MCCS International, in partnership with Sealing and Bolting Technologies LLC, provides specialised breech-lock exchanger services to worldwide oil, gas, and petrochemical plants. With over 250 installations across five countries, our team has a proven track record of installation, maintenance, commissioning, and operational optimisation of breech-lock exchangers.
Our approach ensures leak-free performance, operational reliability, and extended equipment lifespan, while complying with international safety and engineering standards for onshore and offshore platform maintenance.
Proper planning is essential for breech-lock heat exchanger servicing. Click on one of the following drop downs for more information on the service MCCS engineers provide.
Pre-Installation Engineering & Planning
Detailed review of design documents and manufacturer specifications
Analysis of flange, gasket, and bolting requirements
Joint integrity planning, including bolt load calculations
Risk assessment and development of safe work procedures for handling and lifting
Pre-installation orientation and training for client or operational teams
This preparation ensures that each breech-lock heat exchanger will be installed with the right alignment and torque, which supports safe and reliable operation.
Installation Engineering & Planning
Our teams manage the complete installation process, with detailed records of torque and bolt load for full traceability and certification.
Mechanical fit-up of breech-lock components
Precision alignment of shell, tubes, and covers
Controlled assembly using calibrated torque and tensioning tools
Verification of bolt patterns, gasket seating, and compression
Hot/thermal alignment checks to account for operational expansion
Sealing Technology
To ensure your heat exchanger maintenance maintains a leak-free performance, our services include:
Selection of suitable gasket materials based on process media, temperature, and pressure
Verification of flange surface finish and preparation of sealing faces
Controlled gasket compression using calibrated torque or hydraulic tensioning
Identification and mitigation of common sealing challenges (e.g., creep, relaxation, misalignment)
This ensures joint integrity is maintained during startups, shutdowns, and operational variations.
Bolting & Joint Integrity Technology
MCCS applies the following advanced bolting methods to secure heat exchangers. We do this to maintain joint integrity and extend equipment service life.
Hydraulic bolt tensioning for critical and high-load connections
Torque control using calibrated torque wrenches
Proper bolt sequencing and pattern application for uniform load distribution
Verification of bolt elongation and flange gaps
Inspection for signs of stress, fatigue, or loosening
This can reduce the risk of leaks or unplanned shutdowns from joint integrity failure.
Heat Exchanger Maintenance & Troubleshooting
Comprehensive heat exchanger maintenance helps minimise downtime and support the safe, long-term operation of onshore and offshore platforms. MCCS can provide:
Routine inspection, bolt retorquing, and joint integrity checks
Gasket replacement and verification of sealing surfaces
Mechanical cleaning and chemical flushing of tubes
Leak investigation, diagnosis, and rectification
Predictive maintenance advice to improve future reliability
Commissioning & Functional Testing
Following installation or maintenance, MCCS performs full system commissioning to verify heat exchanger readiness and operational integrity. The following steps ensure your breech-lock exchanger meets design specifications and is ready for operation:
Pressure testing, hydrotesting, and leak detection
Temperature and operational ramp-up validation
System alignment verification under load
Performance checks to confirm heat transfer efficiency and operational stability
