Except for

, other work is carried out in the open air. (6) The coiling is carried out by a 4-roller coiling machine with hydraulic front and rear brackets. LSAW spiral steel pipes can be rolled into long steel plates because of the hydraulic brackets. The arc is held up without the cooperation of a crane, the gravity deformation is small, and the tiles are rolled and formed with good quality instead of rebounding. The purpose is to create greater profits for Taiwan and our people, so that the price of imported ore has no rebound power, and welding

The prefabricated direct-buried thermal insulation pipe adopts the direct-buried heating pipeline technology, which marks that the development of China’s heating pipeline technology has entered a new starting point. With the decrease of energy and the increase of demand, energy saving, emission reduction and environmental protection have become the trend of global development. Countries and places also vigorously advocate the development, application and industrialization of energy saving, emission reduction and environmental protection products.

, enhance elasticity and so on. Traditional insulation pipes are laid in trenches and overhead, which has high project cost and long construction time. However, the polyurethane insulation pipe adopts the direct buried laying method, which occupies less land, is simple and quick to construct, and is conducive to environmental protection. From these three aspects, we can already clearly see the difference between polyurethane insulation pipes and traditional insulation pipes. As time goes by, new things are created, and old things die out, traditional insulation pipes have begun to slowly.

D114*3.5 Polyurethane Rigid Foam Insulation Pipe is in stock. Polyurethane rigid foam insulation material is an important branch of the polyurethane industry. This type of product has been used in the European construction industry for 40 years since the 1960s. Some countries have also passed legislation to use polyurethane as a thermal insulation and waterproof material for the construction industry. In recent years, with the rapid development of my country’s building energy-saving market, polyurethane rigid foam insulation products have been widely used in the field of building insulation and waterproofing, and have become one of the leading thermal insulation and energy-saving products in the market.
Polyurethane rigid foam breaks the single function of traditional building materials – waterproof is not thermal insulation, thermal insulation is not waterproof, and once the waterproof layer leaks, the thermal insulation layer will lose its thermal insulation function. Compared with other single-function thermal insulation or waterproof materials, polyurethane rigid foam has obvious advantages: polyurethane rigid foam has a multi-purpose function, and has many functions such as thermal insulation, waterproof, sound insulation, and vibration absorption.
Consists of four parts. (1) Working steel pipe: According to the technical requirements of the conveying medium, seamed steel pipe, seamless steel pipe and double-sided submerged arc spiral welded steel pipe are respectively used. (2) Insulation layer: use rigid polyurethane foam. (3) Protective shell: high-density polyethylene or fiberglass. (4) Leakage alarm line: When manufacturing high-temperature prefabricated direct-buried insulation pipes, an alarm line is buried in the insulation layer close to the steel pipe. Once leakage occurs somewhere in the pipeline, it will pass through the conduction of the alarm line.

Polyurethane direct-buried insulation pipes replace the original insulation settings, on the one hand, to better reflect sustainability in development, and on the other hand, to adapt to rapid development. Next, let’s introduce the direct buried insulation pipe. The direct buried insulation pipe can be divided into two different types. The type is a kind of insulation layer that uses improved urea foam ester hard as the insulation pipe. It does not pollute the surrounding environment, has a long service life, and has stable properties. Now this feature is not only developed and applied to polyurethane direct-buried thermal insulation pipes, but also a type of prefabricated direct-buried thermal insulation pipes. This is a piece of development for the thermal insulation pipe market. Xintiandi. Polyurethane direct buried insulation pipe uses composite insulation material as the insulation layer of the insulation pipe. The main structural layer is between the insulation layer close to the steel pipe and the polyethylene outer casing, thus forming a polyurethane foam insulation layer with good insulation performance. composite layer. Moreover, the above two types of direct-buried thermal insulation pipes are convenient for construction, energy-saving and material-saving, and have strong wear and corrosion resistance. In addition, this type of directly buried thermal insulation pipe has a wide range of applications, and the ground excavation area is small. Polyurethane direct-buried thermal insulation pipes are used in heating (cooling) projects, and their thermal insulation and sealing effects are remarkable. They are used for buried laying, which not only saves energy, reduces waste, does not occupy land, but also beautifies the environment. When used in oil and gas transportation, it can meet the requirements of long-distance transportation, avoid operation and maintenance, meet the requirements of heat preservation and antifreeze to a large extent, reduce heating equipment, and the installation is particularly convenient, shortening the construction period.
