Import Cdm Elliptical Head And Spherical Head — Buy in Bulk from Supplier in China

The CDM Elliptical Head and Spherical Head are precision-engineered titanium components manufactured by CDM Titanium - Shanghai CDM Industry Co., Ltd. These parts are produced from Grade 2 titanium as per ASTM B265, with elliptical heads conforming to ASME BPVC Section VIII Division 1 geometry and spherical heads meeting ASME B16.5 pressure vessel standards. Dimensions are available in diameters from 50mm to 600mm, with wall thicknesses ranging from 1.5mm to 12mm, based on customer drawings or standard industry profiles.

Titanium Grade 2 is selected for its balance of corrosion resistance, weldability, and mechanical strength under moderate stress. The heads are formed using hot isostatic pressing and CNC machining to maintain dimensional accuracy within ±0.1mm. Surface finish typically meets Ra 0.8μm, though custom finishes up to Ra 0.2μm are available. These are not plated or coated parts; the base material provides all performance characteristics. The material is verified to be free from titanium hydride embrittlement through routine metallographic inspection.

These components are primarily used in chemical processing vessels, marine heat exchangers, and aerospace fluid systems where saltwater exposure or high-pressure cyclic loads are present. Buyers include OEMs in offshore energy, pharmaceutical equipment manufacturing, and defense subcontractors. Trade terms are typically FOB Shanghai Port, with minimum order quantities starting at one unit for prototype orders and 10 units for production runs. Packaging is in custom wooden crates with desiccant and foam inserts to prevent surface abrasion during transit.

CDM Titanium - Shanghai CDM Industry Co., Ltd. is a specialized manufacturer of titanium pressure components based in Shanghai's Pudong High Technology Zone. The company focuses exclusively on titanium heads, nozzles, and vessel fittings, with no product lines in stainless steel or other alloys. The supplier is verified as an importer with harbor-level trust status, indicating customs compliance and export history, but no ISO certification or third-party audit reports are disclosed in the listing.

There is no public information on company size, years in operation, or client list. The supplier does not claim to be a factory or distributor, and no production capacity figures are provided. Response metrics show zero response rate and zero average response time, suggesting limited buyer communication infrastructure. Buyers should treat this as a direct sourcing channel with no established service history and must verify all claims independently before placing orders.
