Hebei Xinmian Building Materials Co., Ltd. Engineering Electric Heating Blanket

Hebei Xinmian Building Materials Co., Ltd.Engineering Electric Blankets: Multi-Size Options for Tunnel/Pipeline Construction, 24-Hour Constant Temperature Control During winter construction of tunnel excavation and pipeline laying, it is necessary to heat the work surface or materials to maintain a constant temperature. However, there are significant differences in size and temperature requirements across different scenarios, making it difficult for standard fixed-size electric blankets to fit. Hebei Xinmian Building Materials Co., Ltd. offers a range of engineering electric blankets with multi-size options, supporting 24-hour constant temperature control, perfectly suited for complex construction scenarios such as tunnels and pipelines.

Multiple specifications for diverse construction needs

1. Standard Specifications: Meet Basic Requirements：

• Sizes: 1m x 2m, 1.2m x 3m, 2m x 4m, etc., power 200W/㎡-300W/㎡, suitable for small pipelines and local concrete curing.

• Features: Lightweight and portable, single-person operation, reaches the set temperature within 30 minutes of power on.

• Customizable Arc-shaped Electric Blanket for Tunnel Use (suitable for tunnel arches and side walls), width adjustable from 1-3m, length cut to order, conforms to tunnel curvature, eliminates heating dead zones.

• Pipe-Specific: Offers "Spiral Electric Heating Blankets" that fit pipes with diameters ranging from 50mm to 1000mm, featuring an adhesive outer layer for tight wrapping around the pipe surface, ensuring even heating.

• Major Project: Supports multi-mat拼接, customizable "10m×5m" and larger electric blanket sizes, equipped with zone thermostats for independent temperature control of different areas.

24-hour temperature control to ensure construction quality

1. Smart Temperature Control SystemThe electric blanket is equipped with a digital temperature controller featuring a display, allowing for a target temperature setting (5-60℃). It automatically shuts off power when the temperature reaches the set value and turns it on again when it falls below the set temperature, achieving a 24-hour unattended constant temperature control.

2. Temperature Compensation FeatureFor applications with rapid heat dissipation, such as tunnels and pipelines, an internal temperature compensation chip is integrated. It automatically boosts power (up to a temporary increase of 20%) when the ambient temperature drops suddenly, to prevent temperature fluctuations.

3. Low-power designUtilizing energy-saving heating wires, the power consumption in a constant-temperature state is 15% lower than that of conventional industrial electric heating blankets, resulting in significant long-term energy savings.

Hebei Xinmian Building Materials Co., Ltd.'s engineering electric heating mats have been serving various tunnel and pipeline projects in Hebei and Shanxi provinces, including a pipeline winter construction project. By using customized wrapped electric heating mats, the pipeline preheating temperature was stabilized at 12°C, enabling the welding operations to be completed successfully and earning high recognition from the client.
