Tube PE 4 X 7mm

Firstly Tube PE 4 X 7mm typically refers to polyethylene tubing used in chemical dosing systems. It’s designed to transport precise amounts of chemicals—often in water treatment, industrial processes, or laboratory setups.

• Material: Usually made from LDPE (Low-Density Polyethylene), known for flexibility and chemical resistance.
• Sizes:
  • Common dimensions include 4x7mm (4mm internal, 7mm external).
  • Available in rolls up to 100 meters.
• Applications:
  • Used on both suction and pressure sides of dosing pumps.
  • Suitable for chemical reagents, depending on compatibility.
• Pressure Ratings:
  • Burst pressure varies by size—e.g., 4x6mm LDPE can handle up to 50 Bar, while 8x12mm LDPE is rated for 30 Bar.
• Food-grade options: Some variants are certified for food-safe usage.
• UV Resistance:LDPE tubing is also UV resistant, making it suitable for outdoor applications.
• Chemical Resistance: It exhibits good resistance to acids, lyes, salts, and some organic solvents.

All in all Chemical dosing system is a complete set of equipment with dosing, mixing, transporting liquid and automatic control. It is also called chemical feed system or dosing machine.

Finally it is used for raw water of power plant, boiler feed water, oil field ground gathering and transportation dehydration treatment system, petrochemical dosing system and wastewater treatment system.
