Protective sleeves (mounting, thermometer, insulating couplings) GZ are designed for mounting resistance thermometers, thermocouples, glass thermometers, bimetallic sensors, manometers.
Protective sleeves (mounting, thermometer, thermowells) GZ-001, GZ-002, GZ-003, GZ-004, GZ-101, GZ-102, GZ-103, GZ-104 (hereinafter protective sleeves GZ) are designed for the installation of resistance thermometers, thermoelectric converters (thermocouples), glass thermometers, bimetallic sensors, manometers. Protective sleeves GZ protect the mounted instruments from mechanical and chemical effects of the working environment and increased dynamic loads.
Mounting temperature sensors using protective sleeves GZ significantly extends the service life of these sensors. Thermometer sleeves can be mounted in pressure vessels, steam boilers, pipelines, tanks, and other facilities. Mounting is done using threaded (GZ-001, GZ-002, GZ-003, GZ-004) or welded connection (GZ-101, GZ-102, GZ-103, GZ-104).
To reduce thermal inertia, sleeves can be manufactured with a reduced diameter transition in the mounting zone of the sensor’s working area or other instrument mounted in the sleeve.
Thermometer sleeves are made with mounting threads: metric according to ISO 724, cylindrical pipe thread according to BSPP / ISO 228-1, and inch tapered thread according to NPT / ANSI-ASME B1.20.1. The mounting thread can be made upon customer's request according to other standards.
Protective sleeves GZ can be used together with temperature sensors models 002, 003, and 101.
Protective sleeves GZ are made from steel grade 12Х18Н10Т according to EN 10088. Upon customer's request, thermometer sleeves can be manufactured from other steel grades.
AISI 321 12Х18Н10Т 08Х18Н10Т heat-resistant, corrosion-resistant, high-temperature austenitic steel. It has high strength and durability. Used at temperatures up to 600 °C, and up to 350 °C in highly aggressive environments.
AISI 304 08Х18Н10 heat-resistant, corrosion-resistant austenitic steel. Used at temperatures up to 400 °C in environments with medium activity.
AISI 316L 03Х17Н14М3 corrosion-resistant austenitic steel. Used at temperatures up to 450 °C in most aggressive environments.
AISI 316Ti 10Х17Н13М2Т corrosion-resistant austenitic steel. Used at temperatures up to 600 °C in highly aggressive environments.
AISI 430 12Х17 heat-resistant, corrosion-resistant ferritic steel. Used at temperatures up to 400 °C in mildly aggressive environments.
12Х1МФ heat-resistant, resistant to prolonged high-temperature exposure perlitic steel. Used at temperatures up to 600 °C.
Protective sleeves GZ should be operated at flow velocities and pressures not exceeding the values specified in the tables for specific sleeve modifications. The maximum flow velocity and nominal pressure of the working environment are determined considering ensuring the static strength of the sleeve.
Thermometric sleeves GZ of all modifications are sealed. They are subject to acceptance tests with test pressure P_test and must be operated at working pressure P_work in accordance with GOST 3634-79.
