Our valve repair services offer solutions for the diagnosis and repair of valves all types and sizes. What we offer is a combination of skilled technicians and modern instrument calibration/valve workshop environment allowing us to routinely perform operations that supersedes our competitors. Should your requirements be to provide on-site, routine or emergency repair services, you can count on our expertise to deliver services that assures you of the integrity of your instruments and consistent process control.
Why Use Us?
PENCHN has made deliberate steps to acquire a containerized mobile digital calibration test rig for the calibration and recertification of pressure safety valves It is mounted within an offshore container designed and tested in accordance with DNV 2.7-1. In addition, this container is equipped with ATEX approved lighting and electrical wiring, and fitted out with a heavy duty workbench, lifting beam and chain block.
Inspections, Testing & Certification
PENCHIN through its certified personnel, provides installation and commissioning of valve equipment for plant performance. As a leading oil & gas service provider, we understand that safety is a delicate process. We recognize that the proper handling and installation of equipment is central to all operations to ensure that our customer’s equipment will always function as designed.
Maintenance
PENCHIN provides valve maintenance and repair services, that helps clean the inner mechanisms and replace anything that is worn. Over time, mineralization, rust and corrosion that affect the valve stem, springs, coils, nuts and other metal parts. In addition, we also attend to valve plastic or rubber parts that may need repair or replacement, which may include:
- Glands
- Bushings
- Gaskets
- Packing
- O-rings
Parts & Replacement Management
Penchin through her OEM partners (Severn Valves) provides a full range of valve and valve’s parts replacement. In order to ensure optimum capabilities, Penchin utilizes use-case insights to determine the most appropriate spare part assortments and offers a monitoring program to oversee consumption experience and data to drive procurement volumes.
