Lightweight; It has excellent corrosion resistance. Threaded connection, easy to install. Good mechanical and physical properties. Long lifespan—designed to last at least 20 years. High-pressure resistance performance: Normal operating pressure ranges from 3.5 to 35 MPa. The medium flows easily, with no scaling, wax buildup, or tendency to clog. Excellent high-temperature performance: It can operate reliably at normal temperatures up to 80°C, fully meeting the requirements of oil extraction and water injection processes. -
