Hot Sale Hollow Bar! Hollow Bars are both hollow bars and seamless tubes. Hollow Bars are manufactured specifically for production of radially machined components. 
Hollow bars are used in production of valves and actuators (flowmeters, valves, filters, manifolds); pumps and compressor 
(vacuum equipment, hydraulic cylinders, pump housings); axes and shafts (rolls, guides, bushings, clamps, bearings); mechanical gaskets
 (seals, spacers, rings); connection components (fittings, flanges, couplings, connectors); measuring instruments (sensors, solenoids, resistors).



All of the abovementioned products can be used in various industries, as general machinery, chemical and petrochemical industry, 
shipbuilding industry, automotive industry, paper and paperboard industry, textile industry, food industry, etc.

The use of hollow bars minimizes material losses and reduces overall need in processing completely excluding operation 
of equipment for deep drilling. Chemical composition of steels used for manufacturing of hollow bars provides higher speed of 
cutting and long lifetime of cutting tools ensuring a defect-free surface after machining.
