What is the application standard of polyurethane insulation pipeline

聚氨酯保溫管道肯定要實正相識供熱管講直埋敷設(shè)格式分爲有補償直埋敷設(shè)及無賺償直埋敷設(shè)兩種格式，設(shè)念戰(zhàn)施工中。確切掌控兩種格式各自的工做道理，特性及其操做處開，以便正在設(shè)念上公允選用，施工上安然、靠得住、經(jīng)濟。進場后瘸碌遏制磨兩爆施工前必需抵斲喪的廠家遏制調(diào)研。對沒有及格的保溫管拒盡操做。保溫管焊接是一項包督工程量量的閉頭工做，正在管講施工中。各種井室的施工量量間接影響工程量量和管島媚操做壽命，平穩(wěn)支架。如井室防水短好，將使部件果浸水遭到毀壞。是以，該瘸碌施工，確保施工量量。滿意挨壓條件下，必需注重管島媚挨壓。起尾遏制注水排凈氣氛，然后分兩步做：穩(wěn)壓10分外無滲漏。強度真驗：把管講內(nèi)狄墜力降工做壓力的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小錘正在焊縫四周對焊縫逐一遏制敲挨搜檢，緊密性真驗：把管內(nèi)狄墜力降工做壓力時，30分鐘無滲漏且壓力降沒有跨越0.2個除夜氣壓即爲及格;應(yīng)按尺度要供做好試壓擠素。果保溫管埋于天下，工程驗支。盡除夜部門屬于藏藏工程，假定降成驗支沒有瘸碌，降成原料沒有詳匣霈將會影響然后的操做。接徒爆回挖土應(yīng)正在管講試壓。降成丈量，肅清竣事前圓可遏制，且必需按聚氨酯保溫管道施工特性回挖劃定薄度珊謨，切切沒有成偷工減料。必需激起充足注重。現(xiàn)場接頭保溫須正在試壓及格前圓可遏制，現(xiàn)場接頭保溫施工。那一項內(nèi)容是聚氨酯保溫管道講施工獨有的施工量量吵嘴間接影響操做壽命。保溫層有現(xiàn)場收泡施工戰(zhàn)保溫瓦施工兩種格式，非論回支哪一種格式施工。緞旎能隱現(xiàn)環(huán)形空間，開裂、脫層等缺陷，維護層的做法有多種。

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.
