What Are The Unique Advantages Of Spiral Pipe

The ssaw steel pipe is divided into three layers from the inside to the outside. Working steel pipe layer is generally used seamless steel pipe (gb8163-87) spiral welded pipe (gb9711-88) according to design and customer requirements. SY / t5038-92) and straight seam welded pipe (gb3092-93). After the surface of the steel pipe is treated with advanced shot blasting technology, the corrosion grade of the steel pipe can reach gb8923-1988 SA2 level, and the surface roughness can reach gb6060.5-88 standard R = 12.5 microns.

The polyurethane insulation layer is formed by injecting rigid polyurethane foam into the cavity between the steel pipe and the outer jacket by a high-pressure foaming machine. This is the so-called "tube foaming process." Its function is water-proof, heat-insulating and heat-supporting. When the medium temperature is: 50°C, 120°C, a rigid polyaminourethane foam insulation layer is used.

High-density polyethylene protective layer prefabricated black (yellow) Plastic pipe with certain wall thickness, its function is to protect the mechanical hard disk of polyurethane insulation layer from damaging the material, the second is anti-corrosion and waterproof.

Spiral tubes are used in heating (cooling) projects, and their heat sealing effect is significant. They are used directly for direct burial, which saves energy and reduces waste. It does not occupy the environment and beautify the environment. For oil and gas transportation, can meet the requirements of long-distance transportation, avoid operation and maintenance, meet the requirements of insulation and antifreeze, reduce heating equipment, special installation, and shorten the construction period.

When used in geothermal and hot spring transportation, it can meet the cooling requirements and achieve long loss. Applicable to water conservancy, mining and other fields to meet the cold, anti-freeze, anti-corrosion requirements. In addition, pipeline transportation of chemical raw materials has a wide application space. In short, polyurethane direct insulation pipe has the advantages of energy saving, antiseptic, cold and economical appearance. In addition, it has been widely used throughout the country and is well received by users.

Polyurethane insulation pipe uses polyurethane insulation characteristics: the thermal conductivity is small, the thermal conductivity of polyurethane foam is the lowest in the insulation material, so that the heat loss of the material can be minimized. Waterproof, anticorrosive, and old: Since the closed cell rate of polyurethane foam is over 92%, polyurethane foam is used as the insulating layer of the buried pipeline, which can not only play the role of thermal insulation, but also effectively prevent water, moisture, etc. The penetration of various corrosive liquids and gases prevents the propagation and development of microorganisms.
