Description

Heavy-Duty PPH Chemical Storage Tanks

Nikunj Fibre Glass is a premier manufacturer of custom-engineered PPH Chemical Storage Tanks and spiral-wound process vessels in Vapi, Gujarat. Since 1992, our engineering team has designed and delivered industrial plastic storage equipment to chemical, pharmaceutical, and steel processing industries across India.

Polypropylene Homopolymer (PPH) provides unmatched chemical resistance against concentrated mineral acids and corrosive reagents. In addition, its high stiffness-to-weight ratio ensures superior structural stability even under full hydrostatic head pressures. Specifically, our tanks operate continuously up to 100°C, making them an ideal replacement for rubber-lined steel vessels.

Precision Thermoplastic Tank Fabrication

We manufacture PPH storage tanks using state-of-the-art spiral winding extrusion and butt-fusion welding technology. For example, our manufacturing capabilities cover capacities from 500 Liters up to 50,000 Liters in vertical cylindrical, horizontal cylindrical, and rectangular configurations. Consequently, chemical plants receive storage equipment engineered specifically for their storage volume and space constraints.

Key Advantages of PPH Storage Tanks

Structural Integrity & Chemical Security

• Seamless Spiral Construction: Our PPH cylindrical tanks feature spiral-extruded seamless shells without vertical weld seams. Therefore, hoop stress is distributed evenly with zero risk of seam splits.
• Total Resistance to Concentrated Acids: PPH resists aggressive chemicals including 33% Hydrochloric Acid (HCl), 98% Sulfuric Acid (H2SO4), Nitric Acid (HNO3), and Caustic Soda (NaOH).
• High Temperature Capability: While standard HDPE tanks soften at 60°C, our PPH vessels operate safely up to 100°C under continuous hydrostatic loading.
• Corrosion-Free Exterior & Interior: Unlike metal tanks, PPH requires no external painting, anti-corrosive coatings, or internal rubber linings throughout its 25+ year lifespan.
• Integrated Process Fittings: We equip our tanks with heavy-duty flanged nozzles, level gauges, top manholes, lifting lugs, and anchor brackets welded with double-V extrusion passes.

Frequently Asked Questions (FAQ)

Common Technical Inquiries

Q1: What makes PPH Chemical Storage Tanks superior to HDPE storage tanks?
While HDPE is suitable for ambient temperatures up to 60°C, PPH delivers superior tensile strength and heat stability up to 100°C. For hot chemical storage, exothermic dilution of sulfuric acid, or hot pickling baths, PPH maintains structural stiffness without creep or buckling.

Q2: How are PPH chemical storage tanks designed for high specific gravity acids?
We engineer each PPH tank in accordance with DVS 2205 standards based on the exact specific gravity (SG) and operating temperature of the stored fluid. For dense acids such as 98% H2SO4 (SG 1.84), we reinforce the shell wall thickness and weld heavy reinforcement ribs to ensure long-term factor of safety.

Q3: Does Nikunj Fibre Glass offer custom tank nozzles and accessories?
Yes, Nikunj Fibre Glass equips each PPH tank with customized ANSI or DIN flanged connections, manholes, vent nozzles, level switches, level gauges, ladders, and top handrails tailored to your plant piping layout.
