Complete Bundle Retubing & Reverse-Engineering: When an industrial heat exchanger experiences tube wall thinning, corrosion pitting, or tubesheet bypass, replacing the entire unit is often cost-prohibitive. We offer direct-fit replacement bundle fabrication and complete on-site retubing. Sourcing premium micrometer and laser tooling, we reverse-engineer your worn-out equipment to manufacture a replacement bundle that matches your original OEM dimensions exactly.
Advanced Leak Diagnostics & Hydro-testing: Identifying exact joint leakage pathways requires strict, methodical inspection. We utilize pneumatic test rigs, high-pressure hydrostatic testing, and helium leak testing to locate microscopic pinholes and joint cracks. Welds are inspected using non-destructive testing (NDT), ensuring that repaired units are returned to your plant with certified pressure limits.
In-House Mechanical Cleaning & Descaling: Fouling and scale accumulation on the inner and outer tube walls degrade heat transfer rates and increase system backpressures. We perform chemical descaling, rotational hydro-jetting, and mechanical shell cleaning inside our facility to restore your exchanger's heat transfer coefficients back to optimal performance.
Every repair project is modeled with specific thermodynamic profiles. Below are the key engineering specifications built into our services:
We replace worn out tube bundles completely, utilizing high-precision torque-controlled expanding for maximum joint lifespan.
Our engineering desk reconstructs exact CAD drawings from damaged, physical tube bundles, ensuring a perfect slide-in fit.
Repaired units are verified with hydrostatic pressure tests up to 50 Bar, helium leak tests, and dye-penetrant inspections.
