Valve Repair

Valve Repair & Overhaul - All valves are stripped to their fundamental components, cleaned, and tested before being reinstalled. Damaged flange faces are inspected and machined if needed. Service providers repair and overhaul valves this way.

Valve Repair & Overhaul

Before being reinstalled in the valve, all valves are stripped down to their most basic components, cleaned with proper methods, and tested to ensure they are within the manufacturer's tolerance. Flange faces that have been damaged are carefully checked and, if necessary, machined. A valve is fixed and overhauled in this manner by a service provider.

How To Approach Valve Overhauls And Repairs?

As part of an overhaul or repair of your valves and equipment, a service provider would normally do the following steps:

• A first evaluation of the equipment, which may involve diagnostics or testing to identify its present status.
• A complete analysis and suggestions detailing the work needed to guarantee the equipment's continuing safe and effective functioning.
• A thorough examination and dismantling of all valve components to determine their condition.
• After that, the valve is rebuilt, using either original or extra components as needed. We either produce or purchase spare components from specialized vendors.
• If necessary, additional testing is performed to ensure that all equipment is safe and functional before it is returned to service.
• All necessary paperwork is completed, including any warranties for the service performed.

Modifications of a Valve

When necessary, a service provider's expertise and creativity of industrial equipment allow them to adjust valve design, increasing their adaptability or, in certain cases, converting them for other services/purposes to the project's advantage. All design and calculation operations are supervised and implemented by the engineering team, which might take place on-site or at one of their certified machine shops.

They may alter current stock to achieve significant cost savings and the ability to reduce system downtime by reducing factory lead time situations and producing timely and accurate solutions.

Testing of Valves

In the Energy Industry, performance testing in whatever form is the pinnacle of determining whether or not equipment is fit for its purpose. While testing in-situ is the most accurate method of determining valve performance, the diversity of service provider facilities allows them to recreate a variety of different service settings to give the most comprehensive testing service available.

A service provider can offer sophisticated testing in addition to the basic API & EN hydrostatic and pneumatic valve leak testing to suit the most demanding applications and criteria of their clients. The following is a list of a service provider's extensive testing capabilities:

• Hydrostatic Testing
• Pneumatic Air Testing
• Nitrogen Gas Testing
• Torque Testing
• Functional Tests
• Fugitive Emission Tests
• Cavity Relief Tests
• Actuated Assembly FAT
• Third-Party inspection
• Double Block & Bleed Testing
• Non Destructive Examination
• PSV Pop Test
• PMI
• PR2 Qualification Testing
• Hyperbaric Testing
• Firesafe
• Cryogenic Testing down to -196 °C
• Corrosion Tests
• Mechanical tests, hardness tests, and Impact tests
• Ferrite Check according to E562
• Micro Examinations by Electronic Microscope

Painting of Valves

Valves and related pipeline equipment can withstand some of the most corrosive environments conceivable. Valves that are utilized near or on the water are continually exposed to salty environments. Any number of chemicals are likely to come into contact with the outside surfaces and fasteners of chemical, pulp, and other processing factories, creating ideal circumstances for corrosive build-up on metallic surfaces.

The product's proper coating is just as important as the pressure test in determining its suitability. Valves and related equipment can be blasted and painted to any industry-specified finish and color. Painters must comply with NACE and NORSOK criteria to fulfill any additional customer demands, which may include, but are not limited to, adhesion testing, holiday tests, and various levels of NACE inspection.
