Plugging Stainless Steel Belt Authenticity Identification Method
- Jun 22, 2019 -

In the industry, the steel strip tensioning technology in the industry uses the stainless steel strip of the material to be bundled in the pipeline leakage part. It needs to maintain the tightening effect for a long time. If the counterfeit stainless steel belt is purchased on the market, the stainless steel belt will be blocked after the plugging. The long stretch as the elastic band causes the second leakage or multiple repeated leaks in the pipeline leakage. The reason for this problem is that the forged stainless steel belt is not known for the true sealing of the stainless steel belt. 304 or 306 stainless steel plates are used as plugging stainless steel strips after cutting. These steel strips are not produced according to the standard of plugging stainless steel strips, so the hardness is not enough, there is tightness, and the thickness of the standard plugging stainless steel strip is 1.2mm. , hardness 800, plugging stainless steel bandwidth 30mm plugging pressure 2.9MPa, because of high hardness, no elastic force, the bundle will not change after the leak. Forged with 1.5mm, hardness of 400, forged stainless steel bandwidth 30mm plugging pressure 1.8MPa, but due to the limitations of its own material formulation, after a few days after the bundle is leaked to the pipeline, the steel will change Long, leading to repeated leaks.

In addition, the method of judging: standard special plugging stainless steel belt with G5-30 or G9-60 strong tensioner can be tightened to easily block the leak, use the market to buy ordinary tensioner to pull the standard special plugging stainless steel belt will pull the tight Pull.
