Valve Insulation Covers

Valve insulation cover introduction:

The new fiberglass movable thermal insulation sleeve is a new generation of thermal insulation product. It is made of high and low temperature resistant and fireproof insulation materials. It consists of three layers: inner lining, middle insulation layer and outer protective layer. It is designed and processed according to the specific shape of the pipeline or equipment. It is the current high-end pipeline and thermal insulation material. It can be used in different temperatures, different shapes of pipes and various types of heat and cold insulation. It is especially suitable for pipe equipment that needs to be frequently disassembled, repaired and cleaned. As soon as it was launched on the market, it was valued and favored by people in the industry. Widely used in petrochemical, electric power, metallurgy, papermaking, oil fields and other industries.
The insulation and fixed-point thickness measurement parts of the valves, pipes, straight pipes, and elbows used; with the rapid development of petrochemical, electric power, petroleum, and chemical industries, energy conservation has attracted more and more widespread attention. How to properly insulate equipment accessories has become an important issue before people. This is because the heat loss of equipment and pipelines plays a decisive role in the energy consumption of the entire equipment. According to calculations, the annual heat loss of an exposed valve of DN50-300°C is equivalent to the heat generated by burning one ton of fuel oil. There are tens of thousands of valves in petrochemical equipment, and the quality of their insulation directly affects the energy consumption and economic benefits of the equipment. However, due to the increasing number of high-sulfur and high-acid oils in recent years, the corrosion problem of equipment and pipelines has become increasingly prominent. To this end, Sinopec has specially formulated the “Administrative Regulations on Strengthening the Corrosion Inspection of Refining Units” and the “Administrative Regulations on Thickness Measurement of Equipment and Pipelines for Highly Sparse and High-Acid Crude Oil Units” requiring regular thickness measurement of Shangye pipelines at fixed points. Most pipelines are in an insulated state, and fixed-point thickness measurement requires regular removal and restoration of the original insulation. This requires the development of a new insulation device that is easy to disassemble and assemble. In order to meet the needs of the above-mentioned valves, pipes, elbow insulation and fixed-point thickness measurement,

5. Main applications:
The new type of fiberglass movable insulation sleeve is currently a high-end insulation material for pipeline equipment. It is widely used in PetroChina and Sinopec’s affiliated enterprises to process high-sulfur crude oil, so that the pipelines in petrochemical equipment are in a good monitoring state and accidents caused by corrosion can be discovered in a timely manner. Hidden dangers are ensured, safe production is ensured, and safety inspection of industrial pipelines is facilitated. At present, the products have been widely used in the insulation of valves and pipelines used in petrochemical, electric power, metallurgy, papermaking, oil fields and other industries. Especially in the field of fixed-point thickness measurement of petrochemical equipment, they have played an irreplaceable role.
Due to the importance and special requirements of thermal insulation in petrochemical, electric power and other industries, the insulation equipment we design is becoming more and more perfect with the continuous improvement of scientific and technological content to meet the requirements of different industries, different pipelines and different thermal insulation conditions. It provides services for petrochemical, electric power and metallurgy. , make corresponding contributions to the “energy-saving industry” of the oil field.
