is made of high-functional polyether polyol combination material and polymethyl polyphenyl polyisocyanate as raw materials through chemical reaction foaming. Polyurethane insulation pipes are used in various indoor and outdoor pipes, central heating pipes, central air conditioning pipes, chemical, pharmaceutical and other industrial pipes for thermal insulation and cold insulation projects. Overview: Since the birth of polyurethane synthetic materials in the 1930s, polyurethane foam insulation pipes have been developing rapidly as an excellent thermal insulation material. Its application range is becoming more and more extensive, and it is easy to construct and energy-saving. Anti-corrosion products are widely used in various pipelines such as heating, refrigeration, oil transportation, and steam transportation. Polyurethane Insulated Pipe - Common Problems and Solutions in Construction Polyurethane Insulated Pipe is slow to rise. This phenomenon generally occurs during construction in autumn and winter or in the morning due to a sudden drop in temperature or low temperature. This can be solved by raising the ambient temperature and black material temperature. Generally, the temperature of the black material is raised to 30-60°C, and the ambient temperature is raised to 20-30°C. Polyurethane insulation pipes rise quickly. This phenomenon generally occurs during construction in spring and summer or at noon due to a sudden rise in temperature.

The black material can be cooled with cold water or placed outdoors at night to cool naturally to avoid direct sunlight.

Thick-walled spiral pipe is a steel pipe made by perforating a solid tube blank or steel ingot and rolling it into a hollow section. The basic process is piercing and rolling. Thick-walled spiral tube is the secondary addition of spiral tube with

. Cold working is an important method to obtain high-quality and high-quality pipes, including cold rolling, cold drawing, cold tension reduction and cold spinning, etc. Extruded metal spiral pipes for high alloy steel are mainly produced by extrusion. The raw material for large-diameter thick-walled spiral pipes is round tube billet: the billet is fed into the furnace for heating, and the temperature is about 1200 degrees Celsius. The fuel is hydrogen or acetylene . Temperature control in the furnace is a key issue. After the round tube is released from the furnace, it must be punched through a pressure punch. The most common punch is the tapered roller punch. After perforation, the round tube blank is successively cross-rolled, continuous rolled or extruded by three rollers. After extrusion, the pipe must be removed and calibrated. The sizing machine uses a tapered drill bit to rotate at high speed into the steel blank to drill holes to form a thick-walled spiral pipe. The inner diameter of the thick-walled spiral pipe is determined by the outer diameter length of the sizing machine drill bit.
