The bolt heating rod ZJ-17-1(R) uses 0Cr27A17Mo2 high temperature resistance alloy wire as the heating element and 1Cr18Ni9Ti stainless steel tube as the protective sleeve, which has excellent high temperature resistance and stable heating characteristics. It is suitable for the assembly and disassembly of steam turbine bolts and the assembly and disassembly of large bolts of other pressure vessels. |
Technical parameters: The rated working voltage of the electric heater is 220±20V. DC 100V, low voltage 50V; The center line straightness of the electric heater with an insertion length of less than 1m is not greater than Ø0.3mm; the center line straightness of the insertion length of 1-2m is not greater than Ø0.4mm; The diameter deviation of the insertion part is -0.20mm/-0.50mm; The length deviation of the insertion part is ±5mm, the heating length deviation is ±5mm, and the bottom cold end length is 25-30mm; The electric heater is required to heat evenly during use, and local overheating is not allowed. |
Product Features: Efficient and high-temperature resistant |
Applications: Specially used for heating hollow bolts in steam turbines and large machinery during installation and maintenance to meet the requirements of fastening and dismantling |
