The national standard instructs you to set the technical parameters of the glass steel septic tank(Two)
Technical requirements for the non-seepage of the tank
Leakage test - requires that the glass steel septic tank is free of leakage and no obvious deformation after filling the water.
Test method: to fix the septic tank in backfill or other way, fill the water with water after sealing, place 24h observation, no leakage and no obvious deformation.
The water absorption rate can effectively reflect the density of the tank and the surface
Test method: measured by GB/T 1462.
Impact strength - the strength is very important for the glass steel septic tank, which is related to whether the surface of the glass steel septic tank will crack or damage.
Test method: use a quality 2000g steel ball above the center part of the tank, drop from 2m height freely, and inspect the tank surface at the steel ball impact tank. The falling position of the ball should be avoided to ensure that the test method can be carried out normally due to a clear hole in the center of the tank.
Technical requirements for more than 70 years of service life:
The structure of the septic tank should not be enhanced with metal materials. (different materials have different life spans, such as metal tubes, round tubes, etc., whose life span is shorter than that of FRP, and metal materials must be eliminated.)
Water resistance - a fundamental guarantee of the reliability and longevity of the glass steel septic tank (the storage tank used for the inspection of long-term storage of liquids).
