On one of the compressor stations of LLC "Gazprom Transgaz" specialists of CJSC "Plakart" works on application of combined heat-resistant corrosion-resistant aluminum-containing coating "Spramet" on the exhaust shaft pumping unit.
Work was carried out with the forests at an altitude of 32 meters above the ground. The works were made in the station of "Gazprom" in a short time during the current GPA and repair without dismantling the chimney.
Pipe GPA coated Spramet
Metal chimneys and exhaust shafts boilers and gas pumping units (GPU) are very difficult to protect the paint or polymer compositions: the temperature drops to 600 ° C quickly burn and leave a protective coating pipe defenseless against corrosion. Besides, the thermal heating carbon steel to 250 ° C, is rapidly becoming the pipes discoloration arising from oxidation.
Deposition of aluminum-containing protective coating solves the problem of the protection tube for 15-20 years.
Covering "Spramet" applied at the facility LLC "Gazprom Transgaz", by heating the material forms a tube intermetallic layer of white color which has an extremely high resistance to corrosion and wear out very slowly at atmospheric conditions.
Also important is a decorative effect created by thermal coatings "Spramet" ZAO "Plakart." To bring the aesthetic appearance of the metallic logo of Gazprom, gas-flame method were coated brass.
