In accordance with the reporting plan, the logistics support team of Xifeng Oil production Zone 1 will reasonably distribute glass silk cloth, blankets and other materials to each central station, and make emergency reserves of materials commonly used in winter prevention and heat preservation in advance. The central stations “dress and wear hats” to the equipment and facilities as soon as they receive the materials, bandage and paint the pipelines damaged inside and outside the station and the insulation layer, so as to ensure the orderly progress of the winter prevention and heat preservation work.
1. Inner sliding: working steel pipe → anti-corrosion coating → fibrous insulation blanket / felt → powder / stomatal insulation tile → high temperature aluminum foil radiation layer → micropore / foam insulation layer → external protection steel pipe → external anti-corrosion coating. two。 External sliding: working steel pipe → anti-corrosion coating → guide sliding bearing → fibrous thermal insulation felt (or shell) → high-temperature aluminum foil anti-radiation layer → air insulation layer → external protection steel pipe → external anti-corrosion coating. Manufacturers will also provide some special use of seamless steel tubes, such as boiler seamless steel tubes, geological seamless steel tubes and so on, this professional production of pipe materials, can have a higher value in the field of industrial manufacturing. The price of seamless steel pipe varies greatly according to the material.
The non-woven heating sheet is a kind of heating blanket element in which the hot wire is pasted between two pieces of non-woven fabric. The thickness of the product is only 3 to 5mm, the area is from 10cm to the kilowatt, the working power is from watts to several hundred watts, and the highest operating temperature is 150 ℃. It has unique advantages such as lightweight, simple design and installation, safe and hygienic use, uniform surface heat transfer, long life, low price, and can be designed randomly and conveniently according to the shape of the heating surface. It is an ideal heating element for designing a variety of low-temperature surface heating applications, and is widely used in living rooms, car cushions, health care, food heating, planting and breeding, heat preservation and other fields.
Third, boarding requirements. The school implements boarding management, during the period of admission education, all students must live on campus, except under special circumstances, parents are not allowed to enter the campus to visit or accompany students. Students should obey the management of life teachers, observe discipline and learn to live independently. Only bring daily necessities (mosquito net, mat, towel quilt or blanket, water bottle, slippers, daily toiletries) when you check in. Dormitory single bed specification: 0.8m*1.9m.
Our family of three came to the Shaying River Scenic spot, and quite a lot of people came here for a picnic. We found a shady place, which is not far from the river, and there are two big trees very close to each other, where we can tie up a hammock. Mother spread out the blanket, spread the food on the mat, and the picnic began. While enjoying the beautiful scenery, while eating my own sushi, I sighed that I admired myself so much that I had such a gift for cooking that I could make such delicious sushi.
Then open the An and B two-component discharge valve. At the same time, press the automatic filling machine switch. The equipment is automatically perfused and closed; 5. Remove the sealing flange and cover the sleeve pipe about 5 minutes after the end of the perfusion foaming (according to the ambient temperature), seal the perfusion hole with a plug, and place the pipe horizontally and numbered. 6. After passing the inspection, the insulation pipe is hoisted to the finished product area, the installation of directly buried prefabricated insulation pipe, (1) aluminum silicate fiber blanket wrapped on the working steel pipe, (2) calcium silicate (tile shell) added to the aluminum silicate fiber blanket, (3) pouring polyurethane foam in the mold, and (4) after removing the mold to make FRP insulation pipe polyurethane foam on the glass steel pipe winding machine has good mechanical properties and thermal insulation properties. In general, it can withstand temperature 120 ℃ through modification or combination with other thermal insulation materials. It can withstand 180 ℃.
Cangzhou Chengshengda Pipeline Co., Ltd. wholeheartedly welcomes friends from all walks of life at home and abroad to visit and seek common development. At present, the widely used directly buried steam pipes mainly have the following three representative structural forms: working steel pipe, anti-corrosion coating, fiber insulated pipe (felt), waterproof film, air layer, steel pipe sheath, anti-corrosion coating; working steel pipe, anti-corrosion coating, fiber insulation blanket, fine porous powder insulation block, foam insulation layer (air layer), casing Steel pipe, anticorrosive coating, powdered heat insulation paste, waterproof layer (air layer) and sheath for operation. During the working period, the steel pipe with heat source (working pipe) and the outer protective pipe (which can be made up of steel pipe + anti-corrosion coating).
