Overview
Our state-of-the-art equipment, innovative engineering solutions, and technical expertise offers you specialised onsite machining and controlled bolting services. Our commitment to excellence is evident in our ability to deliver high-precision machining solutions and leak-free controlled bolting services across diverse industry sectors.
Onsite machining
Our onsite machining services provide cost-effective solutions when transporting component parts to a conventional machining facility is impractical. With in-house machine design, development, and manufacturing capabilities, coupled with cutting-edge equipment and technical expertise, we ensure a high standard of work. Our skilled technicians execute onsite machining to workshop tolerances and surface finishes, meeting clients’ specific mechanical requirements.
Controlled bolting
We offer a comprehensive range of tools along with highly experienced personnel capable of performing site surveys and recommending tailored solutions. With a proven track record of leak-free shutdowns and start-ups, our project management team supports site activities and all controlled bolting services. Our Flange Management processes ensure clarity, conciseness, and safe operational practices, combined with over 20 years of experience, making us your trusted partner for all bolting requirements.
