Industry specific valve sealing solutions
Case Study Case Study Case Study
Oil and Gas
For valves operating in some of the mostinhospitable environments in the world, PPE'srange of elastomer grades are specifically tailoredto provide the ultimate sealing performance.
• High pressure and explosive decompression (ED) resistance.
• High temperature and HTHP capability (+325°C/627°F).
• Low temperature capability for API 6A & 6D valves (-46°C/-51°F).
• Chemical resistance to sour gas and oilfield media.
• NORSOK, NACE & TOTAL tested materials.
Chemical Processing
Sealing technology plays a crucial role in reducingfugitive emissions. PPE offers cost-effective solutionsfor the wide range of fluid transfer valve applicationsinvolved in the chemical processing industry.
• Outstanding mechanical properties.
• Excellent chemical resistance to a wide range of media.
• High temperature materials (+325°C/627°F).
• Low temperature grades for cryogenic valves.
• Steam resistance materials to withstand SIP cleaning.
Food and Pharmaceutical
Valve seals within food, dairy, water, pharmaceuticaland lifescience applications require excellentmechanical properties, chemical resistance andhygienic sealing capabilities.
• Excellent chemical resistance to a wide range of process media and CIP.
• Steam resistant materials to withstand SIP cleaning.
• Free from animal derived ingredients.
• FDA and 3-A compliant materials.
• USP class VI approved materials.
• WRAS and KTW drinking water approved materials.
Critical seals manufactured &delivered in 4 hours
ApplicationA blue-chip oil and gas service companyexperiencing seal failure and production stop on anoffshore platform.
Problem The customer had a twelve-hour window to source,pressure test and deliver to an offshore platform EDresistant O-rings for valves operating in highpressure, high temperature (HPHT) conditions.
PPE Solution PPE recommended EnDura® Z95X O-ringssupplied from stock in Aberdeen. In addition, newPTFE ball seats and PEEK wear seats weremanufactured using PPE’s rapid production service.
OutcomeThe time taken to solve the problem from initialcontact was just 4 hours, the critical seals weremanufactured, tested and delivered to the platformsaving the customer thousands of pounds inproduction downtime.
Urgent O-rings for valve MROproject on hold
ApplicationGlobal provider of valve sourcing, consultancy andMRO (maintenance, repair & overhaul) services tooffshore industry.
Problem Work stalled on shipment of valves being redresseddue to lack of high temperature O-ring seals.Incumbent competitor O-ring supplier quotingunacceptable lead-times.
PPE Solution Perlast®� G75TX high temperature resistantO-rings recommended and test data provideddemonstrating the materials excellent chemicalresistance, compression set and superior cold setproperties compared to competitor product.
OutcomePPE O-rings delivered within 5 working days ofquotation enabling swift commencement of projectwith minimal disruption.
Total containment API valve
ApplicationTotal containment valves for active pharmaceuticalingredient (API) transfer
Problem A lack of adequate sealing and difficulties withpressure were making total containment impossiblefor the Valve manufacturer
PPE Solution PPE worked closely with the client on the design ofthe seal to optimize the valves total containmentperformance. PPE’s Perlast® G74Sperfluoroelastomer seal material was chosen dueto its combined high levels of chemical resistanceand flexibility.
OutcomeActive Pharmaceutical Ingredient (API) powders cannow be transferred with less than 100 nano gramsof powder per m3 released into the atmospherefollowing a joint development between the valvemanufacturer and PPE.
Many industry approvals and conformities enable PPE to match a sealing material to every valve sealing application
