InsulTech Insulation Blankets and Heat Shields
InsulTech, LLC (Santa Ana, California, USA) has built custom thermal and acoustic insulation since 1994: removable fabric blankets, foil and sheet metal heat shields for engines, turbines and aerospace.
T1000, T101 and T2000 Fabric Blankets: Selection and Replacement
Removable sewn fabric insulation blankets for exhaust manifolds, turbochargers, elbows, flexes and fittings on diesel and gas engines. T1000 and T101 are rated to 1500°F, T2000 to 2100°F. Cloth options include silicone, PTFE or aluminized fiberglass, silica, aramid and basalt.
- T1000, T101: up to 1500°F
- T2000: up to 2100°F
- Hot face: stainless mesh or 321 foil
- Spring and ring, hook and loop, buckle
T3000 and T3000i Foil Heat Shields: Inspection and Replacement
Insulation is encapsulated between stainless steel or Inconel foil skins joined by AWS D17.2 class A resistance welding under Nadcap accreditation. T3000 is rated to 1500°F and T3000i to 2100°F. The shields are removable, water and chemical washable and resist vibration and flammable liquids.
- T3000: up to 1500°F
- T3000i: up to 2100°F
- AWS D17.2 class A welding
- Laser etched identification
T301 Clamshell Foil Shields: Softwrap Replacement
Integral clamshell shields of 321 stainless foil are a metal alternative to sewn fabric blankets on flexes and flanges. Operating temperature reaches 1500°F. They install and remove quickly with spring and ring attachment, are water and chemical washable and resist vibration and direct flame.
- T301: up to 1500°F
- 321 stainless foil skin
- Spring and ring attachment
- For flex and flange joints
T302 and T302i Direct Welded Shields: Inspection and Replacement
The foil skin is resistance welded to AWS D17.2 class A directly onto the metal substrate and fully encapsulates the insulation where space claim is minimal. T302 is rated to 1500°F and T302i to 2100°F. The shields suit high vibration, pressure washing and chemical washing.
- T302: up to 1500°F
- T302i: up to 2100°F
- 321 stainless or A600 Inconel foil
- For piping and tubing
T4000 and T4000i Sheet Metal Cladding: Installation and Replacement
Rigid non-contact shields with a 300 series stainless shell of 16 to 22 gauge for landfill gas, methane, marine and high corrosion duty. T4000 is rated to 1500°F and T4000i to 2100°F. Attachment is by clasp, rivet or weld, and the cladding can be sealed against moisture.
- T4000: up to 1500°F
- T4000i: up to 2100°F
- 300 series stainless, 16–22 gauge
- Clasp, rivet or weld attachment
T7000, T7500 Aerospace Blankets and AS1895 Covers: Selection
Insulation for bleed air ducting, APUs and environmental control systems: T7000 foil blankets in 321 stainless or A600 Inconel, T7000 direct welded shields and T7500 fabric blankets. T7500 is rated to 1500°F and T7500i to 2100°F. AS1895 coupling covers are rigid or flexible with Min-K insulation.
- T7500: up to 1500°F
- T7500i: up to 2100°F
- 321 stainless or A600 Inconel foil
- AS1895 coupling covers
Selecting InsulTech Insulation
The insulation type follows temperature, vibration and mounting location: T1000 and T101 sewn blankets are rated to 1500°F and T2000 to 2100°F; T3000 foil and T301 clamshell shields suit washing and flammable liquids, T302 direct welded shields minimal space claim and high vibration, and T4000 sheet metal cladding corrosive and marine duty.
Aerospace programs use T7000 foil and direct welded shields, T7500 fabric blankets and AS1895 coupling covers. Parts are built to drawing, field measurement or a 3D scan of the assembly; the manufacturer runs thermal analysis and prototyping.
Materials and Attachment
Cloths include silicone, PTFE or aluminized fiberglass, silica, aramid and basalt; insulators include alkaline earth silicate, e-glass, silica and Min-K microporous; hot faces are stainless mesh, 321 stainless foil or A600 Inconel foil.
Attachment is by spring and ring, hook and loop, buckle, tie wire, custom wire forms, clasp, rivet or weld. NEC Class 1 Div 1/2 and ATEX Zone 1/2 versions are available.
