Oil and gas pipeline measures 14 to 42 inches in diameter, but is usually 20 to 36 inches. It is often composed of 40-foot lengths but lengths may be as long as 60 or 80 feet. The pipe is wrapped and coated for protection against corrosion, especially since it runs underground. About half of all gas

Seamless steel pipe has a very important position in China's steel industry, the low-pressure boiler tubes and high pressure boiler tubes also plays a important role in the seamless steel pipe. Their application environments are relatively poor and have requirements on temperature and pressure , so
