duct clampThe connection method, the duct clamp technology has become the technology of liquid and gas pipeline connection. Although this technology developed late in China, it was quickly accepted by the domestic market due to its advanced technology. From 1998 to now, after several years of development and application, the two traditional pipe connection methods of flange and welding have been gradually replaced. Not only the technology is relatively mature, the market has also been widely recognized, and has been actively guided by national laws and regulations.

Connection method of 1. duct clamp

1. Use a pipe cutting machine to cut the steel pipe according to the required length, and use a level to check the cutting section to ensure that the cutting section is perpendicular to the central axis of the steel pipe. If the cut has a burr, grind it flat with a grinder.

2. Clamp the steel pipe that needs to be slotted on the tailstock of the slotting machine and the slotting machine, and level it with a level to make the steel pipe in a horizontal position.

3. The section of the steel pipe processing end is closely attached to the slotting machine, so that the central axis of the steel pipe is perpendicular to the roller surface.

4, gently press. Jack, make the upper pressure wheel close to the steel pipe, start the grooving machine, and make the roller rotate for one week. At this time, pay attention to observe whether the steel pipe section is still close to the grooving machine. If not, adjust the steel pipe to level. If it has been tightened, slowly press the jack to make the upper pressure roller roll the steel pipe evenly to the predetermined groove depth.

5. When stopping the pliers, check the groove depth and groove width with vernier caliper. After confirming that the standard requirements are met, remove the jack and take out the steel pipe. In the process of the use of the fixture, to grasp the matters needing attention, and pay attention to the maintenance after use, in order to extend its service life.

Induct clampIn the process of application, it is necessary to grasp the precautions and pay attention to the maintenance after use to extend its service life. The rubber flexible joint adopts the air duct clamp instead of the flange and bolt. During installation, the two pipe ports of the rubber joint of the clamp can be respectively set on the pipe to be connected by the air duct clamp, and the rubber joint is fixed on the pipe.
