Before operation, test determines that glass steel pipeline causes the external pressure (critical pressure) of pipeline unstability to be greater than 60MPa.Injecting sealant (glue rod) is heated to 90 DEG C-120 DEG C before using, and injects successively along hole for injecting glue, and when operation, injecting glue is walked glue laminated power and is controlled at below 30MPa, and after full glue, injection pressure rises to 40MPa and stops note, seals hole for injecting glue with bolt.
Step 8: seal clamp is wrapped up completely with slip-type plastics gum cover, included 5kg butter is anticorrosion.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
