S30408 Pipe End Cap With 159mm Diameter And 6mm Thickness For Pressure Vessels

一,Basic Information

Model & Specification: EHB159*6, inner diameter 159mm, thickness 6mm, suitable for medium-caliber pipes commonly used in industrial pipeline systems.

Material Options: Mainly aluminum alloys 6061 and 5052. Alloy 6061 has high strength and good weldability, suitable for pipeline scenarios requiring structural support; Alloy 5052 has excellent corrosion resistance, suitable for humid or corrosive environments such as chemical industry and marine fields. Customizable materials include carbon steel (Q235B, Q345R), stainless steel (SUS304, SUS316L) and duplex steel (S31803). All aluminum materials are sourced from certified suppliers such as Chinalco and Alcoa, with complete Material Test Certificates (MTC) to ensure quality traceability.

二,Core Performance & Design

Lightweight & Structural Stability: Compared with stainless steel or carbon steel pipe end caps of the same specification, the weight is reduced by 30%-50%, which reduces the overall load of the pipeline, facilitating transportation and installation. At the same time, the 6mm thickness design remains stable under the working pressure of 0.1MPa-12MPa, suitable for non-high-pressure pipelines, such as conveying pipelines and tank connecting pipes.

Precise Dimension Control: Inner diameter tolerance ≤ ±1mm, using precision cutting technology; if an opening needs to be reserved, the opening size can be customized (50mm-180mm), and the advanced CNC machining ensures the opening concentricity tolerance ≤ ±0.5mm, ensuring seamless assembly with pipelines, valves or detection interfaces.

Leak-Proof & Integrated Design: The integrated forming structure eliminates the need for secondary welding of pipeline interfaces, reducing the risk of leakage, simplifying the assembly process, and avoiding the impact of welding stress on the structural integrity of the pipe end cap.

Corrosion Resistance: The natural oxide film on the aluminum surface can resist atmospheric corrosion, weak acids and alkalis, suitable for pipeline scenarios with aqueous solutions, food-grade media and chemical reagents, without causing medium contamination.

三,Forming & Surface Treatment

Forming Process: Cold forming process is adopted, with more than 8 800-ton hydraulic presses to precisely control the pressure, avoiding thermal deformation and ensuring the mechanical properties of 6mm thin aluminum plates. The formed surface is smooth without cracks or wrinkles. For customized products with thick walls or high-strength alloys, the hot forming process is used, with the heating temperature controlled at 350℃-500℃ (adjusted according to the alloy type), and stress relief annealing is carried out after forming to improve dimensional stability.

Surface Treatment: Chemical polishing (surface roughness Ra ≤ 1.6μm, easy to clean, suitable for food and pharmaceutical pipelines), anodizing (forming a wear-resistant oxide layer, customizable colors such as silver and black, enhancing corrosion resistance and aesthetics), passivation treatment (strengthening the surface oxide film, suitable for chemical pipelines) and anti-rust coating (food-grade anti-rust oil/film, used for anti-oxidation during storage and transportation) are provided. Mirror polishing (Ra ≤ 0.8μm) or sandblasting (Ra 1.6μm-3.2μm) can be customized on demand.

四,Inspection Standards

Comprehensive Quality Inspection: 100% ultrasonic testing (UT) to check internal inclusions, voids and other defects; liquid penetrant testing (PT) to detect surface and near-surface cracks and pinholes to prevent leakage; high-precision calipers and coordinate measuring machines (CMM) to test key dimensions to meet design requirements; sampling pressure tests of 1.5 times the rated working pressure to verify pressure-bearing and sealing performance; visual inspection of surface scratches and dents to ensure intact appearance.

Certification Standards: Compliant with ASME BPVC Sec.VIII Div.1 (North American and global markets), PED 2014/68/EU (EU CE certification), GB/T 25198-2010 (Chinese national standard), and can be customized to meet JIS B8243 (Japanese market); with ISO 9001:2015 quality management system certification, ASME "U" Stamp and PED Module H certification.

五,Practical Application Scenarios

Food & Beverage Industry: Used for sealing the end of juice, dairy products and edible oil conveying pipelines, with corrosion resistance, non-toxicity and easy cleaning, meeting food hygiene standards.

Chemical Industry: Suitable for solvent conveying pipelines and low-pressure chemical reactor connecting pipes, resisting corrosion of chemical reagents and ensuring pipeline sealing safety.

New Energy Field: Used for battery electrolyte conveying pipelines and hydrogen energy equipment auxiliary pipelines, the lightweight design meets the overall weight reduction needs of equipment, and the corrosion resistance is suitable for the electrolyte environment.

Water Treatment Industry: Sealing the end of pressure filters and water storage pipelines, resisting water corrosion and ensuring water quality is not polluted.

Pharmaceutical Industry: Sealing the conveying pipelines of medicinal liquids and intermediates, meeting hygiene requirements, and the surface treatment process avoids medium residue.
