The history of interlocked pipes


Today, with the advancement of industry and technology, interlocked pipes can meet all these requirements. Due to its high strength and shock resistance, interlocked pipe can be used as a highly reliable foundation. Therefore, they are widely used as foundation piles for civil engineering and construction engineering.

What are the development areas of interlocked pipes?

With the development of reform and opening up and economic construction, interlocked pipes began to be widely used in railway systems, and expanded to industrial and civil buildings, municipal administration, metallurgy, ports, highways and other fields.

In the Yangtze River Delta and the Pearl River Delta, due to the geological conditions suitable for the characteristics of interlocked pipes, the demand for interlocking pipes has surged, and new industries have rapidly formed.


What is the development history of interlocked pipes?

In the past two decades of development, the pipe pile project has won the second prize of scientific and technological progress in the building materials industry and the third prize of national scientific and technological progress; the pipe pile has been listed as a national new product and a key new product by the Ministry of Construction.


In 2006, with the joint efforts of relevant units and associations, the interlocked pipe products of Zhongshan Jianhua Pipe Pile Co., Ltd., Guangdong Sanhe Pipe Pile Co., Ltd., and Ningbo Zhendong Building Materials Group were selected. The catalogue of China's famous brand products is another new upsurge in the development of China's pipe pile industry, which has received unanimous praise from both inside and outside the industry.


What are the impacts of the development of interlocked pipes on various industries?

According to incomplete statistics, by the end of 2007, there were more than 400 pipe pile manufacturers (excluding those in Taiwan), producing 250 million meters of various pipe piles, and the output value exceeded 30 billion yuan. At the same time, the annual output value of auxiliary products of the supporting interlocking pipe industry is nearly 25 billion yuan, which has become a vibrant emerging industry. Pipe piles have accounted for about 50% of the total output value of the national cement product industry.

Sunley's unique offshore engineering research center in China has laid a solid foundation for the production process. While ensuring the performance of interlocked pipes, we design and provide customers with optimized solutions to save costs by saving the amount of steel. Therefore, Shunli's interlocked pipes are widely used in breakwaters, deep foundation pit excavation, integrated pipelines, tunnels, subways, bridges and tunnel projects.


A sound quality assurance system is the cornerstone of Shunli's global expansion. It is these globally-recognized certifications, such as API, FPC, CE, ISO9001, ISO14001, EN1090, and strict quality assurance system that make every bunch of products produced by Jiangsu Shunli Steel Pipe Group become customer-certified products.
