CuNi 70/30 Copper Nickel Cap, also known as cupronickel pipe end cap, is a precision forged pipe fitting manufactured strictly according to ASME B16.5 Class150 standards and UNS C71500 material specifications. Made of 70% copper and 30% nickel alloy, this pipe cap adopts integral hot forging forming technology without welding joints. Compared with ordinary cast pipe caps, it features dense internal structure, uniform material composition and no microscopic pores or cracks. After fine finishing and stress relief treatment, the product boasts stable chemical properties and excellent overall rigidity. It is a professional sealing fitting specially used for blocking and terminating industrial pipeline ends, widely recognized for high-standard marine and corrosive pipeline systems.

3. Application Scope & Product Function
This copper nickel end cap serves as a key pipeline sealing component, mainly used to block pipeline terminals, seal redundant pipe openings and isolate internal fluid to prevent medium leakage and external impurity entry. It is widely applied in offshore oil platforms, marine ship pipeline systems, seawater desalination projects, chemical corrosive medium pipelines and power plant cooling piping systems. Adapted to harsh saltwater and acid-base environments, it can long-term stabilize pipeline sealing performance, effectively protect pipeline ends from corrosion, collision and damage, and ensure the safety and tightness of the entire piping system.
4. Product Core Advantages
Strong Corrosion Resistance: Professional 70/30 copper-nickel alloy material effectively resists seawater erosion, salt fog and chemical medium corrosion, far exceeding the service life of carbon steel and stainless steel caps.
High Pressure Resistance: Integral forged structure features high density and strong compression resistance, which can stably bear high-pressure fluid impact without deformation or rupture.
Zero Leakage Sealing Performance: Precise dimensional tolerance and smooth docking surface ensure perfect fit with copper nickel pipes and flanges, achieving fully airtight and watertight sealing effect.
Durable & Low Maintenance: Excellent oxidation resistance and structural stability reduce later maintenance frequency and replacement cost for industrial pipelines.
5. Packaging, Delivery & After-sales Service
We adopt standard export packaging with waterproof film, shockproof cushioning and solid wooden box packaging to avoid scratches, oxidation and extrusion damage during long-distance transportation. We support flexible payment methods and global efficient delivery, with sufficient stock for conventional specifications and personalized customization for special sizes.
