Frequently Asked Questions (FAQs)

What is the difference between seamless and welded steel pipes produced in China?

?

When it comes to steel pipes from China, you need to know the key differences between seamless and welded pipes. Seamless pipes are made from a round steel billet through processes like hot rolling, cold rolling, or cold drawing, resulting in a pipe with no seam. In contrast, welded pipes are manufactured from flat steel plates or strips that are bent and welded into shape. Seamless pipes have better pressure capacity and are often used in high-pressure equipment and industrial pipelines, while welded pipes are more cost-effective and used in industries like aerospace and automotive.

What are the common raw materials used for seamless steel pipes in Chinese factories?

?

For seamless steel pipes, Chinese factories typically use steel billets or solid tubes as raw materials. These billets can be made from carbon structural steel, low alloy structural steel, alloy structural steel, or even stainless steel. The billet is then perforated and formed through various processes like hot rolling, cold rolling, or cold drawing to create the seamless pipe.

What are the size limitations for seamless steel pipes produced in China?

?

If you’re looking for seamless steel pipes from China, you should know about the size limitations. Most Chinese manufacturers produce seamless pipes with a maximum outer diameter (OD) of 20 inches (508 mm), and commonly, the sizes are smaller than 16 inches (406.4 mm) due to equipment limits. For larger sizes, hot expanding machining is used, but the quality may not match that of the original seamless pipes.

How do Chinese factories ensure the quality of their seamless steel pipes?

?

Quality is a top priority when it comes to seamless steel pipes from Chinese factories. To ensure quality, these pipes undergo rigorous testing, including 100% inspection before shipment. Additionally, third-party inspections are available, and mill certificates are provided with the shipment. The manufacturing process itself involves strict adherence to international standards like API 5L and ASTM, ensuring the pipes meet high performance and safety criteria.

What industries commonly use seamless steel pipes produced in China?

?

Seamless steel pipes from China are widely used in various industries due to their high strength and reliability. You’ll find them in applications such as line pipes for pipelines, thermal services, mechanical industries, and chemical industries. They are particularly favored in high-pressure equipment and boiler industries where the pipes are subjected to extreme thermal, chemical, and mechanical workloads.
