Import Adaptor — Buy in Bulk from Supplier in China

The flanged adapter and coupling from Hydera Machinery Limited is a ductile iron pipe fitting designed for fluid transfer systems with PN10 and PN16 pressure ratings up to DN300. Manufactured from industrial-grade materials with corrosion-resistant properties, this adaptor connects flanged pipe sections to plain-ended pipes or between two flanged sections. The dismantling joint feature permits removal and replacement of adjacent piping without cutting, which reduces downtime during maintenance. Its robust construction suits water, sewage and industrial fluid applications where mechanical joint integrity is critical.

Ductile iron body with epoxy coating is standard for this product category, though specific material grades should be confirmed with the supplier. The flanged ends comply with EN 1092-1 or ANSI/AWWA C110/C153 dimensions depending on the intended market, with bolt circle and drilling patterns matched to the pressure class. Gaskets are typically EPDM or NBR rubber, selected for compatibility with the conveyed medium and operating temperature. Surface finish and lining options (cement mortar, bituminous coating, fusion-bonded epoxy) vary by application; buyers should specify drinking water or aggressive service requirements.

Water treatment contractors, municipal engineering departments and chemical processing plants are the primary buyers of PN10 and PN16 flanged adaptors. The DN300 maximum size handles main distribution lines and plant interconnects. Installation requires torque-controlled bolting to prevent gasket over-compression. Buyers should confirm with Hydera Machinery Limited whether factory pressure testing, material certificates and coating specifications are available, as these are not stated in the listing.

Hydera Machinery Limited is located at No.6 Jintan Branch Road, Qingdao 266071, Shandong, China. The supplier carries an 'imported' tier designation and a 'harbor' trust tier. The response rate is recorded at 0.00 percent with zero average response hours, which indicates no response data is available through the platform. Buyers should treat communication speed as unverified and should test responsiveness directly before relying on time-sensitive procurement.

The listing describes flanged adaptors and couplings for fluid transfer systems, with specific mention of PN10 and PN16 pressure classes and dismantling joint functionality. No factory size, year of establishment, revenue, headcount, client references or specific certifications are provided in the source data. The supplier address places it in Qingdao, a significant port city with established foundry and valve manufacturing clusters, but this geographic context does not confirm production capability for this specific supplier.
