Overview

HWL2 (Q) - J2-30 reinforced parallel constant power electric heat tracing cable quotation price list, quality assurance, how to connect direct sales and wholesale pipeline electric heat tracing cable wiring method, Beijing Zhonghai Huaguang DWL-P explosion-proof electric heat tracing cable is generally used in places with explosion-proof, non anti-corrosion requirements, and low environmental humidity; Explosion proof heat tracing tape is a composite layer of metal shielding mesh on the outer layer of the basic type. This structure of heat tracing tape can effectively eliminate static electricity and resist external mechanical collisions, and is mainly used in places with explosion-proof requirements.

Product Details

HWL2 (Q) - J2-30 Enhanced Parallel Constant Power Electric Tracing BeltProduct Usage

Special electric heat tracing cable for antifreeze of instrument pipelines in chemical plants

All electric tracing cables for lime water, gypsum water, process water, and other gas heating pipelines in the gas vacuum chamber heating engineering system, as well as tracing insulation, anticoagulation, antifreeze, heating, and tracing cables for industrial enterprise pipelines and storage tanks.

3、 Construction of electric heating cable

（1） Design drawings

Before construction, there should be a complete design drawing, which should include the following information:

1. The line number and power supply point are represented by rectangular grids.

2. The required heating cable model and length for the circuit. (Unit: meters)

3. The required length of heating cable per meter of pipeline length (unit: meter) is the winding coefficient.

4. The length of heating cable required for each valve. (Unit: meters)

5. List of supporting materials and accessories for the heat tracing system.

6. List of accessories for temperature control system.

7. List of materials required for construction.

8. Design considering parameters and specifications of insulation materials used.

（2） Preparation work before construction

(A) Pipeline system

1. The pipeline system and equipment have been constructed.

2. The anti rust and anti-corrosion coating has dried completely.

3. The construction specifications for pipeline systems are consistent with those shown in the design drawings.
