We can re-rate, adjust, upgrade, or reconfigure your existing shell and tube heat exchangers or ASME pressure vessels to accommodate new operating conditions or applications in midstream oil and gas production and processing.
Rerating:
After a comprehensive assessment of your unit, we’ll collaborate with you to identify any necessary modifications before proceeding with any work. If your unit already meets the updated requirements or after modifications have been completed, we will provide all the required documentation to verify that the existing design will continue to perform safely and efficiently under the new specifications, as required by both owners and regulators.
Modifications:
Whether re-rating is needed or not, we are equipped to assist with a wide range of repairs, alterations, or upgrades to shell & tube heat exchangers and ASME pressure vessels. This includes changes to design, configuration, materials of construction, or the addition of new features to ensure optimal performance for your operations.
All modified units will meet all applicable ASME, NBIC, TEMA, and API codes and standards.
