24-7 HEAT EXCHANGER
REPAIR SERVICES

With in-house mechanical and thermal engineering teams and full-scope NDE services, our seasoned heat exchanger professionals have the capabilities and tools to provide a comprehensive assessment of your shell and tube heat exchanger—and identify any issues that might interfere with the integrity, efficiency, and safety of the unit such as:

•  Pressure drop issues •  Erosion •  Corrosion •  Vibration wear & damage •  Differential thermal expansion issues •  Temperature cross / pinch point issues •  Mechanical issues

•  Tube blockage •  Fouling •  Leaks •  Flow rates •  Tube pitch issues •  Gasket failure •  More

You can rely on Metalforms' expert teams to rapidly diagnose and repair your heat exchangers for both common and highly complex issues, including:

The most common types of weld repairs we perform are weld build-up repair of eroded or corroded areas, removal of cracks and re-weld of those defects, and weld build-up for reclaiming gasket surfaces.  Any defects we find are removed by following the ASME Section IX qualified weld procedures.  

We work closely with our customers, to ensure their specific needs are met. 

We offer strip & retube services for all TEMA types of shell and tube heat exchangers as well as fin-fan type air cooled heat exchangers (ACHEs) - also referred to as air coolers.

With the ability to perform multiple, parallel workflows, Metalforms has the distinct advantage of offering multiple, simultaneous strip and retube projects.  Coupled with our ability to perform work around the clock, 24/7, we can meet your most demanding project needs!

Metalforms manufactures replacement parts to both standard and emergency schedules. With 24-7 engineering and fabrication teams, we can assist with your most urgent shell & tube heat exchanger parts and component needs including:

Our QC professionals inspect shell & tube heat exchanger gasket surfaces using sandblasting, which improves visibility of the base metals—and which is typically not possible with the standard inspection methods available at the plant.

Should any defects be detected, we review all findings with our customers to discuss options, prior to commencing any repairs.

Depending upon the nature of the defect found, our repair professionals can perform weld repairs using ASME Section IX qualified weld procedures and re-machine gasket surfaces to meet original specifications.

If damage is severe and repair is not possible—or simply not cost effective—we may recommend gasket replacement. 

Proper tube expansion is critical to maintaining efficient heat transfer and structural integrity in heat exchanger operations.

We have both the equipment and expertise to rapidly re-expand existing tube-to-tubesheet joints to repair seal integrity prior to installation / re-installation of tube bundles.  

Automated processes expedite repairs while promoting consistent, reliable outcomes. 

Metalforms manufactures shell & tube heat exchanger tube plugs for field maintenance and repair purposes, to seal off or block individual tubes that may be leaking, damaged, or in need of isolation due to operational changes—or as a precautionary measure during plant shutdowns and turnarounds to maintain system integrity and safety.

We maintain a stock of over 50,000 standard tube plugs in a variety of materials at all times, to support rapid response for all your tube plug needs.  Tube plugs are available for immediate shipment, with a minimum order of 25 required.

Our seasoned teams utilize a variety of non-destructive examination (NDE) methods to inspect both newly fabricated heat exchangers and other equipment as well as to diagnose issues with in-service and used equipment to ensure optimal quality  efficiency, reliability, and safety, including:

● Radiography Liquid Penetrant
● Magnetic Particle
● Brinell Hardness
● PMI (XRF Analyzer)
● Hydro Testing
● In-house PWHT Oven
● 8’-0” X 8’0” X 20’-0”
● In-house Local Stress Relieving
● Detailed Inspection of Existing Units

Metalforms is authorized by ASME to apply certification mark for U, S, and PP; and authorized by the National Board Inspection Code to apply R, NB and H stamps.

Whether you need a single part or a complete shell and tube heat exchanger, all products confirm to the following industry standards: ASME Boiler and Pressure Vessel Code Section VIII Division I, TEMA, National Board, API 660, 661, 605, and NACE where applicable—in addition to individual customer  specifications.
