铜管的机械连接应采用与管径相匹配的专用连接管件和夹紧工具

铜管机械连接

N、 0.1铜管夹紧连接应符合下列要求：

1采用DN50以下夹铜管连接；

2采用与管径相匹配的专用连接管件和夹紧工具；

三。将铜管插入管件过程中，管件内密封圈不得扭曲变形。将管子插入管件底部后，轻轻转动管子，使管子与管件的连接段保持同轴，然后夹紧；

卡箍压下时，卡钳端面应与管件轴线垂直，达到规定的卡箍压力1～2S后才能松开；

5卡接采用硬铜管。

N、铜管连接应符合下列要求：

一对直径小于DN50、需拆卸的铜管可采用卡套连接；

2应使用扳手或专用扳手连接，不得使用管钳拧紧螺母；

三。连接件应采用二次装配。在第二次装配中，应将螺母从扭矩波动点拧紧1/4圈；

4卡套连接一次完成后，应将紧固螺母从扭矩波动点旋转1~1圈，使卡套边缘切入管内，但不要过紧。

N、 0.3铜管法兰连接时，松套法兰规格应符合有关规定；垫片可采用耐温布橡胶板或铜垫片；紧固件采用镀锌螺栓对称拧紧。

N、黄铜配件和附件的螺纹连接应使用0.4聚四氟乙烯胶带。先用手拧入2-3个螺纹，然后用扳手一次拧紧。不要让他们回头。拧紧后应留2-3个螺纹尾。

The mechanical connection of copper pipe shall adopt special connecting pipe fittings and clamping tools matching with pipe diameter

Mechanical connection of copper pipe

N. 0.1 copper pipe clamping connection shall meet the following requirements:

1. Copper pipes with diameter less than DN50 can be connected by clamping;

2. Special connecting pipe fittings and clamping tools matching with pipe diameter shall be adopted;

3. In the process of inserting the copper pipe into the pipe fitting, the inner sealing ring of the pipe fitting shall not be twisted and deformed. After the pipe is inserted into the pipe fitting to the bottom, the pipe shall be slightly rotated to keep the joint section of the pipe and the pipe fitting coaxial before clamping;

When the clamp is pressed, the end face of the caliper should be perpendicular to the axis of the pipe fitting, and the caliper can be released only after it reaches the specified clamp pressure for 1 ~ 2S;

5. Hard copper pipe shall be used for clamping connection.

N. The copper pipe connection shall meet the following requirements:

A pair of copper pipes with diameter less than DN50 and to be disassembled can be connected by ferrule;

2. Spanner or special spanner should be used for connection, and pipe wrench should not be used to tighten nut;

3. The secondary assembly should be used for the connection part. In the second assembly, the nut should be tightened 1 / 4 turn from the point of torque surge;

4. When the ferrule connection is completed at one time, the tightening nut should be rotated 1 ~ 1 turn from the torque surge point to make the ferrule edge cut into the pipe, but not too tight.

N. 0.3 when the copper pipe flange is connected, the loose flange specification shall meet the relevant regulations; the gasket can be made of temperature resistant cloth rubber plate or copper gasket; the fastener shall be made of galvanized bolts and symmetrically tightened.

N. 0.4 Teflon tape should be used for threaded connection of brass fittings and accessories. Screw in 2-3 threads by hand first, and then tighten them with a spanner at one time. Do not turn them back. 2-3 thread tail shall be left after tightening.

铜管机械连接应采用专用的与管径相匹配的连接管件和卡压机具

铜管机械连接

N.0.1 铜管卡压连接应符合下列规定：

1 管径不大于DN50的铜管可采用卡压连接；

2 应采用专用的与管径相匹配的连接管件和卡压机具；

3 在铜管插入管件的过程中，管件内密封圈不得扭曲变形，管材插入管件到底后应轻轻转动管子，使管材与管件的结合段保持同轴后再卡压；

4 卡压时，卡钳端面应与管件轴线垂直，达到规定的卡压力后保持1～2s方可松开卡钳；

5 卡压连接应采用硬态铜管。

N.0.2 铜管卡套连接应符合下列规定：

1 对管径不大于DN50、需拆卸的铜管可采用卡套连接；

2 连接时应选用活动扳手或专用扳手，不宜使用管钳旋紧螺母；

3 连接部位宜采用二次装配。第二次装配时，拧紧螺母应从力矩激增点起再将螺母拧紧1/4圈；
