25mm 以上管径用液压煨管器(或专用煨管器),煨弯处凹扁度应符合规范规定。
Use the simmering method to simmer pipes with a necessary bend according to design
requirements. Pipes that the pipe diameter is less than 20mm may adopt a palm simmer pipe machine.
Pipes that the pipe diameter is more than 25mm may use a hydraulic simmer pipe machine (or special
simmer pipe machine). The concavity at simmering bends should accord with specifications and
regulations.
(4)断管采用钢锯或无齿锯,需断切的管子尺寸准确,将管子置于压力钳口中心卡紧,断
口平齐。断口处用锉将管口内外锉光,无毛刺,管内铁屑清除干净。
Broken pipes adopt a hacksaw or a saw without teeth. The size of pipe needing to cut should be
exact. Put pipes on the center of pressure jaw, and keep fractures even. At fracture, fill the inner or outer
of pipe orifice smoothly without any burr. The scrap iron in pipe should be cleaned clearly.
(5)管子套丝采用套丝机,根据管子外径及扣距选用相应板牙,将管子用台虎钳或龙门压
架钳紧牢固,再把绞板套在管端,均匀用力,不得过猛,随套随浇冷却液。丝扣不乱且干净清晰,
管箍上好后,管口应对严,外露丝扣不应过长。(
外露丝扣不得超过 3 扣
)
The mantle fiber of pipe may adopt a mental fiber machine. Select corresponding dies according to
the outer diameter and of pipe the pitch. Clamp the pipes firmly by using a vice or planer pressing pliers.
Then cover the capstan on pipe ends. Exert evenly not too strongly, and pour the cooling fluid on it
while covering. The clasp is not in disorder and cleaned clearly. After pipes are hoped well, pipe orifices
should be aimed at accurately. And the exposed clasp should not be too long.
(6)镀锌钢管必须采用通丝管箍连接。不得采用熔焊跨接地线,应在连接处的两端用专用
接地卡固定跨接接地线,(
镀锌钢管丝扣连接也可以直接用导电膏不采用跨接
)如下图所示:
Galvanized steel pipes must adopt harness cord pipe hoops to connect. Do not adopt fusion-
welding bridge ground wires. Use the special ground card at two ends of joints to fix and bridge the
ground wires. The connection of galvanized steel pipes is shown in the following figure.

(7)严格按图纸要求敷设管线,坐标与标高准确,固定牢固。管路敷设按规范要求加装接
线盒,管箍连接处采用专用接地线卡跨接地线,线管进入盒、箱处,按设计要求预留孔、洞,待
稳住盒、箱后再进行下道工序,需加装护口处应及时加装护口。
Lay pipelines strictly according to requirements in drawing. Both coordinates and levels are
accurate and the pipelines should be fixed firmly. The pipe lay is asked to add a terminal box according
to specification requirements. The joint of pipe hoop adopts special ground wire cards to bridge the
ground wire. Spools are put into boxes. And holes and orifices are asked to pre-leave according to
design requirements. Only after boxes have been stable, carry out the next working procedure. A
protective orifice should be added in time at the position that needs to add.
