Operation points of grooved pipe fittings: steel pipe rolling groove. Cut the pipe according to the required length with a pipe cutting machine. The incision should be smooth and the burrs should be removed, and the steel pipe should be erected on the TWG-2 grooving machine. Use a spirit level to adjust the tailstock of the grooving machine so that the grooving machine and the steel pipe are in a horizontal position, then stick the end face of the steel pipe to the end face of the grooving wheel baffle so that the angle between the steel pipe and the end face of the grooving wheel baffle is 90°, and start the grooving The motor is used to make the upper pressure wheel evenly roll the steel pipe to the set groove depth, check the groove depth and width with a vernier caliper, unload the rolling groove machine, and take out the steel pipe.

 

The installation method of the grooved joint requires the customer to refer to the relevant technical requirements. The first step is to process the groove, remove the burr, ensure that the sealing surface of the steel pipe to be installed is flat and smooth, check the rubber sealing ring, and replace it in time if it is broken. Install in the middle of the two interfaces, not in the groove; straighten the central axis of the pipeline, leave a gap at the two ports, and apply lubricant on the rubber sealing ring (the lubricant can be detergent, not oil lubricant) .Install the clamps on the outside of the rubber sealing ring, press the clamps with both hands (use a wooden hammer if necessary), and tighten the bolts evenly and alternately when installing the fasteners. The tightening torque is moderate to prevent damage to the bolts. Visually check whether the rubber sealing ring is In the clamp piece, avoid wrinkling at the two joints.

 

Steel pipe opening and installation of mechanical three-way and four-way steel pipes are first opened at the connection part with a professional hole opening machine. The size of the hole is in accordance with the hole ruler table in the product manual, and the corresponding drill bit is selected according to the diameter of the hole. Use a chain to fix the drilling L machine at the predetermined position of the steel pipe, calibrate with a level, start the motor, and turn the drill bit; operate the hand wheel to make the drill bit go down slowly, and add a proper amount of drill bit lubricant to complete the hole opening. Clean up the drilled iron filings and the residue at the hole opening, and use a grinder to grind the burr at the hole until it is smooth.
