Counter Weight Wax Scraper Structure

Wax scraper

The wax scraper is an important accessory for the floating roof tank for storing crude oil. It is installed at the lower part of the outer floating roof and rises and falls with the floating roof. Through the wax scraper close to the tank wall, the wax oil and grease attached to the tank wall are scraped off, so as to reduce oil and gas loss, purify the environment, and ensure the normal operation of the floating roof oil tank sealing device.

Structure performance of gravity wax scraper

The gravity wax scraper mainly relies on the gravity of the heavy hammer to transmit the adhesion force to the stainless steel wax scraper close to the tank wall through the wax scraping mechanism. The adhesion force is maintained at ≥380N/m and does not follow the floating roof to The tank wall spacing changes; the flexibility of the wax scraper is moderate, even if the out-of-roundness and local unevenness of the tank wall exceed the GBJ128-90 regulations, it can still be closely attached to the tank wall, so the wax scraping function is good.

According to the actual circular distance between the floating roof and the tank wall, our factory can provide three specifications of wax scrapers:
