Services

Maintenance on several kind of valves such as:

  • Trunnion and Floating Ball Valves side entry, top entry
  • Slab gate, Expanding gate Valves
  • Check Valves, single and double plates
  • Butterfly Valves
  • Pressure Safety Valves
  • Globe Valves
  • Plug Valves

Maintenance on various kinds of operators such as:

  • Manual gear boxes
  • Hydraulic actuators
  • Pneumatic actuators
  • Gas over oil actuators
  • Electrical actuators

Valves and Actuators refurbishment

we identify and analyze the root causes of valves or actuators failures and repair their components restoring the original functions.

Valve upgrading and modification

we measure and analyze the internal components of the existing valves and we re-build them following the new specifications and/or customer requirements. If the valve reveals damages or malfunctions on its components we are able to find the root cause of the damages. Study the best project solution in order to re-design the components with a new configuration targeted to the specific type of application that the valve has and supply them.

Reverse Engineering

we perform this kind of service in order to offer full valve spare parts even when the costumer does not possess the original drawings from the valve supplier. The procedure is the same used for the upgrading and modification activities (valve dismantle, inspection, measurement and production).

Workshop/Onshore/Offshore Tubing, fittings and hydraulic power unit

we are able to work with all kinds of fittings and manifolds (Autoclave, Swagelok type, BSP, NPT, GAS thread, etc.) .

We offer support and maintenance on the supply source during the tubing construction activities. We are able to work and repair the hydraulic pump mounted on the HPU having at disposal the suitable spare parts.

Special tools

we are able to design and produce special tools in order to disassemble and assemble the valves and the actuators located in restricted work areas and/or in vertical installation.

Teaching personnel to handle valves and actuators

we can train site personnel in order to give them the basic notions that skilled employees need when working in the valves and actuators market.

Commissioning activities on any kind of valves and actuators

we offer comprehensive technical support during start up and shutdown. Usually during these activities the client also requires skilled valves/actuators technicians in order to follow the commissioning procedures. Our experience is basically focused on these parts of the commissioning project and we can help the client supervising all the steps involved.

Supervising pigging activities

we offer technical support during the pigging activities in order to help site personnel in case of problems that could occur on valves or actuators. Usually during these activities the client also requires skilled valves/actuators technicians in order to follow the pigging activities. Our experience is focused in order to assist the client during all the steps involved.

Qualification tests as

  • PR2
  • Fire safe
  • Cryogenic
  • Fugitive emission
  • Bending under combined load and hydrostatic pressure of valves and flanges

All the above tests could be done Offshore, Onshore and in Workshop.

NDT tests: we are certified for

  • Magnetic level II (Portable Magnet and Contrast liquid)
  • Liquid penetrant level II (Cans of penetrant liquid and contrast liquid)
  • Acoustic (useful to reveal defects on casting material (i.e. body valves) and/or to detect leaks along pipelines
  • Application of strain gauges for Bending test.

All the above tests could be done Offshore, Onshore and in Workshop.

Document and record keeping

during and after job execution, all the activities are documented in a technical report in order to offer the client a complete and detailed description of the performed job; if requested we can offer a record of the tests performed following the specific procedures supplied by the client.

Seat flushing and lubricating operations

In case of valve internal leaks we are able to inject cleaners and lubricants into the valve seats injection port using special products in order to tentatively reduce the leakage when other maintenance operations on the valve are not possible due to the plant process period.

Emergency valve sealing

we are able to inject a special sealant material through injection port of the valve seats in order to definitively stop the leakage and maintain the pipeline in safety condition.This product is designed to provide a reliable, temporary seal even in severe leaking valves. This emergency sealing activity can be executed onshore and offshore.
