Treating Method

Before applying any anti-corrosion treatment, TMCO vessels undergo a rigorous sandblasting process to prepare the steel surface for optimal coating adhesion. Our sandblasting adheres to clause 4.3 of SABS 064/ISO 8501/1, achieving a grade of SA 2.5, ensuring an angular blast profile that meets industry standards.

The interior of the vessels is treated with Carboguard 545, a three-coat epoxy polyamide system, each layer applied at 150 microns. This fast-drying, water-resistant coating can handle temperatures up to 90°C, making it ideal for hot water storage.

Externally, vessels receive two coats of Jotun Hardtop Flexi, a high-performance aliphatic acrylic polyurethane, providing superior flexibility, impact resistance, and long-lasting protection in atmospheric environments. Our treating method ensures maximum durability, corrosion resistance, and vessel performance.

Pressure Ratings

TMCO offers two standard vessel ranges with robust pressure ratings to meet diverse system requirements.

Our ECONO vessels are designed to handle operating pressures of up to 400kPa

Our OPTIMA range is engineered for pressures up to 600kPa.

Each vessel is rigorously pressure-tested to 1.5 times its designated operating pressure, ensuring reliability and safety.

For specialized needs, we also manufacture custom vessels capable of withstanding pressures of up to 1000kPa.

This flexibility in pressure ratings makes TMCO vessels suitable for a wide range of applications, ensuring performance under varying operational demands.

Quality Control

At TMCO, we implement stringent quality control measures throughout the manufacturing process to ensure each vessel meets the highest standards of performance and reliability. 

We begin with a thorough material inspection, verifying that all components meet specifications for strength, durability, and corrosion resistance. 

Welding quality assurance ensures all joints are defect-free and structurally sound, while dimensional accuracy checks confirm the vessel conforms to design requirements. 

Our vessels undergo rigorous pressure testing to verify their ability to withstand designated pressures without leakage. Both interior and exterior finishes are subject to surface finish inspection and coating evaluation, ensuring proper adhesion and corrosion protection. Additional functional testing is performed to verify operational performance. 

Each vessel is delivered with a comprehensive data pack documenting all quality checks and specifications. 

A final inspection guarantees that every vessel is ready for shipment, meeting TMCO’s highest quality, reliability, and performance standards.
