F4 manufactures hot tapping machines equipped with a pressure balancing system featuring compensation cylinders. This system equalizes pipeline and sea pressure, reducing stress on internal components and extending the tapping machine’s lifespan. These machines are designed for high-pressure and subsea tapping operations, with capabilities to handle pressures up to 2175 psi (150 bar).

F4 manufactures lightweight and portable tribar hot tapping machines, ideal for low-pressure utility services such as chilled water pipelines in air conditioning systems or air/nitrogen pipelines in pharmaceutical and food processing plants. These machines enable bypasses or branching in pipelines and are particularly suited for areas with space constraints, such as malls, hotels and data centers. Thanks to their light weight and compact design, tribar machines can be manually installed without the aid of lifting equipment and easily transported to any floor in high-rise buildings via elevator.
F4’s state-of-the-art compact hot tapping machines are designed to facilitate repairs or replacements on pipelines without requiring shutdowns, ensuring continuous operation.

F4 designs and manufactures worm gear-driven machines and hydraulic hot tapping machines equipped with a compact, sophisticated gearbox. F4 is the first company in India to design, manufacture and supply air-driven (worm gear-driven) hot tapping machines to both public and private sector oil and gas companies in India.
