燕趙新聞網(wǎng)今日報(bào)道：每一位員工都要視責(zé)任如泰山，視產(chǎn)品在手中，質(zhì)量在心中，細(xì)節(jié)在精益求精中，真誠在每一道工序中，讓質(zhì)量是企業(yè)的生命這一觀點(diǎn)用腦、用心溶入到我們的工作中去，讓我們加工的工件精益完美，讓時間磨損不了優(yōu)良的質(zhì)量，讓企業(yè)因?yàn)橘|(zhì)量在可持續(xù)發(fā)展的道路上充滿生命和活力。質(zhì)量控制，環(huán)環(huán)相扣，每個細(xì)微環(huán)節(jié)都需要員工認(rèn)真敬業(yè)的工作,稍有不甚,就會造成質(zhì)量隱患。所以說，質(zhì)量就是一個準(zhǔn)則，質(zhì)量就是一個忠誠，質(zhì)量就是一個責(zé)任，質(zhì)量就是企業(yè)的生命！一個企業(yè)沒有了質(zhì)量，沒有了誠信。

Every employee should regard responsibility as Mount Taishan, see the product in hand, quality in mind, details in excellence, sincerely in each process, let quality be the life of the enterprise, this view into our work, let us process the workpiece lean and perfect, let time wear out the excellent quality Quantity allows enterprises to be full of life and vitality on the road of sustainable development. Quality control is closely related to each other. Every minute link requires the staff to work hard and conscientiously. If there is a little bit of it, it will cause hidden quality hazards. So, quality is a criterion, quality is a loyalty, quality is a responsibility, quality is the life of enterprises! An enterprise has no quality, no integrity.

聚氨酯保溫管應(yīng)在設(shè)計(jì)和施工中特別注意以下幾個問題：1、一定要真正理解供熱管道直埋敷設(shè)方式分為有彌補(bǔ)直埋敷設(shè)及無補(bǔ)償直埋敷設(shè)兩種方式，設(shè)計(jì)和施工中。確實(shí)掌握兩種方式各自的工作原理，特點(diǎn)及其應(yīng)用場所，以便在設(shè)計(jì)上合理選用，施工上安全、可靠、經(jīng)濟(jì)。2、進(jìn)場后認(rèn)真進(jìn)行檢驗(yàn)，施工前必需對生產(chǎn)的廠家進(jìn)行調(diào)研。對不合格的保溫管拒絕使用。3、聚氨酯保溫管焊接是一項(xiàng)保證工程質(zhì)量的關(guān)鍵工作，在管道施工中。4、各種井室的施工質(zhì)量直接影響工程質(zhì)量和管道的使用壽命。如井室防水不好，將使部件因浸水遭到破壞。因此，應(yīng)認(rèn)真施工，確保施工質(zhì)量5、滿足打壓條件下，必需重視管道的打壓。首先進(jìn)行灌水排凈空氣，然后分兩步做：穩(wěn)壓10分內(nèi)無滲漏。強(qiáng)度試驗(yàn)：把管道內(nèi)的壓力升至作壓力的1．5倍后；用1kg小錘在焊縫周圍對焊縫逐個進(jìn)行敲打檢查，嚴(yán)密性試驗(yàn)：把管內(nèi)的壓力降至工作壓力時，30分鐘無滲漏且壓力降不超過0．2個大氣壓即為合格；應(yīng)按規(guī)范要求做好試壓記錄。6、因保溫管埋于地下，工程驗(yàn)收。絕大部分屬于隱蔽工程，如果竣工驗(yàn)收不認(rèn)真，竣工資料不詳細(xì)，將會影響以后的使7、接頭，回填土應(yīng)在管道試壓�？⒐ふ闪浚鍜咄戤吅蠓娇蛇M(jìn)行，且必需按聚氨酯保溫管施工特點(diǎn)回填規(guī)定厚度砂子，千萬不可偷工減料。8、必需引起足夠重視�，F(xiàn)場接頭保溫須在試壓合格后方可進(jìn)行，現(xiàn)場接頭保溫施工。這一項(xiàng)內(nèi)容是聚氨酯保溫管道施工特有的，施工質(zhì)量好壞直接影響使用壽命。保溫層有現(xiàn)場發(fā)泡施工和保溫瓦施工兩種方法，不論采用哪種方法施工，都不能出現(xiàn)環(huán)形空間，開裂、脫層等缺陷，維護(hù)層的做法有多種(如高密度聚乙烯和玻璃鋼保護(hù)層)但都必須保證接頭的整體性，嚴(yán)密性，防水性。

Polyurethane insulation pipe should pay special attention to the following problems in the design and construction: 1. Must really understand the direct buried heat supply pipeline laying method is divided into two kinds of compensation for direct buried laying and no compensation for direct buried laying, design and construction. The working principle, characteristics and application sites of the two methods should be mastered in order to select them reasonably in design and to be safe, reliable and economical in construction. 2, after entering the field for careful inspection, construction must be conducted before the production of manufacturers. Refuse to use unqualified insulation pipes. 3, polyurethane insulation pipe welding is a key work to ensure the quality of the project, in pipeline construction. 4, the construction quality of various well chambers directly affects the quality of the project and the service life of the pipeline. If the well chamber is not well waterproofing, the components will be damaged by immersion. Therefore, serious construction should be carried out to ensure the construction quality 5, meet the pressure conditions, it is necessary to pay attention to pipeline pressure. First, the air is drained and then divided into two steps: steady pressure and no leakage within 10 minutes. Strength test: after the pressure in the pipeline is increased to 1.5 times of the pressure, the weld is knocked around the weld with a 1 kg hammer one by one. Strictness test: when the pressure in the pipeline is reduced to the working pressure, there is no leakage within 30 minutes and the pressure drop does not exceed 0.2 atmospheric pressure, it is qualified; pressure test record should be made according to the specification. . 6, because the insulation pipe buried underground, the project acceptance. Most of them belong to concealed projects. If the completion acceptance is not serious and the completion data is not detailed, it will affect the future so that 7, joints, backfill should be in the pipeline pressure test. After the completion of the survey, cleaning can be carried out, and must be in accordance with the construction characteristics of polyurethane insulation pipe backfill specified thickness of sand, must not jerry-building materials. 8, we must pay enough attention to it. The on-site joint heat preservation must be carried out after the test pressure is qualified, and the on-site joint insulation construction. This content is unique to polyurethane insulation pipeline construction, construction quality directly affects the service life. Thermal insulation layer has two methods: foaming construction on site and thermal insulation tile construction. No matter which method is used, there are no defects such as annular space, cracking, delamination and so on. There are many methods of maintenance layer (such as high density polyethylene and glass fiber reinforced plastic protective layer), but the integrity, tightness and waterproof of joint must be guaranteed.
