下面是详细的说明
The following is a detailed description
1 管道丝扣连接(镀锌钢管、衬塑镀锌钢管)
Connecting 1 pipe threads (galvanized steel pipe, galvanized steel pipe with plastic lining)
1 断管：根据现场测绘草图，在选好的管材上画线，按线断管。
1 broken pipe: according to the site mapping draft, draw the line on the selected pipe, line broken pipe.
a 用砂轮锯断管，应将管材放在砂轮锯卡钳上，对准画线卡牢，进行断管。断管时压手柄用力要均匀，不要用力过猛，断管后要将管口断面的铁膜、毛刺清除干净。
A grinding wheel cutting pipe should be placed in the pipe wheel saw calipers, alignment card draw off tube firmly. When the pipe is broken, the handle of the handle should be uniform, not too hard, and the iron film and burr of the pipe section should be removed after the pipe is broken.
b 用手锯断管，应将管材固定在压力案的压力钳内，将锯条对准画线，双手推锯，锯条要保持与管的轴线垂直，推拉锯用力要均匀，锯口要锯到底，不许扭断或折断，以防管口断面变形。
B for hand broken pipe should be fixed on the pipe, pressure clamp pressure case, blade alignment line drawing, push hands saw blade to keep perpendicular to the axis of the tube, push tug force should be uniform, saw to saw the end, do not wring or break, to prevent the pipe section deformation.
2 套丝：将断好的管材，按管径尺寸分次套制丝扣，一般以管径15-32mm者套丝2次，40-50mm者套丝3次，70mm以上者套丝3-4次为宜。
2 sets of wire: the broken well pipe, according to the pipe size sub set of threads, with diameter 15-32mm wire set 2 times, 3 times 40-50mm sets of silk, more than 70mm sets of silk 3-4 advisable.
a 用套丝机套丝，将管材夹在套丝机卡盘上，留出适当长度将卡盘夹紧，对准板套号码，上好板牙，按管径对好刻度的适当位置，紧住固定扳机，将润滑剂管对准丝头，开机推板，待丝扣套到适当长度，轻轻松开扳机。
A threading machine set will be caught in the wire, pipe threading machine chuck, set aside an appropriate length of the clamping plate alignment, set number, good die, according to the proper position of the dial diameter, tightly fixed trigger, the lubricant tube at the screw head, boot push plate, screw to be set to when the length, gently loosen the trigger.
b 用手工套丝板套丝，先松开固定扳机，将套丝板板盘退到零度，按顺序号上好板牙，把板盘对准所需刻度，拧紧固定扳机，将管材放在压力案压力钳内，留出适当长度卡紧，将套丝板轻轻套入管材，使其松紧适度，而后两手推套丝板，带上2-3扣，再站到侧面扳套丝板，用力要均匀，待丝扣即将套成时，轻轻松开扳机，开机退板，保持丝扣应有锥度。
B hand threading plate set wire, loosen the fixed trigger, will set screw plate plate to the zero order number on the good die plate at the required scale, tighten the trigger, will put pressure on the pipe pressure clamp case, set aside an appropriate length of clamping, the threading plate gently set into the pipe, the elastic moderate, then push hands threading plate, belt buckle 2-3, stand to the side pull sleeve wire plate, the force should be uniform, to be a screw, gently loosen the trigger, boot back plate, screw thread taper should be maintained.
3 配装管件：根据现场测绘草图将已套好丝扣的管材，配装管件。
3 equipped with fittings: according to the site will have a good sketch mapping thread pipe, pipe fittings.
a 配装管件时应将所需管件带入管丝扣，试试松紧度（一般用手带入3扣为宜），在丝扣处涂铅油、缠麻后带入管件，然后用管钳将管件拧紧，使丝扣外露2-3扣，去掉麻头，擦净铅油，编号放到适当位置等待调直。
A equipped with fittings should be required for fitting into the pipe threads, try the tightness (usually by hand into the 3 button is appropriate), in the thread apply lead oil, hemp after wrapping into pipe, and then tighten the threaded pipe with a pipe wrench, exposed 2-3 buckle, remove hemp head, wipe the oil into the lead, No. the appropriate place to wait for straightening.
b 根据配装管件的管径的大小选用适当的管钳
According to a B pipe diameter size appropriate pipe wrench
4.管段调直：将已装好管件的管段，在安装前进行调直。
4. pipe straightening: pipe fittings will be installed, before the installation of straightening.
a 在装好管件的管段丝扣处涂铅油，联接两段或数段，联接时不能只顾预留口方向而要照顾到管材的弯曲度，相互找正后再将预留口方向转到合适部位并保持正直。
A pipe thread fittings installed in place with lead oil, connecting two or several, is not only to take care of the reserved hole direction of pipe bending, find each other is after the direction of the mouth will be reserved to the appropriate site and maintain integrity.
b 管段联接后，调直前必须按设计图纸核对其管径、预留口方向、变径部位是否正确。
B pipe connection, it must be adjusted according to the design drawings, check the diameter of reserved opening direction, diameter changeable parts are correct.
c 管段调直要放在调管架上或调管平台上，一般两人操作为宜，一人在管段端头目测，一人在弯曲处用手锤敲打，边敲打，边观测，直至调直管段无弯曲为止，并在两管段联接点处标明印记，卸下一段或数段，再接上另一段或数段直至调完为止。
C pipe straightening should be put in the diversion pipe rack or tube platform, two general operation is appropriate, a person in the head of Guan Duanduan visual, one in bend with the hand hammer, side beat, observation, until the transfer pipe without bending, and marked the two mark on the pipe connection point at the unloading period or periods, followed by a period or periods of adjustment until the end.
d 对于管段联接点处的弯曲过死或直径较大的管道可采用烘炉或气焊加热到600-800℃（火红色）时，放在管架上将管道不停的转动，利用管道自重使其平直，或用木版垫在加热处用锤轻击调直，调直后在冷却前要不停的转动，等温度将到适当时在加热处涂抹机油。
D for pipe section at the connection point of the bending die or larger diameter pipe can be heated to 600-800 DEG C oven or gas welding (red), placed in the non-stop pipe rack pipe, the use of straight pipe weight, or by heating with wood pad in the hammer tap straightening, straightening after cooling before keep turning, such as temperature to oil painting in the heating position when appropriate.
凡是经过加热调直的丝扣，必须标号印记，卸下来重新涂铅油缠麻，再将管段对准印记拧紧。
After all the heating straightening the threads, must label mark, down to lead oil coated fiber winding pipe segment, and then tighten the alignment mark.
e 配装好阀门的管段，调直时应先将阀门盖卸下来，将阀门处垫实再敲打，以防震裂阀体。
E fitted with the valve pipe section, straightening should first remove the valve cover, the valve will be solid and then beat to the anti cracking valve body.
f 镀锌碳素钢管不允许用加热法调直。
F galvanized carbon steel pipe is not allowed to be straightened by heating method.
g 管段调直时不允许损坏管段。
G pipe segments are not allowed to damage the pipe during straightening.
