New Copper Tube Market

When the self-checking straight-through copper pipe fittings are used, the copper pipes are placed with O-rings of corresponding specifications on the sealing grooves in the two interfaces of the joint body, and the pipes are inserted into the two interfaces, and the special pressure card is used. Pressure. If there is a leakage phenomenon during the use process, there will be an external leakage phenomenon at the inspection hole during the pressure test, and the card is found to be missing. It can effectively avoid the failure to be discovered in time when the pressure is applied, and the problem of leakage is found in the future use. After the steam turbine condenser is shut down, close the circulating water inlet and outlet valves of a single condenser; flush the copper tube of the condenser with clean water; inject acid cleaning liquid into the water side of the condenser for immersion cleaning; neutralize with caustic soda Soak the solution; rinse the copper tube of the condenser with clean water; rinse the copper tube of the condenser with clean water; pre-film, clean and put into operation. Add the chemical to the circulating pool and replace it with a single steam turbine condenser with chemical cleaning solution. Under the premise of not corroding the copper tube, the scale inside the copper tube can be cleaned and the vacuum degree of the turbine can be improved. The utility model has the advantages of low cost, low corrosion rate, good cleaning effect and less washing time.
