Jacketed Vessels & Specialty Exchangers NDT
Authoritative reference for Dimpled Jackets, Half-Pipe Coils, Printed Circuit Exchangers (PCHE), Scraped Surface Exchangers (SSHE), and Teflon immersion coils. Inspect CUI on shell jackets and skirts.
Screen reactor jackets and insulated support skirts for CUI wall loss right through weather cladding without insulation stripping.
Specialty Heat Exchanger Architectures & NDT Methods
Jacketed Vessels & Reactor Jackets
Outer heat transfer jackets welded directly to chemical reactor walls and storage vessels to heat or cool process fluids. Prone to severe Corrosion Under Insulation (CUI) under weather cladding.
Printed Circuit Heat Exchangers (PCHE)
Ultra-compact heat exchangers constructed from chemically etched plates solid-state diffusion bonded under high temperature and pressure for supercritical CO2 and LNG service.
Scraped Surface Heat Exchangers (SSHE)
Features internal rotating scraper blades that continuously wipe viscous, sticky, or crystallizing fluids off the inner transfer wall in food, pharmaceutical, and wax processing.
Fluoropolymer / Teflon Immersion Coils
PFA/PTFE fluoropolymer tubing bundles inserted into pickling tanks and semiconductor chemical baths where all metal alloys would rapidly dissolve.
How B2B Project Workflow Works
From initial RFP scope to direct client sign-off. NDT EXCHANGE does not charge commissions or manage project payments.
RFP Scope
Asset Owner posts turnkey B2B inspection scope with technical specifications, asset list, and required NDT methods.
Competitive Bids
Certified NDT agencies submit competitive proposals (Fixed-Bid / T&M) detailing technician rosters and day rates.
Direct Settlement / Escrow
Client awards bid and sets up direct milestone payment or escrow — NDT EXCHANGE never holds or manages project funds.
Field Execution
Level II/III inspectors perform on-site testing (PAUT, TOFD, MFL, UT), capturing flaw data and calibration overlays.
Sign-Off & Payout
Level III auditor reviews findings; upon client sign-off, funds release directly to agency with 0% platform commission.
