Visakhapatnam, AP India (PressExposure) October 02, 2007 -- Project Sales Corp, authorised agents in India for Schaaf GmbH & Co. KG will introduce the ExpaTen bolts to the Indian customers at INMEX INDIA, the International Exhibition on Shipbuilding in Mumbai, India to be held between October 3-5, 2007.
SCHAAF is leading the way with ExpaTen bolts in order to revolutionize detachable flange connections of propulsion shafts of the shipbuilding industry. Not only are the bolts 100% non-positive and form fitting, which transfers high torque, but even after high stress they can be easily disassembled and reused. The bending and rotating resistant connection absorbed shock like changes of revolutions, torque as well as turning direction dependently. The system is made of heat treated steel, which is a safety plus during torque transfer. The safety factor in comparison to regular screws is 5. ExpaTen is easy to handle since all tools and hydraulic high-pressure pumps for assembly and disassembly are adjusted to the system. ExpaTen is certified by well-known buyers.
SCHAAF is certified in accordance with DIN EN ISO 9001:2000 and, in addition, fulfils all requirements of all other classification societies.
Expansion and pretensioning result in the following advantages compared to conventional bolts:
High torque transmission, completely free from backlash 100 % positive locking and frictional connection Torsionally and flexurally rigid connection even with sudden changes in the rotational speed, the torque, or direction of rotation Reduction of flange dimensions possible due to fewer number of bolts for torque transmission Maximum torque transmission in minimum space More security Simple and quick installation and removal of ExpaTen even after years of use and in restricted spaces Reusable after removal Cost-saving
Areas of Application
SCHAAF ExpaTen Bolts are the optimum solution wherever high forces (torques) must be transmitted and, at the same time, easy removal must be ensured.
