Shipment of ASME B16.20 Spiral Wound Gaskets and A105N Blind Flange for Malaysia Client

Haihao Group has completed inspection and arranged shipment of a matched set of sealing gaskets and large diameter blind flange for our Malaysia piping partner. This package combines ASME B16.20 spiral wound gaskets and one ASME B16.47 Series A blind flange, prepared for on-site isolation and flange sealing on a local industrial pipeline project.

ASME B16.20 spiral wound gasket 316L flexible graphite and A105N blind flange

Product Specification Summary

The ASME B16.20 spiral wound gasket forms the core sealing component in this batch. Each spiral wound gasket uses 316L stainless steel winding strip paired with flexible graphite filler, with a uniform 3 mm thickness and Class 150 pressure rating. We supplied four standard sizes: 2 inch, 6 inch, 12 inch and 28 inch. The flexible graphite filler delivers good resilience when flange bolts are tightened, while 316L winding provides reliable corrosion resistance suitable for humid tropical operating conditions common across Malaysia. Every spiral wound gasket was visually checked and marked following ASME B16.20 requirements before packing.

Alongside the gasket set, we supplied a 28 inch A105N blind flange built to ASME B16.47 Series A, raised face, Class 150. ASME B16.47 covers large flanges beyond the size range of ASME B16.5, so this A105N blind flange works perfectly with the matching 28 inch spiral wound gasket for line isolation. Forged A105N carbon steel offers stable mechanical performance at moderate temperatures, widely trusted by Southeast Asian EPC teams for temporary or permanent pipeline blank-off points. Matching gaskets and blind flanges from one supplier helps clients avoid dimension mismatch issues during installation.

At Haihao Group, we keep coordinated sourcing and inspection for flange and gasket packages. We can supply ASME B16.20 spiral wound gasket in different winding materials, filler types and pressure classes, together with ASME B16.47 large flanges, regular forged flanges and supporting fasteners. Full material test documents and third-party inspection options are available if required for Malaysia oil, gas and process piping projects. If you need matched flange and sealing components for your upcoming tender or site work, send over your drawing or specs for a formal quotation.
