After finishing the plastic lining processing technology, in order to ensure its quality and practicability, manufacturers will perform acceptance before leaving the factory. There is a certain inspection standard for the acceptance. The following will introduce the acceptance of the equipment standard:
1. Eliminate plastic residues in areas not lined with plastic to ensure the appearance of the product.
2. During the installation of the pipe plug, control the heating temperature of the pipe plug to prevent plastic loss at the installation place of the pipe plug.
3. When transporting, storing, and installing the product, be sure to protect the plastic lining from being damaged.
4. The thickness of the plastic lining is 3 ~ 5mm, and there are no pores or dense pores that penetrate and are close to the lining.
5. The flatness of the lining plastic layer on each sealing surface is required to be less than 1mm to ensure the sealing performance of the pressure test.
6. It is necessary to check whether the joint seat holes are blocked. The standard is that no blocking is allowed.
7. The surface of the plastic lining of the equipment should be smooth, flat and uniform in color, and no cracks or peeling are allowed.
8. Construction and inspection shall be carried out according to the schematic diagram of the product. The plastic-lined area of the product shall be completely covered without omission to prevent local corrosion.
The plastic lining equipment mainly checks whether the quality of the product meets the standards and whether the product meets the customer's requirements. When the user checks, it is necessary to check the acceptance to find out if there is a problem. Future use is troublesome.
