What is Heat Exchangers / Piping Systems?

🔥 Heat Exchangers / Piping Systems represents a complete system of precision titanium components engineered for Chemical applications. Tube/plate assembly structure, tube sheet + bundle + shell, extensive drilled holes The system integrates 0 distinct component types manufactured through 3 specialized processes.

Engineering & Design Principles

Material: Grade 2 (CP-Ti) offers excellent corrosion resistance in seawater and chlorides (potential >+0.8V vs SCE) at moderate cost. Upgrade to Grade 7/12 for strong reducing acids.

Form: Seamless tube is standard for heat exchanger bundles. Mature sizes (OD 6-50mm), short lead time, controlled cost.

Standards & Material Specifications

Standards: ASTM B338 Gr2 seamless tube, Annealed, 100% hydrostatic test + eddy current (ET)

2 Material Selection Rationale

Grade 2 CP-Ti — Industrial pure Ti, general corrosion resistance

Grade 2 (CP-Ti) offers excellent corrosion resistance in seawater and chlorides (potential >+0.8V vs SCE) at moderate cost. Upgrade to Grade 7/12 for strong reducing acids.

3 Form Selection Rationale

Seamless Tube — for fluid systems, heat exchangers

Seamless tube is standard for heat exchanger bundles. Mature sizes (OD 6-50mm), short lead time, controlled cost.

4 Manufacturing Process & Services

Core Processes:

Tube sheet drillingTube end expansion / seal weldingShell and channel welding

Toll Processing Services:

Deep hole drilling (tube sheet)Automatic TIG welding (tube end)Hydrostatic testPickling & passivation

Process Pitfalls:

  • ⚠️ Ti tube-to-sheet weld requires 99.999% argon; back-purge to prevent oxidation
  • ⚠️ Tube sheet hole tolerance H8 or better for expansion joint sealing integrity

Manufacturing Process Flow

1
Shell and channel welding

Gas Tungsten Arc Welding (GTAW/TIG) for titanium uses a non-consumable tungsten electrode with argon shielding at the torch face, trailing shield, and

2
Tube end expansion / seal welding

Gas Tungsten Arc Welding (GTAW/TIG) for titanium uses a non-consumable tungsten electrode with argon shielding at the torch face, trailing shield, and

3
Tube sheet drilling

Laser drilling of titanium uses pulsed laser energy to create precise holes through percussion or trepanning methods. Hole diameters range from 0.05 m
