With 18 years remote area multidiscipline experience, BLJ In-situ provides high value solutions in a cost effective way, across industries and markets.
Our recently completed projects are a testament to our ability to consistently provide clients with a leak-free startup for turnaround, through the Controlled Bolting Services we offer:
Bolt torquing / Torque tightening
Bolt tensioning / Bolt tensioners
Bolt load calculations & Flange stress analysis
As part of our Controlled Bolting Services, we also provide bolt tensioning.
Bolt Tensioning is the process of stretching the bolt by applying an axial load directly onto the bolt. Bolt tensioning is accurate and offers time-saving on larger flanges. It is commonly used for bolt sizes 1.1/2” diameter and above.
Generally, 50% of studs are tensioned simultaneously, applying an even and accurate load on the gasket, thus providing the best chance for an effective long-term seal. We stock Bolt Tensioners to cover up to 4” diameter bolts. We provide bolt load calculations and flange stress analysis.
BLJ In-situ Solutions is certified and registered by TQCS International Pty Ltd to ISO 9001:2015 Quality Management Systems standard. All work undertaken by our technicians is executed in accordance with its Quality Management System processes.
As a result of our specialised Controlled Bolting services, BLJ In-situ Solutions has an excellent reputation as a Mechanical Maintenance and Shutdown Service Provider. To learn more about our Bolt Torquing and Bolt Tensioning services, take a look at our FAQs below.
Controlled bolting is the technique of applying an accurate torque load to a mechanical joint in order to assure joint integrity. Because bolted joints are frequently one of the most prevalent parts in industrial components, the durability of each connection is critical. At BLJ, we have specialised methods for accurately and precisely tightening or loosening bolts in various mechanical applications.
Controlled bolting is used in various situations where precise and reliable bolted connections are critical. It is employed during equipment assembly, maintenance, and repairs in industries such as oil and gas, power generation, manufacturing, construction, and more. Controlled bolting ensures accurate tightening, safety, and optimal performance of bolted connections.
Controlled Bolting involves using specialised tools and equipment, such as hydraulic torque wrenches or tensioners, to achieve specific torque or tension levels for fasteners. This technique ensures that bolts are tightened or loosened according to precise specifications, promoting safety, reliability, and optimal performance in machinery and structures.
Controlled bolting is essential in industries where secure and reliable bolted connections are crucial. Properly tightened bolts provide better load transfer and stability, enhancing the overall performance of equipment or structures. This can improve productivity, reduce wear and tear, and increase equipment lifespan. By ensuring accurate and consistent bolted connections, controlled bolting helps prevent costly repairs, rework, or equipment damage caused by improper bolt tightening. It also minimizes the risk of unplanned downtime, saving businesses valuable time and money.
Controlled Bolting is a highly specialised and difficult procedure where the knowledge and experience of a trained professional is required. Our trained BLJ technicians understand the complexities involved in bolting applications, including different bolt types, torque requirements, and equipment specifications. Their expertise ensures that the bolting process is carried out correctly and efficiently. Controlled bolting involves working with high-pressure tools and heavy machinery in which improper maintenance could lead to equipment failure, structural damage or harm to onsite personnel. The BLJ team can prevent unnecessary damage to your equipment, quickly assess bolting requirements, select the appropriate tools, and complete the job with precision. This efficiency translates into cost savings by reducing labour costs and avoiding potential rework or equipment damage caused by improper bolting.
