, and their quality and precision are paramount. Below are the detailed requirements and size tolerances for these pipes.

During the loading and unloading of spiral steel pipes, some damage is inevitable. However, taking certain measures can minimize this damage and ensure the integrity of the pipes. The details are as follows.

Metallographic analysis of seamless steel tubes is crucial for assessing their internal structure and identifying any potential defects. This analysis is typically divided into high magnification and low magnification tests, each serving different purposes and providing various insights into the material's properties.

The delivery conditions of seamless steel pipes refer to their state following the final plastic deformation or heat treatment. These tubes can be delivered in different states, each with distinct characteristics based on the manufacturing and processing techniques used.
