Polyethylene ( PE ) Pipe Groove Tape

Polyethylene ( PE ) Pipe Groove Tape Is An Industrial Anticorrosive Pipe Groove Tape Composed Of Polyethylene Base Material And Adhesive Layer. The Detection Project Of Polyethylene Anti-Corrosion Pipe Groove Tape Is To Detect The Anti-Corrosion Coating Quality Of Polyethylene Anti-Corrosion Pipe Groove Tape. Specific Test Items. It Can Be Divided Into Two Steps, One Is The Process Quality Inspection, The Other Is The Finished Product Inspection.

1. Field Cases:

We Provide a Batch Of Polyethylene Anti-Corrosion Pipe Groove Tape With Thickness Of 1.1mm. After The End Of The Customer's Construction, Stop Measuring The Thickness Of The Anti-Corrosion Coating. Most Of The Test Results Are Less Than 1.1 Mm, And The Thinnest Part Is Less Than 1.0 Mm.
On The Spot, The Thickness Of Anticorrosive Pipes With The Same Thickness From Other Manufacturers Was Measured, And The Results Were Basically Different, And The Thickness Was Less Than 1.1 Mm. What Causes The Problem?

2. Analysis Of Site Factors:

There Are Three Factors That Lead To The Shrinkage Of The Thickness Of The Anti-Corrosion Coating. One Is That The Thickness Of The Anti-Corrosion Pipe Groove Tape Becomes Thinner Due To Over Stretching In The Construction; Second, There Are Problems In The Detection Equipment; Third, There Are Problems In The Detection Methods.
According To The Field Analysis, The Factors Of The Anti-Corrosion Pipe Groove Tape Due To Over Stretching Were Firstly Removed. Through The Detection Of The Thickness Of Other Objects, The Problems Of The Detection Equipment Itself Are Eliminated. So The Rest Is The Problem Of Detection Methods.

3. Analysis Of Detection Methods:

The Instrument For Detecting The Thickness Of Anticorrosive Coating On Site Is Electronic Thickness Gauge. After Pressing The Probe Of The Thickness Gauge On The Surface Of The Anticorrosive Coating, The Test Results Will Be Directly Displayed On The Display Screen.
After Careful Inspection, It Can Be Found That The Probe Of The Electronic Detector Is a Small Metal Platform With a Small Bottom Area. As The Adhesive Layer Of The Pipe Groove Tape Is Soft, It Has Mobility. When The Probe Of The Thickness Gauge Is Pressed On The Surface Of The Anticorrosive Coating, The Contact Area Between The Probe And The Anticorrosive Coating Will Collapse. Thus, The Measured Thickness Is Less Than The Practical Anticorrosive Coating Thickness.

4. Treatment Method:

After The Above Analysis, We Only Need To Deal With The "Collapse" Problem Of The Contact Surface Between The Probe And The Anticorrosive Coating, And Then We Can Deal With The Inaccurate Measurement Results Of The Thickness Gauge. We Can Pad a Flat Hard Film (Glass Or Plastic) On The Surface Of The Anticorrosive Coating, And Then Detect The Thickness Of The Hard Film And The Total Thickness Of The Anticorrosive Coating And Hard Film Respectively. The Standard Thickness Of Anticorrosive Coating Can Be Obtained By Subtracting The Total Thickness Of Anticorrosive Coating And Hard Plate From The Thickness Of Hard Plate Itself. Here, The Hard Chip Mainly Plays The Role Of "Anti Collapse".

5. Final Results:

After Readjusting The Detection Method, The Thickness Of The Anti-Corrosion Coating Is 1.1 Mm, And The Error Is Within The Allowable Range.
