Tri Tool provides critical solutions for international land-based pipeline

TRI Tool Services SM provides international mission critical support such as the equipment implementation for a major petroleum producer in Oman. This two-year project required multi-level support including custom equipment engineering, equipment logistics, and specialised customer training, along with field machining and project coordination personnel. The customer was confronted with a petroleum transportation problem that would require advanced technical support. Corrosive Hydrogen Sulfide components in raw petroleum, in association with the factors of heat and friction, chemically and

mechanically attack and dissolve the inner bore surface of pipelines. This damage can amount to over an inch of dimensional loss per year, and in some instances can be theoretically greater than the original wall thickness. One approach to deal with the problem is to fully line the ID bore of carbon steel pipe with a uniform cladding of Inconel 625 for its proven characteristics of acid resistance and weldability. This requires weld end preparation to ensure that when welding the joint with Inconel filler wire, the root pass provides an uninterrupted corrosion resistant surface. The Inconel welds demanded extreme accuracy and the

pipeline sections to be used were known to have a serious out-of-round condition. The equipment that was selected for this project was Tri Tool’s PFM 816 Pipemaster ® , the versatile Model 224B Bevelmaster ® , and the newly designed Tri Tool ® Laser Dimensioning System. Pipeline section ends were precisely ID bored to uniform wall thickness with a PFM 816 fitted with an OD tracking system. Pipe ends were measured, indexed and cataloged for bore matching with Tri Tool’s new Laser Dimensioning System. Weld end preparation was performed immediately prior to welding with the Model 224B. Tri Tool also provided assistance with implementing a mobile welding station that could reliably position the production equipment for optimal prep and weld cycle times. Tri Tool can support all API 5L piping operations, combining multidisciplinary machine and service technologies for the most demanding applications, anywhere in the world.

Dependency on heating guns to apply toxic product must be avoided. Working offshore means operating under harsh conditions. This needs a very applicator-friendly approach.” Both companies understand this very well. Therefore, this alliance offers clients a system which can be easily applied to any difficult to coat object. The system is very cost-effective, simple and easy. BASF Polyurethanes UK Limited

BASF and Stopaq join forces in prevention and thermal insulation package for offshore industry

BASF is well known for the Nordstream Offshore Pipeline Project from Russia to Germany. Stopaq has built its reputation around anti-corrosion protection of fieldjoints, risers, spools, land/sea pipes and j-tubes, especially in the Middle East (Safaniyah, Manifa and Karan projects). Both companies have an excellent longstanding reputation, history and track record in the offshore industry. To better cater to the needs of the offshore clients, the two companies are forming a marketing alliance to offer a one-stop shop for the entire corrosion prevention and thermal insulation package. This will offer

the clients a great source for the protection of the valuable infrastructural assets. The market demands safe, easy and green solutions, that last for as long as possible. That’s what the future of the supplied material holds in store. Mr Lynam, business development manager oil and gas of BASF Polyurethanes, said: “We see preventing corrosion and system integrity as our common mission.” Via this new common system, Stopaq and BASF Polyurethanes can offer more control in all process steps from preparation, application and service to go beyond the design life.
