- This article describes the history of pipeline development and common pipeline types and their characteristics, due to the development of HDPE pipelines, followed by the birth and development of butt welders
Humans have a long history of using pipes, with the Indus Valley Civilisation having standardised earthen pipes as early as 2700 BCE.China has also discovered the country's earliest drainage pipes at the 4,300-year-old Longshan culture site in Huaiyang
Modern pipeline transport in the true sense of the word has a history of just over 130 years worldwide, and it has only been undergoing significant development for 50 years.
Compared with railways, roads, airways, waterways and other modes of transport, pipeline transport has the characteristics of low cost, large capacity, small area, short construction period and high degree of automation, so it plays a very important role.
Pipeline can not only transport oil, water, natural gas, gas such as gas, liquid, but also transport municipal waste, industrial raw materials, food such as solid bulk materials.
Early transport pipelines were mainly made of concrete and metal materials. Concrete has good resistance to permeability, but it is self-sustaining, brittle and prone to damage along with land settlement.
The metal pipeline mainly cast iron and stainless steel, cast iron pipeline pressure resistance is weak, and easy to rust; and stainless steel pipeline cost is high, the material is hard on-site processing difficulties.
Plastic pipes, especially HDPE, are low-cost, corrosion-resistant, non-leakage, lightweight and easy to construct.
Europe and the United States developed countries welding plastic pipes from the 1950s, especially in the 1990s to get rapid development, in order to be able to better weld plastic pipes, heat fusion butt welding machine operation and birth.
Although the early hot melt butt welding machine has the basic features of the contemporary butt welding machine, but there are still some shortcomings such as uneven cutting edges and imprecise temperature control of the heating plate.
Nowadays, Welping has improved on the previous generation of heat fusion butt welding machine, the quality has been perfected, and in order to respond to the needs of different customers, developed, fully automatic, semi-automatic, manual butt welding machine in various forms. We have a wide range of sizes and grades.
Now, China has built 395 ultra-long transport pipelines totalling 17,000 kilometres, while pipeline laying is in full swing worldwide, making this a very promising industry!
