Hydraulic Power Unit - HB-7.5 Series
HB-7.5 Standard Hydraulic Power Unit
The HB-7.5 standard hydraulic power unit is a supporting hydraulic power station for split frame pipe cutting and beveling machines. It provides hydraulic power for pipe cold cutting, beveling and pipe end preparation before welding. With a compact and mobile structure, it is suitable for regular industrial pipeline maintenance, pipe installation, on-site repair and pipeline modification projects.
In field pipeline construction, split frame pipe cutting and beveling machines require stable hydraulic power to complete pipe cutting, beveling and end preparation. The HB-7.5 provides continuous hydraulic output, helping the cutting and beveling machine operate reliably under regular pipe diameter, standard wall thickness and general job-site conditions. Compared with manual cutting or thermal cutting, a hydraulic split frame cutting and beveling system helps reduce heat-affected impact, improve pipe end consistency and increase welding preparation efficiency.
The HB-7.5 is used in petrochemical pipeline maintenance, power plant pipeline repair, industrial pipeline installation, equipment maintenance, pipeline replacement and on-site welding preparation. It is a practical hydraulic power solution for users who need a stable and economical power unit for regular pipe cutting and beveling work.
Provides stable hydraulic power for split frame pipe cutting and beveling machines. Suitable for industrial pipe cold cutting, pipe end beveling and welding preparation. Standard hydraulic configuration with compact structure for routine maintenance and regular pipeline work. Works with split frame machines for pipe cutting, beveling and pipe end preparation. Mobile frame design makes it convenient for job-site transfer and pipeline installation projects. Suitable for petrochemical plants, power plant maintenance, industrial pipeline installation, equipment repair and pipeline modification.
