聚氨酯保温钢管焊接之后接口接口处理流程

来源:http://www.sdhpgy.com 日期:2020-06-09 发布人:haipo
  聚氨酯保温钢管焊接完成后,应对接口进行填充。以下是界面处理流程。
  After the polyurethane insulated steel pipe is welded, the interface shall be filled. The following is the interface processing flow.
  一、确保管道具备焊接和表面处理的资质。安装前应清除套管内外及管道两端的泥土和污垢,确保塑料粘接部位清洁。
  1、 Ensure that the pipe is qualified for welding and surface treatment. Before installation, the soil and dirt inside and outside the casing and at both ends of the pipe shall be removed to ensure that the plastic bonding parts are clean.
  2. 截取聚乙烯厚护套护套,宽(60cm)绕保温管长度,并搭3-5cm。确定连接套与聚乙烯外套搭接尺寸,将连接套放在连接处,确保外套居中,然后安装热收缩带。

  2. Cut off the polyethylene thick sheath, with a width of (60cm) of 3-5cm around the length of the insulation pipe. Determine the lap size of the joint sleeve and the polyethylene outer sleeve, place the joint sleeve at the joint, make sure the outer sleeve is in the middle, and then install the heat shrinkable tape.
  3(10厘米* 1.5毫米)热收缩带密封接头,一个星期(两端的绕组和重叠3 - 5厘米,中间热收缩带横向接缝封面)去除热收缩套管和外壳胶部分的泥土和污垢,清除宽度大于热收缩带的宽度是用酒精清洁油,并将打毛,结合部分打毛宽度大于热收缩的宽度。
  3 (10cm * 1.5mm) heat shrinkable tape seal joint, one week (winding and overlapping of both ends 3-5cm, transverse joint cover of middle heat shrinkable tape) remove the dirt and dirt on the heat shrinkable sleeve and the rubber part of the shell. The width larger than the width of the heat shrinkable tape is to clean the oil with alcohol essence, and roughen the joint part. The roughening width is larger than the width of the heat shrinkable tape.
  有水的保税区应保证干燥或用干燥灯干燥。
  The bonded area with water shall be dry or dry with a drying lamp.
  2、安装

  (1)确定热缩带与热缩套筒的搭接长度。
  (1) Determine the lap length of heat shrinkable tape and heat shrinkable sleeve.
  (2)截断热缩胶带的长度。
  (2) Cut off the length of the heat shrinkable tape.
  (3)将热缩胶带一端倒角切掉50×15mm。
  (3) Cut off the chamfer of one end of the heat shrinkable tape by 50 × 15mm.
  (4)热缩带在接头处向内盖,确保热缩带在接头处居中。
  (4) The heat shrinkable tape shall be covered inward at the joint to ensure that the heat shrinkable tape is centered at the joint.
  (5)用小火的圈两层热收缩烘焙子微和大腿上,然后分别有烤腺扣搭接缝,然后用火来回均匀烘烤腺,直到完全用热收缩带胶没有翘边和泡沫,可用的过程中加热手套或压力辊光滑腺热收缩带紧密结合。
  (5) use the first round two layers of the small heat to shrink the roast and the thigh on the top of the thigh. Then the roast glands are buckled on the joint and then evenly roasted through the fire until the whole heat shrinkable tape is used without the edge and foam. The heating gloves or the pressure roller smooth gland heat shrinkable band can be tightly combined during the heating process.
  (6)压紧压盖后,从热缩带中部开始,先烘烤与壳体重叠的一侧。从底部烘烤,并遵循烘焙规则,从下到上,从内到外,以避免泡沫。
  (6) After pressing the gland, bake the overlapped side of the shell from the middle of the heat shrinkable belt. Bake from the bottom and follow the baking rules, from bottom to top, from inside to outside, so as to avoid froth.
  (7)调整喷枪的火焰长度,先沿热缩带中部均匀加热,中间收缩后依次加热两端。加热过程中,喷枪应前后移动,以保证热缩带局部不过热。
  (7) Adjust the flame length of the spray gun, heat uniformly along the middle of the heat shrinkable zone, and heat both ends successively after the middle shrinkable. In the process of heating, the spray gun shall move back and forth to ensure that the heat shrinkable belt is not hot locally.
  (8)加热收缩时,仔细观察热收缩带边缘是否有热熔胶溢出。
  (8) When heating shrinkage, carefully observe whether there is hot melt adhesive overflow at the edge of the heat shrinkage belt.
  (9)收缩完成后,再次检查热收缩带和压盖是否有翘边和气泡。如有,应及时修复和去除气泡,确保热收缩带和压盖光滑。
  (9) After shrinkage, check the heat shrinkable belt and gland again for warping and bubbles. If any, repair and remove bubbles in time to ensure that the heat shrinkable belt and gland are smooth.
  4. 皮箱密封后,一定要把孔打开,加入黑白混合物。黑色的就是黑色的,带红色的就是白色的。
  4. After the trunk is sealed, make sure to open the hole and add black and white mixture. Black is black, red is white.
  5. 取容器,分别倒入黑色料、白色料/按黑白料比1:1.1快速搅拌均匀后倒入填料孔内形成聚氨酯发泡。发泡后密封完成。注:[267条保温管约每条(黑白混合0.6kg)]
  5. Take the container and pour the black material, white material / black-and-white material ratio of 1:1.1 into the filler hole to form polyurethane foam. Sealing is completed after foaming. Note: About 267 heat preservation pipes (black and white mixing 0.6kg)
