                pvc纏繞管電熱所以也有資格留在這里熔】帶鏈接步驟!

                  PVC纏繞管應將連接的兩根管道的兩端對齊,並盡↘可能靠近同一軸線。當管道橢圓度較大時,兩根管道的長度和長度軸應盡量對應。使用配套機器將電熱熔帶鋪設不然在兩根管道連接的內壁上。熱熔帶材寬度方向的線應盡可等待第四波能與端子對在同一垂直面上。
                  PVC spooled pipes shall align both ends of the two pipes connected and be as close to the same axis as possible. When the pipe ovality is large, the length and length axis of the two pipes should be corresponding as much as possible. The matching machine is used to lay the electrothermal melting belt on the inner wall of the connection of the two pipes. The center line of the width direction of the hot melt strip shall be aligned with the terminal on the same vertical plane as far as possible.
                  所述PVC纏繞管與電沉淪之眼吧熱熔帶連接,所述間隙內填〒充所述仿熱熔板;打開支撐機,將電熱』熔帶撐圓,均勻你壓緊管道內壁,機器︾的所有壓片應整齊覆蓋並壓在熱熔帶上,不得遺漏。將熱熔焊低聲一吼機(電源)與電熱熔帶電加熱電路連接,並根據管道廠家提供的電流、通電時間等焊接工藝參數進行電加熱焊接。在電加熱十億就能得到一個神石焊接過程中,電流可能會有一定的連續穩定的還原過程,但不應出非常霸道現起落突變。電熱熔帶熔焊區的表面溫度應在圓周上相對均勻。如有異常情況,應詳細檢查強大接頭,並采取相應◇措施。焊接後進行自然冷卻(一般≥40min)。焊接機具在冷卻過〖程中不得移動,焊接接頭金剛斧不得受外力作用。冷卻後,即可拆卸∑ 機床。
                  The PVC winding pipe is connected with the electrothermal melting belt, and the gap is filled with the thermotropic melting plate; open the support machine, round the electrothermal melting belt, and press the inner wall of the pipe evenly, and all the laminations of the machine shall be neatly covered and pressed on the hot melting belt without omission. Connect the hot-melt welding machine (power supply) with the hot-melt electrified heating circuit, and conduct electric heating welding according to the welding process parameters such as current and power on time provided by the pipeline manufacturer. In the electric heating welding process, the current may have a certain continuous and stable reduction process, but there should be no sudden rise and fall. The surface temperature of the welding zone of the electric heating melting zone shall be relatively uniform on the circumference. In case of any abnormality, the joint shall be checked in detail and corresponding measures shall be taken. After welding, conduct natural cooling (generally ≥ 40min). The welding machines and tools shall not move during the cooling process, and the welding joints shall not be affected by external forces. After cooling, the machine tool can be removed.

                  PVC纏繞管的⊙連接方式是通過特殊的熱風擠壓焊接工具和擠壓焊條對相鄰管道進行加ㄨ熱,使聚乙烯材料熔成一個整體的劉沖光頓時一愣連接方式,屬於剛性一陣陣搖晃不停連接。由交聯材料制成※的熱收縮帶經火焰加熱,使熱收縮帶內表面ぷ與管外表面的熱熔膠粘結在一起。
                  The connection mode of PVC winding pipe is to heat the adjacent pipes with special hot air extrusion welding tool and extrusion welding rod, so that the polyethylene material can be melted into a whole connection mode, which belongs to rigid connection. The heat shrinkable tape made of cross-linked material is heated by flame, so that the inner surface of the heat shrinkable tape is bonded with the hot-melt adhesive on the outer surface of the tube.
                  夾緊(haf-sleeve)連接:套筒與管外壁之〗間的橡膠密封圈連接¤方式為剛性連接,將外套⌒ 筒的兩半用相鄰管端部的螺栓緊固。與卡箍(haf-sleeve)連接時,由於管道外壁為螺旋波紋,必須在連接管道的波紋端》填充膨脹水的橡膠ω塞。harf套管應具有防腐蝕能力和限位裝置,以確保harf套管長期使用,不能在管道外□ 壁上移動或滑動。
                  HAF sleeve connection: the rubber sealing ring between the sleeve and the outer wall of the tube is connected in a rigid way, and the two halves of the outer sleeve are fastened with bolts at the ends of adjacent tubes. When connecting with the clamp (HAF sleep), because the outer wall of the pipe is spirally corrugated, the corrugated end of the connecting pipe must be filled with rubber plug of expansion water. Harf casing shall have anti-corrosion ability and limit device to ensure that harf casing can not move or slide on the outer wall of the pipeline for a long time.
