PIBIVIESSE high performance ball valves
PIBIVIESSE
Our partner PIBIVIESSE is an Italian high performance ball valve manufacturer, established in 1981. Their passion is to design and manufacture state-of-the-art ball valves “designed to perform – built to last” for the most demanding applications. Their commitment is to follow a “total quality” concept, from quotation to field service, without any compromise. The “Total Quality” concept made the company rapidly become a world-class, highly appreciated soft- and metal seated valve manufacturer. For many applications in Oil & Gas and other related industries, including Off-shore platforms and Sub-sea applications
Engineering & R&D
PIBIVIESSE have focused engineering and R&D teams, with strong expertise in design, FEA, Computational Fluid Dynamics (CFD), welding and manufacturing, work continuously on developing new solutions to fit customer needs.Using the most up-to-date technology, we can support our Customers in any special requirements which they may have or in developing and upgrading day by day the PIBIVIESSE products. When R&D requires extra competences, PIBIVIESSE works in cooperation with external research centers and universities, such as the Politecnico Milano, to carry out special projects on materials, calculations and on valve’s behavior in critical conditions.
Manufacturing
PIBIVIESSE components are produced in accordance with the highest quality standards. Operations are carried out by means of very-high precision machinery and skilled operators, to guarantee the design tolerances required by highly engineered valves to get the maximum precision and best quality needed. Make or buy decision is driven by capacity and type of products. To enhance and grow the overall products quality and reliability, we can count on long-term partnership with selected and qualified vendors. We like to think to our sub-suppliers as partners with a joint aim, nevertheless their performances are monitored and recorded on a regular basis.
Cladding & Welding
Four “state of the art” automatic units, able to cover most of the PIBIVIESSE production with the ultimate control technology, ensure high productivity and consistent quality of the output. Welding is another qualifying step of our manufacturing process. PIBIVIESSE capability covers different types of corrosion-resistant alloys and hard-facing materials, considering the application, the nature and temperature of the fluid/gas to be processed. For full penetration joints, PIBIVIESSE produces not only standard butt weld joints but also special assembly details such as “narrow-gap” profile to ensure welding of thick materials. All welding activities are qualified with or without PWHT (Post Weld Heat Treatment) based on project specification and always in compliance with the main international standard codes.
Assembly & Testing
PIBIVIESSE ball valves are 100% assembled in our shop floor and are subjected to extremely severe special tests far in excess of the requirements of the API and ANSI Standards. Our in-house testing capabilities, in addition to the standard requirements of International specification, include:
- High Pressure Nitrogen Test
- Low temperature (cryogenic) shell, seat and operational test (down to -196°)
- High temperature shell, seat and operational test (up to 400°C)
- Fugitive Emission Helium Leak Test at low, ambient and high temperature condition.
- Cycling operational “wear resistance” test
- Torque test
- Hyperbaric test to simulate sub-sea condition (down to 4000 mt water depth)
- Vacuum shell test
- Hysteresis and dead band verification for actuator/valve assembly (control valve)
Bending tests are to verify the performance of the valves when subject to bending loads transmitted by piping. These are performed both on side entry and top entry ball valves. Tests included checks of possible body distortion, torque and leakage rates.
