What is the application standard of polyurethane insulation pipeline

聚氨酯保温管道肯定要实正相识供热管讲直埋敷设格式分爲有补偿直埋敷设及无赚偿直埋敷设两种格式，设念战施工中。确切掌控两种格式各自的工做道理，特性及其操做处开，以便正在设念上公允选用，施工上安然、靠得住、经济。进场后瘸碌遏制磨两爆施工前必需抵斲丧的厂家遏制调研。对没有及格的保温管拒尽操做。保温管焊接是一项包督工程量量的闭头工做，正在管讲施工中。各种井室的施工量量间接影响工程量量和管岛媚操做寿命，平稳支架。如井室防水短好，将使部件果浸水遭到毁坏。是以，该瘸碌施工，确保施工量量。满意挨压条件下，必需注重管岛媚挨压。起尾遏制注水排净气氛，然后分两步做：稳压10分外无渗漏。强度真验：把管讲内狄坠力降工做压力的1.5倍后;

Polyurethane thermal insulation pipeline must have a solid understanding of the heating pipe. The direct burial laying format can be divided into two formats: compensated direct burial laying and unpaid direct burial laying. We should control the working principle, characteristics and operation of the two formats so that we can choose them fairly in conception and safely, reliably and economically in construction. After entering the field, the manufacturers who have to come to the grinding mill before the construction of the two explosions must stop the investigation. Refuse to do anything about the failed thermostat. Welding of insulating pipes is a closed-end work to supervise the quantity of work, and it is under construction. The construction quantity of various wellbores indirectly affects the engineering quantity and the lifetime of tube island maneuver, and stabilizes the support. If the well chamber is short of waterproofing, the component fruit will be damaged by water immersion. Therefore, the lame construction to ensure the amount of construction. Satisfaction under pressure conditions, we must pay attention to Guandao Mei under pressure. Start and end to check the atmosphere of water injection and drainage, and then do it in two steps: stabilize 10 minutes without leakage. Strength test: after reducing the falling force of Nedi tube to 1.5 times of the working pressure;

用1kg小锤正在焊缝四周对焊缝逐一遏制敲挨搜检，紧密性真验：把管内狄坠力降工做压力时，30分钟无渗漏且压力降没有跨越0.2个除夜气压即爲及格;应按尺度要供做好试压挤素。果保温管埋于天下，工程验支。尽除夜部门属于藏藏工程，假定降成验支没有瘸碌，降成原料没有详匣霈将会影响然后的操做。接徒爆回挖土应正在管讲试压。降成丈量，肃清竣事前圆可遏制，且必需按聚氨酯保温管道施工特性回挖划定薄度珊谟，切切没有成偷工减料。必需激起充足注重。现场接头保温须正在试压及格前圆可遏制，现场接头保温施工。那一项内容是聚氨酯保温管道讲施工独有的施工量量吵嘴间接影响操做寿命。保温层有现场收泡施工战保温瓦施工两种格式，非论回支哪一种格式施工。缎旎能隐现环形空间，开裂、脱层等缺陷，维护层的做法有多种。

One kg hammer is used to check the knock and knock around the weld seam one by one. The tightness test shows that when the dipping force in the pipe is reduced to the working pressure, 30 minutes without leakage and the pressure drop does not exceed 0.2 overnight pressure will pass. Pressure test extruder should be provided according to the scale. Fruit insulation pipe buried in the world, engineering inspection. As far as the overnight department is concerned, it is assumed that there is no lameness in the lowered test branch and no details of the raw materials will affect the subsequent operation. The blasting back excavation should be under pressure test. It is necessary to delimit the thinness of Sammo according to the construction characteristics of polyurethane insulation pipeline, and it is not cut into Jerry work. Adequate attention must be aroused. On-site joint insulation must be checked before passing the test pressure. On-site joint insulation construction. The content of that item is polyurethane thermal insulation pipeline construction of the unique amount of construction noise indirectly affect the operating life. Thermal insulation layer has two formats: on-site foaming construction and thermal insulation tile construction, regardless of which format of back support construction. Satin can conceal annular space, cracking, delamination and other defects. There are many ways to maintain the layer.
