Builder: DC PLAST eng. company
Items: + flange, PPH Valves VKD, PE100 pipes + fittings, PE100 sheets
Year: 2025-2026
Specifications:
Special tanks for storing and transporting chemicals were required for a copper production plant in the central-west of Bulgaria.
Due to the environmental conditions, the components had to be highly resistant to aggressive chemicals and corrosion.
- The tanks were made of polyethylene (HDPE), which is known for its excellent chemical resistance and durability.
- Process effluents -filtrates , weak alkaline and acid solutions.
- Working temperature = +60°C.
- Tanks are situated mostly outside (1-2 tanks inside).
Advantages for the FLANGE 3+:
- Mechanical resistance: Optimized and enhanced thanks to its new design that allows an excellent breaking load, outstanding elasticity properties and long life service.
- Ease of installation: Thanks to the bolts tightening sequence indications, the pins to clamp bolts and to its simmetry that allows bi-directional installation.
- Metal reinforcement is strategically concentrated at stress-prone areas of the backing ring (around holes and close to stub end area).
- Internal metal core to guarantee strength and mechanical resistance, covered by a PP-GR coating for chemical and corrosion resistance.
- The new wedge shape, as it has no gullies, reduces the collection of dirt, dust and liquids during the life of the product.
