PVC The noise of the drainage pipe mainly comes from the water flow impact, pipe vibration and air flow turbulence. When the water flow falls into the pipe from a high place or encounters the elbow or three links, it will produce obvious impact sound, and the vibration of the pipe wall will also spread through the bracket and wall, magnifying the noise influence.

 the system research of the central air conditioning circulating cooling water system pharmaceutical water quality control technology, designed the selectivity to remove harmful ions (Ca 2 +, Mg2 +, Cl-), retain the base of beneficial oxygen anion for the characteristics of circulating cooling water quality control, through the productive test verified the water quality control effect, technical feasibility and process stability. The results show that the concentration ratio of circulating cooling water (the highest value of conductivity) is much higher than the dosage method, and the highest value of "calcium hardness plus total alkalinity" is 5 times of the limit of GB / T 50050-2017 of Design Code for Industrial Cycle Cooling Water Treatment, but the concentration of Ca 2 +, Mg2 + and Cl-is only 1 / 6,1 / 6 and 3 / 5 of the dosage method, and the turbidity is only 1 / 10 of the dosage method. The risk of corrosion and scaling is stable and controllable, the bacteriostatic effect is obvious, and the water saving potential is huge.

Abstract: Different kinds of iron-carbon micro-electrolytic fillers were prepared by sintering at high temperature of 700~1 000℃.

In modern water supply systems, material selection is critical to ensure efficiency, durability and safety. Among the various materials available, PVC (polyvinyl chloride) and UPVC (unplasticized polyvinyl chloride) have become popular choices, especially for ...

In plumbing and construction, PVC (polyvinyl chloride) and UPVC (unplasticized polyvinyl chloride) plastic valve fittings are widely used due to their durability, corrosion resistance and cost-effectiveness. However, a key aspect that users must consider is th...

When it comes to plumbing and construction, the choice of materials is crucial for ensuring durability and functionality. Among the various options available, PVC (Polyvinyl Chloride) and UPVC (Unplasticized Polyvinyl Chloride) have gained popularity due to th...

As winter approaches, it is essential to consider the impact of cold temperatures on PVC (Polyvinyl Chloride) and UPVC (Unplasticized Polyvinyl Chloride) plastic valve fittings. These materials are widely used in plumbing and construction due to their durabili...

The main material for PVC45 degree elbows is polyvinyl chloride (PVC), which has good corrosion resistance and low cost, and is suitable for various environments. It is mainly used in plumbing installation, especially in situations where the direction of the pipeline needs to be changed, such as the connection between the main pipeline and the branch pipeline.

When it comes to designing and installing a siphon system, the choice of materials and components plays a crucial role in ensuring efficiency, durability, and cost-effectiveness. PVC (Polyvinyl Chloride), UPVC (Unplasticized Polyvinyl Chloride), and plastic va...

A siphon drainage system is an efficient method for moving water from one location to another, usually from a higher elevation to a lower elevation, using the principles of atmospheric pressure and gravity. The system is used in a wide variety of applications ...
