Integral Flange Crossover Adapters: API RTJ x Weco Fig 1502 / Fig 602 (5,000 to 15,000 PSI)
In high-pressure well testing, hydraulic fracturing, and acidizing manifolds, transition points between flanged Christmas trees and temporary hammer union flowlines represent high-risk mechanical boundaries. Shanghai PME Industrial supplies high-performance integral flange crossover spools engineered to maintain leak-proof fluid containment under pressure ratings up to 15,000 PSI CWP. Built strictly from mono-block forged alloy steel, these transition fittings eliminate welded heat-affected zones, providing extreme fatigue resistance in severe oilfield environments.
We are pleased to announce the successful final inspection and packing completion of a specialized batch of nace h2s flange adapter crossovers custom-manufactured for a leading South American oilfield service contractor. Having passed rigorous Charpy V-notch impact testing, hardness verification, and hydrostatic shell testing, this consignment is fully packed in seaworthy plywood crates and dispatched for ocean freight export to South America.
Flange x Weco Union Crossover Adapters
Precision-machined mono-block crossovers connecting API 6A RTJ flanges directly to Weco Fig 1502 & Fig 602 male/female ends.
API 6A Ring Joint (RTJ) Flange Face Detail
Close-up view of precision-milled BX-154 and R-24 ring grooves, ensuring gas-tight sealing in sour gas (H2S) service environments.
Seaworthy Plywood Crate (South America)
Completed order securely bolted and rust-inhibited inside heavy-duty wooden crates, prepared for ocean container transit.
Engineering Advantage: Why Specify PME Integral Crossovers?
When assembling high-pressure fluid manifolds, utilizing a single-piece 15000 psi crossover flange forged from 4130/4140 alloy steel allows PME to eliminate potential leak paths and internal flow erosion, fully compliant with NACE MR0175 sour gas specifications for South American shale and offshore operations.

Quality Verification & Ocean Logistics Standards
Every fig 1502 weco flange and fig 602 flange crossover leaving our facility undergoes standard API 6A hydrostatic and non-destructive testing:
- Hydrostatic Shell Test: Held at 1.5 times working pressure (up to 22,500 PSI) for extended hold periods with zero pressure drop.
- Material Traceability: 100% mill test reports (MTR) provided.
- Surface Treatment & Rust Prevention: Internal bore and sealing grooves are coated with heavy-duty corrosion inhibitors and fitted with heavy plastic end protectors.
- Seaworthy Ocean Freight Packaging: Products are strapped on wood frames plywood crates designed for South American maritime transit.
