CARPENTERIA MECCANICA LUIGI ROTA

since 1983

Monolithic Insulating Joints

LR

FOR ONSHORE AND OFFSHORE PROJECTS Carpenteria Meccanica Luigi Rota operates for more than 25 years in the field of structural metalwork construction and industrial assemblies and has been specializing in the production of monolithic insulating joints for pipelines.

AREAS AND PLANTS

EMPLOYEES

Covered area: Open area:

15 people

Offices 200 m2 Warehouse: 2000 m2 2000 m2

All our staff is highly qualified and specialized.

MAIN EQUIPMENT n.2 bridge cranes of 20 T n.1 fork lift semi-automatic belt units for cold-cutting of pipes tool-machines for horizontal and vertical turning bevelling machines - electrical - hand-operated and semi-automatic welding units: GTAW, GMAW, SMAW and SAW equipment hydraulic vertical presses - air compressors

Carpenteria Meccanica Luigi Rota produces and distributes high quality monolithic insulating joints for the oil&gas industry. Wherever you find pipeline and gas distribution systems you will also find a wide array of our products. When our monolithic insulating joints are used in the right application, savings in the overall costs of the entire corrosion control system are granted.

FOR ONSHORE PROJECTS Limiting the spread and hence the cost of cathodic protection to those pipes that need to be effectively and economically protected by the main cathodic protection system. Electrically dividing long pipelines into distinctive cathodic protection system. Isolating a pipeline and ensuring that cathodic protection or stray electricity currents do not cause increased corrosion. Providing protection against earthing currents at domestic and industrial premises where the PME system is in use.

FOR OFFSHORE PROJECTS Isolating the pipeline cathodic protection system in riser pipes and offshore structures. At field “tie-ins”.

DEMANGING APPLICATIONS

CERTIFICATES UNI EN ISO 9001:2008 EA17 sector, Reg. number: 0312294 PED Modulo H1

Making dependable isolation joints with dependable seals for safety-critical and extreme applications goes beyond excellence in design and manufacturing. It also means a strong commitment to quality. Carpenteria Meccanica Luigi Rota as a major isolation joints manufacturer, has access to substantial application data and a wealth of experience. Our practical know-how in using very complex and secure methods is supported by finite element analysis to combine experience and technology at the same time. The most extreme environments demand a strong commitment in finding the best sealing solution. Carpenteria Meccanica Luigi Rota is committed in achieving its objectives in very demanding services for high pressure or hard vacuum applications as well as against corrosive chemical and very low temperature in-line services.

WELDING AND NON DESTRUCTIVE TESTING • The metal components that make up the so-called “standard” joints are joined together by means of “fillet welds” if requested, the “fillet weld” seam may be checked by non destructive tests using dye penetrants and magnetoscopic inspections. • With different preparation “butt welds” can be used. In this case, inspections by x-rays and ultrasounds can be carried out. • All welding processes are in accordance with ASME VIII and IX and are certified by independent and International Authorities.
