Haihao Group Delivers ASME B16.20 Oval Gaskets to Russian Client

Haihao Group has finished production and shipment of ASME B16.20 oval gasket for a Russian high-pressure piping project. This batch of RTJ type oval gaskets is sized at 8 inch, ring groove number R49, rated for Class 900 service, manufactured from S30900 alloy material.

RTJ oval metal gaskets are designed for extreme high-pressure flange connections. The ASME B16.20 oval gasket features an elliptical cross-section, which creates reliable metal-to-metal sealing when compressed inside flange ring grooves. The S30900 material provides good resistance against oxidation and corrosion, fitting harsh operating conditions common in Russian oil and gas facilities.

Strict dimensional inspection and surface examination are completed before packing. Each ASME B16.20 oval gasket is checked for surface defects, dimensional tolerance and surface finish to match R49 ring groove geometry. As specified under ASME B16.20, the gasket maintains stable sealing performance under Class 900 pressure rating.

For high-pressure RTJ flange joints in Russia, many plant operators prefer alloy ring joint gaskets with full material traceability. Our team supplied material test certificates to verify S30900 composition and mechanical properties for this order. Every ASME B16.20 oval gasket is carefully packaged to prevent scratches or deformation during long-distance transit to Russia.

These alloy RTJ gaskets are widely used in high-pressure pipelines, pressure vessels and valve assemblies. Haihao Group can custom produce oval and octagonal ring joint gaskets in various alloys and sizes, complying with ASME B16.20 for energy and petrochemical projects across CIS regions.
