Description
Professional HDPE Tank Welding & On-Site Repair Services in Gujarat
Nikunj Fibre Glass provides specialized HDPE Tank Welding Services (Thermoplastic Extrusion Welding & On-Site Chemical Tank Repair) based in Vapi, Gujarat. Whether you require on-site fabrication of custom chemical storage tanks, modification of existing pipeline nozzles, or emergency repair of cracked thermoplastic acid tanks, our certified technicians deliver high-integrity, leak-proof welding services.
Executing all work in strict accordance with German Welding Society standards (DVS 2207 and DVS 2209), we use advanced microprocessor-controlled extrusion welders with integrated preheating air shoes and precision butt fusion machines, ensuring 100% weld joint strength equal to parent thermoplastic material.
Our Welding & Fabrication Capabilities
- Extrusion Welding: High-output hand extrusion welding using matching PE-100 welding rod for thick tank wall joints and structural corner seams.
- Heated Tool Butt Fusion Welding: Mirror butt welding of large HDPE pipes and tank cylinders up to 1,200 mm diameter with automated data logging.
- Hot Gas Welding: Detailed hot air welding for tight nozzle gussets, level indicator ports, and internal dip pipes.
- On-Site Tank Leak Repair: Emergency patch welding and crack gouging of damaged chemical pickling and storage tanks without plant shutdown.
- Spark Testing Inspection: 100% weld seam quality assurance using high-voltage non-destructive spark testers (up to 30 kV) to detect micro-pinholes.

Frequently Asked Questions (FAQ)
Q1: Can an HDPE tank that is leaking concentrated acid be repaired on-site?
Yes, once the tank is neutralized and drained, our technicians grind out the crack, preheat the material, and apply a multi-pass extrusion weld reinforced with an HDPE patch plate, restoring full tank integrity.
Q2: How do you verify the quality and tightness of a plastic weld?
We run a high-voltage spark testing probe along every centimeter of the weld seam; any microscopic void or porosity triggers a bright visible spark, allowing immediate correction.
