玻璃钢管道直管平端对接糊口操作规程Glass Pipe straight flat end of butt ends meet operational procedures一、平端对接糊口操作步骤1, flat-side docking steps make ends meet （1）材料来源所用材料由安装单位按生产厂根据工况和介质条件等提供的材料清单自行采购，也可由生产厂家提供。(1) sources of material The materials used by the installation of units and plants under the conditions of working conditions and media to provide a list of materials on their own procurement, may also be provided by the manufacturer.（2）原材料准备 按工艺单上的种类和数量，准备好原材料。布和短切毡应根据产品的规格尺寸，提前裁剪好。有锁边的布应将锁边剪掉，短切毡的边口用手撕毛。以上原材料须是检测合格的方可使用。如有需要更换的材料或变动铺层，需经有关工艺员书面认可，方可变动。(2) Raw material preparation According to process a single on the type and quantity of raw materials ready. Cloth and chopped strand mat product specifications should be based on size, ahead of a good cut. A lock the lock side edge of cloth should be cut, chopped strand mat edges of mouth Shousi hair. The above raw material shall be tested and may use. If necessary, replacement materials or changes in shop floor, subject to written approval of the craft before they change.（3）切割打磨根据图纸，找出需对接的管道，并检查规格、长度、压力等级与设计要求是否相符。在需切割处用记号笔划好切割线，用装有金刚石砂轮片的角向磨光机将需胶接的部位切开，切口应平整，切割尺寸误差不大于2mm。(3) cutting polishing According to drawings, to identifying docking pipeline, and check size, length, pressure rating is consistent with the design requirements. In the need to draw a good cut at cutting line with the marker, using films with diamond wheel angle grinder will need to cut bonding site of the incision should be flat, cut size of the error is not greater than 2mm.根据对接宽度将需胶接的地方用装有软片砂轮的角向磨光机进行打磨，切口处打磨坡度大于45，并且应磨到内衬层（内衬层厚度1.5-2.5mm）。According to docking width will be glued in place with the film wheel with angle grinder for grinding, polishing incision slope greater than 45 , and should wear to the inner layer (lining layer thickness 1.5-2.5mm).（4）对接定位 按下图将找正环(或膨胀环)塞入一头对接口，涨紧后，把另一接头套在找正环上，然后将两对接头推紧合缝，对正找平，使中间的离缝尽可能地小，并用水平仪检查管线是否水平，轴心线是否在同一直线上，方向是否正确，法兰眼是否对正(如果有法兰的话)。如果口径较小(DN400以下)或无找正环，亦可直接对正。(4) docking orientation Press the map will look for positive ring (or expansion ring) squeezed one pairs of interfaces, up tight, put the cover looking for the other joints are ring, and then push the two pairs of joints tight commissure, right now leveling, so that the middle away from the slit as small as possible, and use the level of instrument checks whether the level of pipeline, whether the axis line has been in the same line, the direction is correct, whether the flange eyes are (if any flange so). If a smaller diameter (DN400 below) to find positive or no ring, or directly to the positive. （5）配胶树脂配方由生产厂家提供，在配制前，安装者应根据当时的气温条件进行凝胶试验，确定树脂与固化剂、促进剂的配比。凝胶时间以2545分钟为宜，以整个工序操作完成后3060分钟固化为好。(5) with glue Resin formulations provided by the manufacturer, in the preparation before the installers should be based on conditions at that time the temperature gel test to determine the resin and curing agent, the ratio of accelerator. Gel time is 25 45 minutes is appropriate to the whole process is complete 30 to 60 minutes after the cure is better.配制时，应先用秤称量或量杯准确量取树脂并加入促进剂（钴盐），搅拌均匀后再加入固化剂。为防止未操作完，树脂提前固化，可分多次配制。Preparation should be the first to use an accurate balance weighing or measuring cup and add the amount of resin obtained Accelerator (cobalt salt), stirring even after adding curing agent. To prevent the operation is not finished, resin curing in advance, can be divided into several preparation.注意：严禁将固化剂与促进剂直接混合，直接混合将会发生燃烧，甚至爆炸。固化剂与促进剂在运输、贮存及搬运时，也应分离开来，并通风、避光，否则也易发生火灾事故。 Note: The curing agent is strictly prohibited direct mixing with the accelerator, direct combustion of mixing will occur, or even an explosion. Curing agent and accelerator in the transport, storage and handling, we also should be kept separate and ventilated, dark, or are prone to fire incidents.（6）封口在接缝处，刷上内衬树脂，铺上表面毡，将浸好胶的长丝绕在对接的缝隙内。然后，铺放两层短切毡。这两层短切毡应铺满整个搭接面，应用毛刷和辊轮，使之浸润充分、滚压平整、无气泡和皱纹。(6) Seal At the seams, brush on the inner resin, covered with carpet surface will be a good Baptist plastic filament wrapped around the butt of the cracks. Then, laying two layers of chopped strand mats. This should be covered with two layers of chopped strand mat surface throughout the lap, application brush and roller wheels, so that infiltration full, rolling flat, no bubbles and wrinkles.（7）糊制 待封口固化后，检查封口质量，有无气泡、裂纹等缺陷，如有，则需打磨修复，用打磨机将对接面打毛，将整个对接面刷上一层胶，根据工艺单上规定的搭接宽度和铺层顺序铺放短切毡，缠绕玻璃布，每缠一层，用毛刷蘸上树脂，使之浸透，用辊轮滚压，赶尽气泡并抹平，不得留有皱纹、未浸润等不良情况。糊制时，对接口两边应平整整齐。