It is reported that the well site to which the brigade belongs is located in the northern Shaanxi Plateau, with a large temperature difference between day and night. In view of the large number of pipe networks, length and distribution of pipelines, it insists on the working goal of “not freezing one equipment, not freezing a pipeline, a valve, an instrument”, and began to organize staff and workers to carry out self-inspection of winter prevention and thermal insulation in early October. Carry out investigation and statistical summary of all equipment, pipelines and material reserves that need to be insulated in each well site, verify and deploy them well by well, gas production tree and valve, tailor-made winter prevention measures, “suit” the well site pipelines and wellhead facilities, wrap them with “electric blanket” and put on “thermal clothing” to ensure that each well site is “warm” through the winter.
Hangzhou running Center is located in Linping District, within the ring road of Taiping Community, Xingqiao Street, with a total area of about 414000 square meters. Big lawn, is very suitable for camping and picnics, retro canopy, colorful blankets, you can experience the fun of outdoor camping in a simple tent.
After washing it all, turn to the supine position, hold the head and neck with your left hand, grab the ankle and lift the baby out of the water with your right hand, place it on a large, dry towel blanket prepared in advance, wrap it up and gently dry it, and pay attention to the skin wrinkles that should be gently dipped dry.
According to the requirements of winter construction operation, the factory leads the team, and the relevant departments of Engineering, Geology, Safety and other relevant departments cooperate to carry out the special inspection of “anti-freezing and heat preservation” in winter drilling operation, with the goal of “no freezing damage to equipment and no freezing to block pipelines”. To investigate the hidden dangers of “blanket” safety operation in winter for all drilling teams under construction. Focus on the inspection of thermal insulation measures for oil, gas, waterway, well control equipment and other equipment, and require key parts to establish anti-freezing measures to implement accounts, and take targeted thermal insulation measures to ensure the smooth completion of drilling tasks in the fourth gas production plant. At present, 103 hidden problems have been found, 98 have been rectified, and 5 are under rectification. The problems found will be reviewed to form closed-loop management.
Disadvantages: it is difficult to overcome the low wind erosion resistance of the laminated structure. Because the anchors are directly exposed on the working hot surface, when the furnace temperature is higher, the requirements for the material of anchors are the same, at the same time, a large number of heat-resistant anchors are needed for the laminated refractory fiber lining, and these anchors themselves are a heat transfer conductor. in addition, the fiber felt (blanket, board) shrinks at the use temperature, which is easy to appear gaps at the butt joint, which will affect the heat preservation effect to a certain extent. Therefore, the exposed laminated refractory fiber lining structure is suitable for low temperature heat treatment furnace.
The whole March and April is the season of mulberry fruit ripening. On the grass of fishing and ploughing, the mulberry forest is full of tourists who go green and pick fruit. They or their family or three or five friends bring blankets, pick fruit and have picnics to enjoy the rare time in spring. The mulberry fruit at this time is juicy and sweet, and friends should not miss the good time to pick fruit and go for an outing.
Our blue curtain is now a real picnic blanket, accompanying the little master to many places and seeing a lot of scenery. It realized what it once wanted. And what makes it happiest is that it always brings happiness to others.
The effect of thermal insulation is good, the thermal insulation layer adopts heat-resistant fiber thermal insulation blanket, and the surface hairiness is rich and similar to down. Thermostable ℃. Easy to disassemble, easy to install, easy to clean pipeline equipment, easy to repair and maintain. It can be used repeatedly for a long service life. High strength, toughness and easy to bend bandage. Can be tailored according to the need for heat preservation parts, processing non-standard products. The product has strong adaptability and is suitable for piping equipment with different temperature ranges and different shapes. Environmentally friendly, pollution-free, free of asbestos and any other harmful substances, harmless to people and completely. The appearance of the product is beautiful and neat and the surface can be scrubbed. Work hot, prevent personnel. Indoor temperature, convenient for air conditioning cooling, comfort.
Anti-freezing, anti-corrosion, anti-mildew, no insects, etc., and can still work normally in the environment of 456 degrees Celsius, widely used in a variety of high and middle temperature furnace gasket, heat insulation, sealing, filtration, sound insulation and various steam pipeline insulation materials, acid aluminum blanket itself does not contain binder, so the heat resistance is greatly improved.
Zhengzhou steel sleeve steel prefabricated direct buried pipe overhead laying joints should be staggered with each other, the inner and outer layers should be pressed together with each other, and the gaps should be tightly caulked, and the thermal insulation material should be tied to the surface of the working pipe by using stainless steel fastening steel belt. When the pipe is heated and expanded, the insulation layer material and the working pipe are together in the steel outer protection pipe through the support. According to the medium temperature, high temperature and ultra-high temperature of the steam medium, high temperature resistant thermal insulation materials such as hydrophobic aluminum silicate blanket / fiber felt or silica aerogel nano thermal insulation felt can be selected as a layer of thermal insulation to reach the request of high temperature resistance. Summary of Steel sleeve Steel Steam directly buried Insulation Pipe I. structural characteristics of directly buried Insulation Pipe: Steel sleeve steel directly buried insulation pipe is composed of working steel pipe, heat insulated internal flow bracket, main insulation layer, air layer or vacuum layer, outer steel pipe and outer steel pipe anti-corrosion coating. The structure of the directly buried insulation pipe is equipped with
