Topsides & Hulls

Offshore Topsides & Hull Piping

 Taper-Lok and CofferLok Compact Engineered Connectors can be used on all  topsides and hulls process systems, manifolds, connectors on valves,  equipment, boarding valves, skid packages, risers, chemical injection  systems and membrane separation systems.  When used platform wide in  ANSI class 600# and above, typical weight savings of up to one million  lbs. can be realized. 

Weight and Space Savings

 Our Engineered Connectors save weight and space. With weight savings of  up to 80% in comparison to ANSI flanges, our engineered connection  systems can typically save up to one million pounds on the topsides of  an offshore floating platform. These connectors also offer space savings  of up to 82% with smaller outside diameter and length dimensions  compared to ANSI/API flanges. Pipe runs can be designed closer together  to create more room for process equipment and future tie-backs. Our  connectors are ideal for small O.D. pull-in-head requirements. 

Taper-Lok Wide-Area Seal Technology

 Taper-Lok Connectors metal-to-metal seal ring technology offers  leak-free reliability over traditional ANSI and API gaskets. Our seal  rings offer the equivalency of welded joint integrity and can be used in  critical and chronic leak areas. Many “metal to metal” ring type  connections rely on a narrow band of contact.  In principle, this will  be enough, but in practice, in field conditions they are easily damaged.  Taper-Lok incorporates a Wide Area Seal that is up to 20 times the  contact area of other metal to metal seals.  Ensuring a robust and  forgiving connection that can easily withstand the rigors of repeated  job site connections in tough conditions. 

CofferLok Clamp Advantages over ANSI B16.5 Flanges

 Self energized and pressure energized seal.  Seal ring is designed to be  reusable.  Small relative movements between hubs can be accommodated by  seal ring deflection.  Clamp assembly lighter and requires less space.   Clamp bolts are oriented perpendicular to pressure end thrust and are  not subjected to hydrostatic loading due to pressure.  Small outside  dimensions allow use in more congested areas.  Clamps can be  conveniently rotated for desired bolt orientation.  Four bolt design has  built in safety factor which allows for bolt failure without loss of  sealing integrity.  The connectors method of sealing does not require  precision bolt loading, thus easier to make up.  Reliable 1 X10-6 cc/sec  leak detection (one part per million) 

Topside and Hull Piping Spools

 Taper-Lok Connectors with a male/female self-aligning flange  configuration install up to 75% faster and easier than ANSI or API  flanges.  CNOOC PL 19-3 Phase II project was installed 20 days early and  saved the client $3 million due to the ease of installation.  Taper-Lok  swivel and weld neck flanges can come with a spherical nose  configuration on the male flange which allows for 2-3 degrees of  misalignment. 

CofferLok Compact Flange (NORSOK L-005)

 Offers outstanding benefits whenever size, weight and stress are  critical factors in pipe-design.  Compared to ANSI Flange connections,  CofferLok Compact Flanges (NORSOK L-005) save up to 82% of weight  withstanding high bending and tension loads without leaking—No  retightening of bolts required—Two independent metal sealing surfaces, a  third environmental seal area, and static connection strength—Design  codes ASME VIII Div.2 Appendix 4 and 6, ANSI/ASME B31.3, B31.8, BS 500  and API—The NORSOKL-005 standard covers up to 2500# class. 5K, 10K and  15K psi pressures available—CofferLok “E” seal ring is interchangeable  with NORSOK IX seal ring—NORSOK L-005 is also known as ISO 27509. 

Works on Valves, Vessels and Other Equipment

 Our Engineered Connectors are used to save weight and space in offshore  applications and used for leak-free service in critical petrochemical  and refinery applications.  We work will all valve, vessel and other  OEMS to use our Taper-Lok and CofferLok on their equipment.  These  connectors fully replace ANSI and API designed flanges.  Third party  manufacturers can either weld on our engineered connectors to the end of  their equipment or we will license them to machine the connector  integral to their product. 

Damage in Seal Area -Not Usually A Problem

 Taper-Lok Connectors are the most robust flange connectors in the world .  In the pictures shown, damage occurred to the Taper-Lok male nose and  the joint still passed hydro-test due to its wide contact area seal  design. Taper-Lok’s metal-to-metal seal has 20 x contact area vs. other  seals. This means scratches and damage can occur and the joint will  still be leak free.  This is one reason why Taper-Lok connectors have  never had a leak in over 55 years of service.
