Response SLA & FAQ

Standard SLA for chemical processing equipment support is 8 hours for email and 2 hours for urgent subsea hydraulic connector issues. Visit our FAQ page for common questions on expansion joint installation and pressure ratings.

What pressure range do the flange adapters cover?	Series 4000 adapters are hydrostatically tested at 1.5× rated pressure and handle up to 6000 psi. They match ANSI Class 300 and 600 flanges for refinery and subsea service.
Which materials resist corrosive media in chemical lines?	Standard bodies are carbon steel with a corrosion-resistant epoxy coating. For highly aggressive fluids, duplex stainless steel or PTFE-lined options are available on request.
How deep can the subsea hydraulic connector operate?	The SHC-9 is rated for depths exceeding 3000 meters. Its dual-seal metal architecture prevents seawater ingress while maintaining internal pressures up to 10,000 psi.
What movements does the expansion joint absorb?	Model EJ-200 absorbs axial, lateral, and angular movements in piping systems handling acids, caustics, and high-temperature fluids up to 250°F. Service life exceeds 50,000 cycles.
Are these components compatible with existing ANSI flanges?	Yes. Series 4000 adapters and EJ-200 joints are available in flanged and weld-end configurations that match ANSI Class 300 and 600 bolt patterns without field modification.
What testing is performed before shipment?	Every unit undergoes hydrostatic testing at 1.5× rated pressure. Subsea connectors also receive a helium leak test and functional stab-cycle verification.
