Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang NORWESCO dari 3G Electric.
What materials are NORWESCO utility tanks made from?
NORWESCO utility tanks are rotationally molded from high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE). These materials are selected for their chemical resistance, impact strength, and durability. HDPE offers higher rigidity and temperature tolerance, while LLDPE provides greater flexibility and stress-crack resistance. The tanks are not made from polypropylene or PVC. The specific material used depends on the model; for example, the 45-gallon rectangular tank (MPN 43837-DS) is molded from HDPE. The tanks are not UV-stabilized as standard, so outdoor exposure may require additional protection.
Can NORWESCO tanks be used for potable water storage?
NORWESCO utility tanks are not certified for potable water storage. They are designed for non-potable liquids such as water for irrigation, industrial process water, chemical solutions, and waste fluids. The polyethylene material may leach compounds under certain conditions, and the tanks lack NSF or FDA certifications required for drinking water. For potable applications, tanks with appropriate certifications, such as those from other manufacturers, should be used. Always verify the intended use with the manufacturer's specifications.
What is the maximum operating temperature for NORWESCO tanks?
NORWESCO polyethylene tanks have a maximum continuous operating temperature of approximately 120°F (49°C) for HDPE and 140°F (60°C) for LLDPE, depending on the specific resin grade. These limits apply to the liquid contents, not ambient temperature. Exposure to temperatures above these thresholds can cause deformation, reduced strength, or accelerated aging. The tanks are not rated for hot liquids or steam cleaning. For high-temperature applications, consult the manufacturer's technical data for the specific model.
How do I install fittings on a NORWESCO tank?
NORWESCO tanks are supplied with a closed top and no pre-drilled holes for fittings. To install bulkhead fittings, vents, or drain valves, you must drill holes in the tank wall using a hole saw or drill bit appropriate for polyethylene. Use a bulkhead fitting with a gasket to seal the connection. The tank wall thickness varies by model; for example, the 10-gallon tank has a wall thickness of approximately 0.125 inches. Ensure the fitting is compatible with the tank material and the liquid being stored. Do not weld or solvent-bond fittings to polyethylene.
Are NORWESCO tanks stackable for storage or transport?
NORWESCO rectangular horizontal tanks are designed with flat tops and bottoms, allowing them to be stacked when empty. However, stacking capacity depends on the tank's structural integrity and the weight of the tanks above. For example, a 100-gallon tank (MPN 43294-DS) weighs approximately 35 pounds empty, and stacking multiple units may require a support frame. Total-drain tanks with sloped bottoms may not stack evenly. Always check the manufacturer's guidelines for stacking limits. Tanks should not be stacked when filled with liquid.
What is the warranty on NORWESCO tanks supplied by 3G Electric?
NORWESCO tanks are covered by the manufacturer's standard warranty, which typically covers defects in materials and workmanship for a period of one year from the date of purchase. The warranty does not cover damage from improper installation, chemical incompatibility, over-pressurization, or exposure to temperatures outside the specified range. 3G Electric acts as a distributor and does not extend additional warranties. For warranty claims, contact 3G Electric with the purchase details and product serial number. Proof of purchase is required.
