Insulated Steel Pipe

Product Overview

Cangzhou Huishang Pipe Fittings Manufacturing Co., Ltd. manufactures high-quality Insulated Steel Pipe for heating and thermal pipeline systems. The pipe consists of a carbon steel inner pipe, a rigid polyurethane foam insulation layer and a durable outer casing, providing excellent thermal insulation and long-term protection for buried or exposed pipelines.

Technical Specifications

Our pre-insulated steel pipes are available in a wide range of inner diameters and outer casing sizes, with the steel pipe produced in accordance with national and international standards. The polyurethane foam insulation layer offers low thermal conductivity and stable performance, while the outer casing provides mechanical protection and waterproofing. Custom sizes and insulation thicknesses are available upon request.

Manufacturing & Quality

Every insulated pipe undergoes strict quality control, including steel pipe inspection, surface preparation, foam filling, casing installation and final testing. The insulation density, thickness and adhesion are carefully controlled to ensure consistent thermal performance and long service life.

Applications

Pre-insulated steel pipes are widely used in central heating networks, district heating systems, hot water supply, chemical plants, oil fields and other thermal piping projects where energy saving and reliable insulation are required.
