application
- Used for permanent terminal closure of piping systems to achieve absolute sealing of high-pressure fluids, such as at the ends of process pipelines, equipment reserved interfaces, and system isolation sections.
- Key applications include oil platforms, chemical reaction equipment, high-pressure steam systems, and other hazardous conditions that require zero leakage.
- Used as a safety isolation component during pipeline pressure testing and system section maintenance.
advantages
- The final sealing insurance policy: hemispherical/butterfly type + fully welded joints, quite stressing capacity rendering the straight pipe extremely hard to produce leak.
- Impact-Resistant Design: The thickened curved configuration can bear water hammer impact and pressure fluctuations, safety factor more than 3 times higher than the standard.
- Corrosion Defense Matrix: Carbon Steel: Heavy duty anti-corrosive epoxy powder coating (≥250μm) or hot-dip galvanizing 20 years weather resistanceStainless Steel: Electrolytic polishing finish(Ra≤8 μm), conforms to ASME BPE.
- Installation Revolution: single-piece welded connection replaces flange-blind flange combinations, saving 80% installation time and eliminating bolt loosening risks.
- Large Range of Sizes: 1”- 24” full range, for use with ultra-deep-walled pipe (SCH160) and special alloy systems.
packing
- Compression-resistant nested packaging:
- ≤10″: High-strength corrugated box + EPS molded inner liner
- 10″: Steel-reinforced wooden box + internal honeycomb aluminum support frame
- Dual-layer protective sealing:
- Inner surface: Food-grade biodegradable rust-proof paper
- Outer surface: Heat-shrink film packaging + impact-resistant corner guards
- Smart error-proofing system:
- Printed welding bevel processing guidelines on the inner side of the packaging
- Fluorescent warning tape (with “No Impact” label) affixed to the outer box
- Minimalist traceability: Laser-engraved on the inner wall of the pipe cap, combining three codes (specification/pressure rating/material batch number).
