2. 施工工艺：Construction technique:

根据现场各种管线布置情况和流程顺序确定工艺流程，本工程采用如下工艺流程：施工准备→材料进货检验→PPR管预制加工→支吊架制作安装→PPR管安装→PPR管试验According to the arrangement and flow order of field all kinds of pipelines, confirm the process flow. This engineering adopts the following process flow: construction preparation→material stocking test→PPR pipe pre-processing→manufacture and installation of support and hanger→installation of PPR pipe→PPR pipe test

1). 施工准备：Construction preparation

施工工作及技术人员认真熟悉原图纸，领会设计意图，对图纸中和实际管道布置清楚后，才能施工。

Construction work and technicians are strictly familiar with the original drawing, comprehend design purpose, and carry out the construction after the clarity to drawing and actual pipeline arrangement.

施工人员须熟悉PPR管的一般性能，掌握必须的操作要点。在各项预制加工项目开始前，根据实际编制材料计划，将需要的材料、设备等按规格、型号准备好，运至现场。Constructer must know well the general performance of PPR, master necessary operation points,Before each precast processing project, according to the plan of practical scheduling material, well prepare the needed material and equipment according to specification and model and transport to the field.

材料设备要求：到现场的管材、管件等提供的管材和管件应符合设计规定，并附有产品说明书和质量合格证书，须认真检查并经业主验明材质，核对质保书，规格、型号等，合格后方能入库，并分别作好标识。

Material equipment requirements: The offered field pipe and pipe fittings should accord

with design prescription, adding with product stipulation and quality certification. Strictly examine and identify material by owner, check quality guarantee, specification and models etc, warehouse after qualification, and mark separately.

管材和管件的内外壁应光滑平整，无气泡、裂纹、脱皮和明显的痕纹、凹陷，色泽应基本一致。不得使用有损坏迹象的材料。如发现管道质量有异常，应在使用前进行复检。

The internal and external surface of pipe and pipe fittings should be smooth and flat, without air bladder, crack, desquamate, obvious trace and hollow, and the color and luster should be consistent. The material with damaged mark should be forbidden. If it is discovered that there is problem in the pipeline quality, recheck it before using.

管材的端面应垂直于管材的轴线。管件应完整、无缺损、无变形。

End face of pipe should be upright to the axes of pipe. The pipe fittings should be intact, without lack and distortion.

管件和管材不应长期置于阳光下照射，为避免管子在储运时弯曲，堆放应平整。搬运管材和管件时，应小心轻放，避免油污，严禁剧烈撞击，与尖锐物触碰和抛、摔、拖。管材开口处应及时封堵，以免管道堵塞造成不必要的浪费。

Pipe fitting and pipe should not be placed in the sunshine for a long time to avoid the pipe curve in storage and transportation, and piling up them should be level. When conveying pipe and pipe fittings, they should handled with care and avoid oil stain. Strong bump, cast, throw and draw is forbidden. Pipe hatch should be immediately plugged to avoid pipe jam and unnecessary waste.

施工现场与材料存放处温差较大时，应于安装前将管件和管材在现场放置一定时间，使其温度接近施工现场环境温度。

When there is large difference in construction field and storage temperature, should place pipe fitting and pipe at the field before installation for certain time and make its temperature closure to environment temperature of construction field.

本项目PPR管道采用热熔连接，施工前应仔细检查所使用的热熔机具、割刀是否符合要求和正常使用，使用的电源及电线是否正常和安全。如下图：

This project pipe-PPR pipe adopts heat fusion. Before construction, should carefully examine whether the using hot melt equipment and cutter knife accord with requirements and normal service, the using power supply and wire are normal and security. as the