(7) paste system To be sealed after curing, check the seal of quality, with or without air bubbles, cracks and other defects, if any, it would take polishing repair, will junction with the grinding machine to play hair, brush on the entire docking surface layer of glue, according to the provisions of a single process overlap width and stacking sequence placement chopped strand mat, glass cloth winding, each layer wrapped with a brush dipped in resin, so soaked with roller rolling in time to make bubbles and disappearing, leaving no wrinkles , no infiltration and other bad situations. Paste system, the formation of the interface on both sides should be tidy. 平端对接连接图 应强调，糊制时，不能一次铺放二层以上的铺层，每次都应用压辊滚压。对于500以上的管的对接，可以分成两次成型，但第一次成型时，两端厚度须递减，第二次成型与第一次成型须搭接，搭接宽度不得低于50mm。 It should be emphasized, paste system, it can not a placement of more than two-story shop floor, each application of pressure roller rolling. For more than 500 docking tube can be divided into two forming, but the first time when it formed at both ends of the thickness to be reduced, the second molding and shaping to be the first lap, lap width of not less than 50mm. 凝胶前，最好留有专人看管，以防流胶，流胶处，应及时补胶，胶淤积的地方，用毛刷将胶抹匀，直至凝胶。Gel before, it is best left hand guard to prevent the flow of glue, plastic flow Branch, shall promptly make up plastic, plastic silt where the plastic Mayun with brush until the gel.糊制完成必须保证工作面的整洁和防水，保证树脂的完全固化成型。保证手糊部位48小时不和水接触。Paste the system must guarantee the completion of the clean face and waterproof, ensuring complete curing resin molding. Ensure that hand lay-up area and water for 48 hours non-contact.（8）固定支墩因管道采用平端对接连接，当管线加压后，在管线两头、弯头、三通、变径、盲端等许多地方会产生不平衡的应力以及发生管线偏移等现象，如果周围的土壤对管线不能提供足够的约束力的话，极有可能造成管线的损害。所以，为了确保管线正常运行，避免上述现象的发生，必须采取措施来约束这种不平衡的应力，预防管线的损害。通常采用的方法是用水泥固定墩固定。固定的水泥墩的尺寸可根据实际情况进行设计，以能满足使用要求为准。(8) Fixed Buttress Using flat-side docking due to the pipeline connection, when the pipeline pressure after the pipe 2, elbow, tee, adjustable, blind-side and many other places will produce uneven stress, and offset phenomena such as pipelines occurred, if the surrounding soil pipeline can not provide sufficient binding then likely to lead to pipeline damage. Therefore, in order to ensure normal operation of pipelines to avoid the occurrence of these phenomena, we must take measures to restrain this imbalance of stress, prevention of pipeline damage. Commonly used method is to use cement pier fixed. The size of a fixed concrete barrier may be designed according to the actual situation in order to be able to meet the application requirements shall prevail.（9）记录 清洗工具，贴上标明规格、压力、制作时期、糊制人员、对接编号等内容的标签，记录所用的各种材料及用量。Ping-side docking connection diagram (9) record Cleaning tools, affixed marked specification, pressure, production period, the paste system, personnel, etc. label docking numbers, records of various materials used and dosage二、平端对接糊口过程中注意事项及预防措施Flat side note the process of docking a living and preventive measures 1、树脂中含苯乙烯，能对人体造成伤害。预防措施：采取必要的防毒措施，操作者必须带口罩或呼吸器。1, resin containing styrene, can harm the human body. Preventive measures: to take the necessary anti-virus measures, the operator must wear masks or respirators.2、固化剂和促进剂直接混合会发生剧烈反应。预防措施：操作现场必须配备23个灭火器，且操作者必须是经过培训合格的。2, curing agents and accelerators direct mixing of violent reaction. Preventive measures: operating on-site must be equipped with 2 3 fire extinguishers, and the operator must be trained qualified.3、玻璃钢在糊制完毕固化过程中会放热，另外为减少湿气，用喷灯烤干时，操作不当也会因造成局部过热而引发火灾。预防措施同上。3, glass fiber reinforced plastic in the paste system will heat the curing process is completed, another to reduce the moisture, with the blowtorch, when dried, improper operation will result in local overheating caused by a fire. Preventive measures Ibid.4、糊制前的抛光打磨，会产生大量粉尘，该粉尘是玻璃纤维和树脂等化工原料的混合物，接触皮肤或吸入肺中都会对人造成伤害，甚至部分人还会产生过敏反应。预防措施：采取必要的防护措施，配备保健物品及防护药品。4, pre-polishing paste the system will create a lot of dust, the dust, glass fiber and resin mixture of chemical raw materials such as contact with skin or inhaled in the lung would cause harm to people, even some people also give rise to allergic reactions. Preventive measures: to take the necessary protective measures, with health care supplies and protective drugs.5、在长管线中施工，粉尘大，再加上一些挥发物质的综合作用，会使操作者胸闷、窒息。预防措施：管口处配备风机（5kw以上）送风或排风，工人操作时，连续工作时间不能超过一小时。5, in the long pipeline construction, dust, large, plus a number of volatile substances in combination, will make the operator chest tightness, suffocation. Preventive measures: control the mouth with a fan (5kw or more) air su
