Seamless Fluid Service Pipe is a hot-rolled or cold-drawn seamless steel tube designed specifically for liquid, gas and fluid transportation. With no welding seam, integrated tubular structure, high pressure resistance and excellent airtightness, it ensures zero leakage during fluid delivery. It is the most reliable steel pipe for industrial fluid conveying, water supply, oil and gas pipeline systems.
