Entagral Engineering team has managed many custom projects, domestic and international, including design and analysis and/or turnkey support for land based, offshore and subsea customer assets. Included below is a cross-section of memorable projects.

• 3/4 inch nom mechanical xline fitting. The X-line provides intervention of the pipeline by completely severing pipeline whilst sealing and restraining pressure end load and adding structural reinforcement to pipe.
• 18 inch pipeline jacket repair. Designed and analyzed outer weld-on reinforcement jacket to requirements of ASME B31.3 pipeline code.
• 36 inch mitered refractory jacket repair. Refractory lined mitered pipeline elbow developed hotspots due to loss of refractory. Engineered mitered replacement jacket.
• 36 inch nom elbow hottap. A customer fixture and hottap nozzle were designed to allow tapping into a 36 inch nom long radius elbow.
• As-built valve bridge. A legacy 12 inch ammonia valve with inability to procure discontinued parts and damaged bridge was dismantled and back engineered with Faro® arm data.
• Custom subsea valve repair installation. A vent valve leaking natural gas on a subsea valve bonnet was suppressed to zero leakage.
• Downstream mechanical hottap. Upstream technology was utilized and mechanical hottap was engineered, installed and tapped in a refinery with volatile service environment – steady state temperature application.
• Entagral test bay turnkey project. Designed, analyzed, and constructed by Entagral for high pressure oil field equipment testing. Scope of service was to provide secondary projectile mitigation and enhanced safety.
• Long term storage canisters. Designed and analyzed for long term, climatized storage of contingency subsea pipeline equipment.
• Nuclear power plant tube bundle repair. Subsea pipeline technology utilized for geometrically optimized leak suppression in a nuclear power plant with radiation resistant seals.
• Pipe crimp Assembly. Hydraulically actuated crimp blocks for pipeline isolation and sealing.
• Pipe trunnion repair with grip support. Corroded pipeline trunnion online replacement leak repair fitting and long term gripping to provide weight support for hydrocarbon pipeline.
• Pipeline double grip housing. Temporary pipeline restraint and reinforcement for pipeline separation concerns.
• Remote handling and installation tool for nuclear power plant tube bundle repair. The tool was designed to manipulate and install repair clamp through a highly obstructed environment.
• Roof tank repair. Roof tank and nozzle sealing plus reinforcement with compound rooftop angle. The metrology of the roof was determined and sealing surface precisely machined via CNC.
• Structural multiplane pipeline repair. Flanged design with multiple phase metrology to seal and reinforce pipeline and pipeline fittings.
• Tank testing subsea fitting. Customer required tank testing to qualify custom subsea leak suppression fitting. Testing included surface refurbishment and sealing to 3350 psi.
• Transducer flange repair in nuclear plant. Finite element analysis and supplemental repair fittings necessary to suppress leak in nuclear facility.
• Repair of a corroded valve on a 10 foot highly obstructed refinery pressure vessel.
• Back engineering and finite element analysis of an industrial tank cleaning water cannon.
