Approvals and credentials
ADNOC approved vendor
Techwin International is an approved vendor to ADNOC (Abu Dhabi National Oil Company).
Authorised SilcoTek® distributor
Techwin is the authorised SilcoTek® distributor for the Middle East and India — Silcolloy®, SilcoNert®, Dursan® and Siltride® coatings.
Hazardous-area heating cables
The heating cables in Techwin electrical traced bundles carry IECEx, ATEX and IEC hazardous-area certification.
Factory-assembled bundles
Tube, tracer, insulation and jacket are built into one bundle in our own factory in Bhiwandi, near Mumbai, and shipped ready to install.
Why Gulf plants still trace their lines
Heat tracing in the Middle East is about holding a sample or fluid at a set temperature, not about keeping out the cold.
Hot ambient does not keep a sample warm enough
Stack gas, sour gas and many process samples have dew points well above even a Gulf summer ambient. The line still has to be held above that dew point, or water condenses and takes soluble components with it.
Air-conditioned analyser shelters
Sample lines entering a cooled shelter drop in temperature over the last few metres. Tracing has to continue to the analyser inlet.
Cold nights and winter
Desert and inland sites can see large day–night swings and winter lows that thicken heavy liquids, sulphur and fuel oil in untraced lines.
Sun, sand and UV
Outdoor runs need a UV-resistant outer jacket and sealed ends. Techwin bundles use FR-PVC, TPE, TPU or PA jackets selected for the site conditions.
Bundles for gas processing, LNG, refining and petrochemicals
Electrical heat traced tubing
Analyser sample lines and instrument impulse lines in gas processing, LNG and refining. Self-regulating cables cover about 40°C (104°F), 110°C (230°F) and 120–150°C (248–302°F); constant-wattage maintains up to 200°C (392°F); power-limiting circuits run up to 450 m (1,475 ft).
SpecificationsSteam traced tubing
Where plant steam is available: sulphur recovery, bitumen and heavy-oil service. Saturated steam up to 17 bar / 246 psi (204°C / 399°F).
SpecificationsPre-insulated tubing
Weather and sun protection for lines that need insulation but no active heating.
SpecificationsSilcoTek® coated tubing
SilcoNert® inert coatings stop sulphur compounds such as H₂S and mercaptans adsorbing on the tube wall — the key problem when sampling sour gas for trace analysis.

What to send with a Middle East enquiry
- Project, end user and applicable company specification (e.g. ADNOC)
- Sample or process fluid, and the temperature it must be held at
- Minimum and maximum site ambient, and whether the run is in direct sun
- Line length and number, size and material of tubes
- Heat source on site — power or steam
- Hazardous-area classification along the route
Frequently asked questions
Is Techwin an ADNOC approved vendor?
Yes. Techwin International, the Indian manufacturer of heat traced and pre-insulated tubing bundles, is an ADNOC approved vendor.
Who is the SilcoTek distributor for the Middle East?
Techwin International is the authorised SilcoTek® distributor for the Middle East and India, supplying Silcolloy®, SilcoNert®, Dursan® and Siltride® coated tubing, fittings and components. SilcoTek lists Techwin on its own website.
Why do sample lines need heat tracing in a hot climate?
Because what matters is the sample dew point, not the weather. Many gas samples have dew points above the highest ambient temperature, and lines cool where they enter air-conditioned analyser shelters or at night. Without tracing, water condenses in the line and the analyser under-reads.
Can Techwin heat traced bundles be used in hazardous areas in the Gulf?
The heating cables used in Techwin electrical traced bundles carry IECEx, ATEX and IEC hazardous-area certification. Give the zone classification and gas group when you ask for a quote so the right cable is selected.
Which countries in the Middle East does Techwin supply?
