从China供应商批发进口Alfa Laval Plate Heat Exchanger Gaskets A20 — FOB条款

The Alfa Laval A20 plate heat exchanger gasket serves as a replacement seal for the A20 model, a larger-capacity unit than the A15B series and commonly specified in process industries requiring greater thermal duty. This gasket seals the perimeter and port areas between corrugated stainless steel plates, maintaining separation of process and utility fluids while accommodating differential thermal expansion. M.C. Heat Exchanger produces this component at its Wuxi facility, drawing on tooling that covers the A-series model line from A10 through A35. The A20 plate pack typically accommodates higher flow rates and larger port diameters than smaller A-series models, with gasket design reflecting these increased mechanical and hydraulic loads.

Elastomer selection for the A20 follows the same material science principles as smaller plate heat exchangers, with compound choice dictated by chemical resistance, temperature exposure, and regulatory requirements. NBR compounds suit closed-loop water and lubricating oil circuits, EPDM handles boiler feed water and steam condensate, and specialised HNBR or Viton grades address sour gas condensers and chemical processing duties. The A20 gasket profile incorporates port rings integral to the field gasket or supplied as separate rings, depending on the vintage of the original plate pack. Typical gasket thickness for this frame size ranges from 3.0 mm to 4.0 mm uncompressed, with plate pack tightening procedures specified by torque sequence rather than bolt load to achieve uniform compression across the larger seal area.

Primary buyers include petrochemical refineries, power generation plants, food and beverage processors, and large building services contractors. The A20's larger plate surface area makes it economical for applications where the A15B would require multiple units in parallel. When sourcing from M.C. Heat Exchanger, technical buyers should focus verification efforts on port diameter, overall gasket envelope dimensions, and whether the supplier's A20 variant matches early or late production A20 plate geometries, as Alfa Laval introduced subtle design revisions over this model's production life. The absence of response rate data suggests proactive follow-up by telephone or alternative contact channels may be necessary to secure quotations.

M.C. Heat Exchanger is headquartered at No.28 Xigang Road, Wuxi City, Jiangsu Province, China, operating within the Yangtze River Delta manufacturing belt with access to Shanghai Port for export shipments. The supplier's profile indicates a harbour trust classification, representing entry-level platform verification without extended due diligence documentation. Response metrics show zero recorded response rate and zero average response hours, which may reflect inactive measurement rather than operational incapacity, but buyers should treat communication reliability as unverified. No information is disclosed about factory ownership structure, years in operation, or quality management system certifications such as ISO 9001 or ISO 14001.

The supplier's advertised capability spans replacement gaskets and plates for over a dozen international heat exchanger brands, with particular emphasis on European OEM aftermarket coverage. The model list includes extensive Alfa Laval series coverage, GEA, APV/SPX, and numerous lesser-known brands, implying significant pattern inventory and tooling investment. For the A20 specifically, the supplier groups this within a broader A-series capability that includes A10, A15, A35, and B-width variants. No financial data, employee counts, client references, or case studies are provided. Buyers should conduct independent verification of manufacturing premises, request references from existing export customers, and validate that claimed production capacity aligns with order volume requirements before establishing preferred supplier status.
