Coated Tubes

Industry standard tubing coated with PVC outer jacket that provides increased protection against galvanic and atmospheric corrosion as well as additionally provides the cushioning against wear and tear of the tubes.

Overview

Techwin International offers coated tubing fabricated explicitly for use in highly corrosive environments. These tubes are industry-standard and are enveloped in a PVC outer jacket that significantly enhances protection against both galvanic and atmospheric corrosion. The additional cushioning the jacket provides also protects against the wear and tear typically seen in harsh conditions, such as maritime settings. An extruded outer jacket is applied to prevent moisture and salt ingress, which can lead to significant corrosion, with customization options available to meet your specific requirements.

Advantages

Installation of our coated tubing is similar to that of an electrical cable, which reduces costs and maximizes space.
Our coated tubes are available in long lengths, reducing material wastage and potential leakages due to fewer connections.
Our tubes boast improved roundness and flexibility, offering equal bending radii in every direction.
The extruded outer jacket protects our coated tubing from mechanical wear, abrasion, and corrosion.

Types

1. Electrical traced tubing with constant wattage heating cable

Techwin International’s Electrical Traced Tubing with Constant Wattage Heating Cable is engineered to sustain temperatures up to 200°C, with a maximum exposure limit of 260°C. Their key benefits are:

Precision-cut lengths to meet specific requirements,
Consistent power output
There’s no need for circuit breaker oversizing as there’s no inrush current at startup.

2. Electrical heat traced tubing with Self regulating heating cable:-

The Self-Regulating Heating Cable option maintains temperatures up to 121°C and withstands exposure up to 250°C. Their key benefits are:

Automatically adjusts power output in response to temperature changes,
Significantly reducing the risk of overheating.
Cut to length for your precise needs.

Keynotes

Rating & Performance

Our Electrical Traced Tubing is designed to meet the highest industrial performance standards. The rating encompasses a dual focus on safety and functionality, ensuring that even under the stress of continuous operation, the system performs with exceptional reliability.

Insulation

Our standard non-hygroscopic fiberglass insulation effectively prevents moisture ingress and thermal loss. For extreme conditions, where temperatures soar above 400°C, aerogel insulation offers superior thermal protection without compromising performance.

Outer FR-PVC Jacket

Techwin utilizes a UV-resistant FR-PVC jacket for our coated tubing, which is essential in combating corrosive atmospheres and protecting against various substances, including water, oils, acids, alkalis, and other chemicals. Our tubes can endure a temperature range of -40 to 105°C, with a safe surface temperature limit of 80°C. This outer jacket material can also be tailored to meet your specific needs.
