After the polyurethane insulated steel pipe is welded, the interface shall be filled. The following is the interface processing flow.

　　一、確保管道具備焊接和表面處理的資質(zhì)。安裝前應(yīng)套管內(nèi)外及管道兩端的泥土和污垢，確保塑料粘接部位清潔。

　　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. 截取聚乙烯厚護套護套，寬(60cm)繞保溫管長度，并搭3-5cm。確定連接套與聚乙烯外套搭接尺寸，將連接套放在連接處，確保外套居中，然后安裝熱收縮帶。

　　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)熱收縮帶密封接頭,一個星期(兩端的繞組和重疊3 - 5厘米,中間熱收縮帶橫向接縫封面)去除熱收縮套管和外殼膠部分的泥土和污垢,寬度大于熱收縮帶的寬度是用酒精清潔油,并將打毛,結(jié)合部分打毛寬度大于熱收縮的寬度。

　　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.

　　有水的保稅區(qū)應(yīng)保證干燥或用干燥燈干燥。

　　The bonded area with water shall be dry or dry with a drying lamp.

　　2、安裝

　　2. Installation

　　(1)確定熱縮帶與熱縮套筒的搭接長度。

　　(1) Determine the lap length of heat shrinkable tape and heat shrinkable sleeve.

　　(2)截斷熱縮膠帶的長度。

　　(2) Cut off the length of the heat shrinkable tape.

　　(3)將熱縮膠帶一端倒角切掉50×15mm。

　　(3) Cut off the chamfer of one end of the heat shrinkable tape by 50 × 15mm.

　　(4)熱縮帶在接頭處向內(nèi)蓋，確保熱縮帶在接頭處居中。

　　(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)用小火的圈兩層熱收縮烘焙子微和大腿上,然后分別有烤腺扣搭接縫,然后用火來回均勻烘烤腺,直到完全用熱收縮帶膠沒有翹邊和泡沫,可用的過程中加熱手套或壓力輥光滑腺熱收縮帶緊密結(jié)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)壓緊壓蓋后，從熱縮帶中部開始，先烘烤與殼體重疊的一側(cè)。從底部烘烤，并遵循烘焙規(guī)則，從下到上，從內(nèi)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)調(diào)整噴槍的火焰長度，先沿熱縮帶中部均勻加熱，中間收縮后依次加熱兩端。加熱過程中，噴槍應(yīng)前后移動，以保證熱縮帶局部不過熱。

　　(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)加熱收縮時，仔細觀察熱收縮帶邊緣是否有熱熔膠溢出。

　　(8) When heating shrinkage, carefully observe whether there is hot melt adhesive overflow at the edge of the heat shrinkage belt.

　　(9)收縮完成后，再次檢查熱收縮帶和壓蓋是否有翹邊和氣泡。如有，應(yīng)及時修復和去除氣泡，確保熱收縮帶和壓蓋光滑。

　　(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，一定要把孔打開，加入黑白混合物。黑色的就是黑色的，帶紅色的就是白色的。

　　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，分別倒入黑色料、白色料/按黑白料比1:1.1快速攪拌均勻后倒入填料孔內(nèi)形成聚氨酯發(fā)泡。發(fā)泡后密封完成。注:[267條保溫管約每條(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)
