OTSG Maintenance Services
In critical industrial sectors such as the oil sands, the Once-Through Steam Generator (OTSG) is an essential asset for producing large quantities of high-pressure steam. Subjected to continuous operation under extreme thermal and pressure stresses, these systems are susceptible to material degradation, reduced thermal efficiency, and an escalating risk of component failure. Altex can work with you to get your OTSG back up and running again. It is critical that your unit has minimal downtime to ensure that production has the steam they need for maximum oil production.
At Altex Industries, Canada’s trusted partner for industrial lifecycle solutions, we understand that OTSG repairs are critical to keep production going. The consistent and reliable production of steam allows for the capture of heavy oil deposits (in SAGD production) and the extraction process. Our highly experienced OTSG crews are available to ensure that your OTSG is repaired quickly during unplanned maintenance events. By partnering with Altex, you are investing in the reliability of your operations, minimizing the risk of costly unplanned downtime, and ensuring that your OTSG continues to operate at peak efficiency for years to come
Pressure Regulatory Compliance
When Once Through Steam Generators (OTSG) require maintenance, it is vital that you coordinate your work with your local pressure regulatory authority. In Alberta in the Oil Sands, that authority is ABSA (Alberta Boiler Safety Authority).
Altex works collaboratively with ABSA to ensure that you are in compliance with ABSA’s requirements which ensures that all pressure vessels are operated and maintained safely.
Altex has many years of experience of working closely with ABSA, understanding the processes necessary, the paperwork required, and the steps to take to remain compliant. Trust Altex Industries to work with your pressure regulatory authority to help maintain your OTSG’s.
Experienced Supervision and Maintenance Crews
The most effective way to avoid costly unplanned downtime is to implement a comprehensive scheduled maintenance program. Altex Industries works closely with you to develop a customized maintenance plan that is tailored to the specific needs of your facility and the operating conditions of your OTSG. Our goal is to move you from a reactive “fix-it-when-it-breaks” approach to a proactive, predictive maintenance strategy that maximizes uptime and ensures the long-term reliability of your equipment.
Our scheduled maintenance programs are designed to be as comprehensive as possible, covering everything from routine inspections and calibrations to the planned replacement of wear components. By adhering to a regular maintenance schedule, you can have confidence that your OTSG is always in peak operating condition and that any potential issues will be identified and addressed before they can impact your operations.
