Cold-Formed 250×40×2.5 SUS304 Pipe End Cap For Molecular Sieve Cover

This type of molecular sieve cover has an inner diameter of 250mm, a height of 40mm, and a thickness of 2.5mm. It is integrally manufactured from SUS304 stainless steel through a cold-forming process. Specifically designed for molecular sieve equipment and supporting gas purification systems, it integrates the core advantages of compact structure, high cleanliness and corrosion resistance, meeting the strict requirements for sealing protection and medium cleanliness in molecular sieve storage and gas filtration scenarios.

• Compact and Stable: Compared with traditional welded covers, it has a more compact structure and 15%-30% optimised weight, facilitating installation without affecting the overall operational stability of molecular sieve equipment
• Precise Adaptability: Dimensional tolerance ±0.8mm, concentricity ≤±0.4mm, perfectly matching the installation precision requirements of molecular sieve tanks and supporting pipelines
• Sealing Protection: Integrally cold-formed without a secondary welding process, structurally eliminating gas leakage and impurity intrusion, ensuring molecular sieve adsorption efficiency
• Corrosion Resistance & High Cleanliness: The natural oxide film on the material surface can resist corrosion from weak acids, weak alkalis and gas media, with extremely low residue and easy cleaning, meeting the cleanliness standards of gas purification scenarios

• Forming Process: Cold forming with 600-ton hydraulic presses, suitable for processing 2.5mm thin materials and meeting 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

• Full Inspection Process: 100% ultrasonic testing + liquid penetrant testing to fully eliminate product defects and ensure the tightness and safety of the molecular sieve system
• Authoritative Certifications: Compliant with ASME BPVC Sec.VIII Div 1, PED 2014/68/EU, GB/T 25198-2010, etc., with relevant industry certifications, meeting the industry specifications for molecular sieve equipment
