Description

GIS Engineering & Environmental Services successfully completed the design, fabrication, and installation of a stainless steel process plant for a high-capacity chemical manufacturing facility. The project involved specialized stainless steel piping, tank fabrication, and process system integration to meet the strict corrosion resistance and hygiene standards required in chemical production environments.

Client: Confidential Chemical Manufacturing Company

Project Title: Stainless Steel Plant Installation – Chemical Processing Facility
Location: Tanzania
Sector: Chemical Manufacturing & Industrial Processing
Service Category: Stainless Steel Fabrication, Piping & Equipment Installation, Plant Engineering

Problem

The client required a durable, high-grade stainless steel system to handle aggressive chemical substances under pressure and temperature variations. Core challenges included:

• Need for corrosion-resistant material with high structural integrity

• Precision welding and finishing to maintain purity in chemical processes

• Coordination with imported machinery and limited fabrication window

• Compliance with chemical plant safety and environmental standards

Solution

GIS delivered a custom-engineered stainless steel solution, including:

• Design and fabrication of SS316L reactor tanks, storage vessels, and pipe networks

• TIG welding and orbital welding for high-purity joints

• Installation of chemical-resistant valves, nozzles, and instrumentation

• Mechanical integration with pumps, filters, and dosing systems

• Safety shielding and spill containment systems around process units

Process

• Material Sourcing & Pre-Fabrication
  Procured certified stainless steel sheets, pipes, and fittings meeting ASTM standards.

• Precision Fabrication & Assembly
  Used CNC cutting, rolling, and orbital welding to build tanks, skids, and pipelines.

• Surface Treatment & Passivation
  Conducted acid cleaning and passivation to enhance corrosion resistance.

• Onsite Installation & Testing
  Transported fabricated units, assembled and tested the full system on location.

• Commissioning & Training
  Pressure-tested pipelines, ran dry and wet tests, and trained client’s technical team.

Results

• Full stainless steel process system delivered and commissioned on time

• Improved chemical production efficiency and corrosion control

• Zero contamination across production line due to high-grade finishing

• Compliance with OSHA, NEMC, and international chemical safety codes
