Product Overview
ASME Cold-Formed 290×2.5 304L Pipe End Cap for Molecular Sieve Cover is integrally manufactured from 304L stainless steel via cold-forming technology, with an inner diameter of 290mm and a thickness of 2.5mm. Specifically designed for molecular sieve equipment and supporting gas treatment systems, it integrates the core advantages of compact structure, reliable sealing, corrosion resistance and high cleanliness. It meets the strict requirements for sealing protection and medium cleanliness in molecular sieve storage and gas filtration scenarios, and is suitable for the end-sealing needs of various small and medium-sized molecular sieve equipment.
Performance Features
Compact and Stable Structure: One-piece cold-formed without spliced welds. Compared with traditional assembled end caps, it has a more stable structure and a weight optimisation of about 20%, facilitating installation without affecting the overall operational stability of molecular sieve equipment.
Excellent Dimensional Precision: Dimensional tolerance ≤±0.8mm and concentricity ≤±0.5mm, which can accurately match the installation precision requirements of molecular sieve tanks and supporting pipelines, reducing assembly gaps.
Strong Sealing Protection: No secondary welding process, structurally eliminating gas leakage and impurity intrusion, effectively ensuring the adsorption efficiency and service life of molecular sieves.
Corrosion Resistance & High Cleanliness: The natural oxide film on the surface of 304L stainless steel can resist corrosion from weak acids, weak alkalis and common gas media. The product has extremely low residue and is easy to clean, meeting the cleanliness standards of gas purification scenarios.
Manufacturing & Surface Treatment
Forming Process: Adopting 800-ton hydraulic press cold-forming technology, accurately adapting to the processing of 2.5mm thin-walled materials, ensuring the dimensional precision requirements of precision components for molecular sieve equipment.
Optional Surface Treatments: Chemical polishing (Ra≤1.6μm), passivation treatment, mirror polishing (Ra≤0.8μm), sandblasting (Ra 1.6μm-3.2μm), adapting to the contact needs of different gas media and service environments.
Quality Assurance
Full Inspection Process: 100% ultrasonic testing (UT) + liquid penetrant testing (PT), comprehensively inspecting product defects to ensure the sealing performance and safety of the molecular sieve system operation.
Authoritative Compliance: Compliant with standards such as ASME BPVC Sec.VIII Div 1, PED 2014/68/EU, and GB/T 25198-2023, with complete industry certifications, meeting the industry specification requirements for molecular sieve equipment.
Applications
Industrial Gas Purification: End sealing protection for molecular sieve adsorption towers and gas dryers.
Air Separation Equipment: Supporting protection and gas diversion for molecular sieve modules in air separation plants.
Chemical Gas Treatment: Molecular sieve protection in chemical feed gas purification and solvent recovery systems.
Food and Pharmaceutical Gases: Molecular sieve protection in the production of food-grade nitrogen and pharmaceutical-grade clean gases.
Environmental Protection: Sealing protection for molecular sieves in waste gas purification and tail gas treatment equipment.
Packaging & Services
Packaging Solutions: Waterproof wooden cases, pallet packaging (12-18 pieces/pallet), and vacuum packaging are available to avoid contamination during transportation and ensure product cleanliness.
Customisation Service: Personalised adjustment of outer diameter, length, thickness and opening size according to the specifications of molecular sieve equipment.
Sample Support: 3-5 samples provided for adaptability test evaluation of molecular sieve equipment.
Lead Time: 12 working days for standard orders, 22 working days for custom orders.
