Spiral steel pipe is a type of pipeline used for transporting high-temperature hot water, usually manufactured using spiral welding technology. It is widely used in residential heating, hot water and steam transportation, oil and gas pipelines and other fields. It is often seen in urban centralized heating pipelines, oil transportation pipelines, water transmission pipelines in high-altitude areas, and industrial pipeline projects in production areas.

Definition and purpose
Spiral steel pipe is a type of pipeline used for transporting high-temperature hot water, usually manufactured using spiral welding technology. It is widely used in residential heating, hot water and steam transportation, oil and gas pipelines and other fields. It is often seen in urban centralized heating pipelines, oil transportation pipelines, water transmission pipelines in high-altitude areas, and industrial pipeline projects in production areas.
Product characteristics
thermal insulating property
Taking polyurethane directly buried insulation pipe as an example, it is divided into three layers from the inside to the outside. The second layer is polyurethane insulation layer, which is made by injecting hard polyurethane foam solution into the cavity between the steel pipe and the outer protective layer at one time by the high-pressure foaming machine. This structure reduces heat loss by more than 40% compared to ordinary pipelines, making it the insulation material with low thermal conductivity (≤ 0.024) and high thermal resistance among all building materials in China. Its thermal conductivity is only half of that of EPS foam polystyrene board, which can effectively reduce heat loss.
Corrosion Resistance
The anti-corrosion and insulation steel pipes used in the transportation of natural gas and other processes comply with the standard SY/T0413-2002 DIN30670, which can ensure that the pipelines are not corroded or damaged. Some anti-corrosion spiral steel pipes, such as epoxy coal tar anti-corrosion steel pipes for drainage and 3PE anti-corrosion pipes, also have good anti-corrosion capabilities and can extend the service life of pipelines.
