Chemical Thermoplastic Piping

Chemical Thermoplastic Piping, Duct & Tank Solutions — Delta Saras

Overview

Delta Saras provides engineered thermoplastic supply/Fabrication and Installation for chemical handling, ventilation ducting and storage in steel manufacturing plants. Our solutions—spanning piping spools, process ductwork, and chemical storage/processing tanks—are designed for corrosion resistance, safe material handling, and long-term reliability in the aggressive environments typical of steel production (pickling lines, descaling, surface treatment, wastewater handling, and neutralisation systems).

We combine industry-proven materials, factory-controlled fabrication, on-site jointing expertise, and full-lifecycle services (Supply, fabrication, installation, testing, and after-sales support) to minimise downtime and total cost of ownership for steel manufacturers.

Key Deliverables

1. Feasibility & Materials Selection
  • Process chemistry review and material recommendation (PP/PPH, PVC-U, CPVC, PVDF, HDPE, lined FRP).
  • Corrosion allowance and compatibility studies.
2. Fabrication & Prefabrication
  • Shop-fabricated thermoplastic spools and duct sections to reduce on-site work.
  • CNC machining, moulded fittings, flanged terminations and fabricated tank.
3. Jointing Technology & Field Joining
  • Extrusion Welding — high-quality butt and fillet welds for PP, PPH, PVC-U.
  • Hot Gas Welding — for controlled, strong thermoplastic welds in tight spaces.
  • Socket/Spigot Fusion & Electrofusion — commonly used for HDPE systems and select piping runs.
  • Mechanical Flanges & Gasketed Connections — for removable sections, instrumentation taps and maintenance zones.
  • Adhesive Bonding — for specific material combinations and tank liner applications.
4. Installation & Commissioning
  • Site supervision, specialised jointing and testing (hydrostatic, pneumatic, vacuum where applicable).
  • Pre-commission cleaning, passivation and leak testing with documented sign-off.
5.Inspection, Maintenance & Retrofit Services
  • Scheduled inspection plans, predictive maintenance guidance and on-site repair services.
  • Retrofit/replace strategies for ageing metallic systems with thermoplastic upgrades.

Key Capabilities

  • Material expertise: In-house material selection for aggressive chemistries, high temperature pickling lines and abrasive slurries.
  • Fabrication capacity: Dedicated thermoplastic fabrication shop with CNC fittings, welding booths and precision glueing stations.
  • Jointing quality control: Trained welders certified to Delta Saras welding procedures, NDE (visual, destructive sample where needed) and weld records for traceability.
  • Modular design approach: Prefabrication of large modules (skids, tank panels, duct banks) to accelerate site erection and minimise plant shutdown durations.
  • Full documentation: P&IDs, isometrics, ITPs (Inspection & Test Plans), FAT checklists and O&M manuals aligned to your plant quality systems.
  • Safety & compliance: Adherence to recognised standards and plant safety rules. We develop method statements and risk assessments for confined spaces, hot works and chemical handling.

  • Hydrostatic & pneumatic testing procedures with signed ITPs.
  • Dimensional control, flange face flatness, bolt torque records and certificate pack delivery.
  • Material traceability and certificates for resin and fabricated components.

Other Sectors Served:

Delta Saras has delivered thermoplastic solutions across process-heavy industries. For steel manufacturing, we serve:

  • Integrated steel mills and mini-mills
  • Pickling and cold-rolling lines
  • Galvanising and surface treatment plants
  • Auxiliary utilities: effluent treatment plants (ETP), chemical dosing and wastewater systems

(Our past projects include pickling header replacements, acid-neutralisation tank systems, ETP transfer lines and turnkey ducting for corrosive exhaust — references available on request.)

Key Benefits to Your Plant

  • Extended service life vs. unlined metallic systems in corrosive zones.
  • Reduced maintenance frequency and simplified repair strategies.
  • Faster installation through modular fabrication—less production disruption.
  • Lower overall lifecycle cost where process chemistries aggressively attack metals.
  • Single-vendor accountability from design to commissioning and warranty.
