Swivel Elbow
Using a double ball structure (such as 30CrMo alloy steel), containing three ball lanes and steel balls, it can withstand 10,000-15,000 PSI high pressure and achieve 360° rotation.
Swivel Joint
Integrated mechanical seal components (such as PTFE + tungsten carbide), support the simultaneous transmission of hydraulic oil, mud, acid and other media.
Threaded Union
API 6A standard ACME thread is used and quickly tightened with the airfoil nut. The sealing surface roughness is less than 0.4μm to ensure no leakage under high pressure

The 304 stainless steel bellows expansion joint with non-metallic compensation is a core component in industrial pipeline systems, integrating high strength, corrosion resistance, and flexible compensation. Through the combined design of metallic and non-metallic materials, it effectively addresses issues such as pipeline displacement, vibration, and temperature differences, and is widely used in energy, chemical, and construction industries. When selecting, customized configuration based on operating parameters is required to ensure system safety and long-term stable operation.

High pressure self-tightening flange is a kind of high strength flange connection device that relies on medium pressure to realize self-sealing. Through special structural design, the internal pressure of the pipeline is converted into the attached pressure and tight force of the sealing surface, which can maintain reliable sealing under strict conditions such as high pressure, high temperature and vibration
