Flange connection way: It is to put two pipes, fittings or equipment, first fixed on a flange, between the two flanges, plus a flange pad, bolt together, to complete the connection. Some fittings and equipment have their own flange, also belong to the flange connection. Flange sub-threaded connection (silk) flange and welding flange. Low pressure small diameter wire flange, high pressure and low pressure large diameter welding flange are used, the pressure of the flange thickness and connecting bolt diameter and the number is different. Depending on the pressure level, the flange mats also have different materials, from low pressure asbestos mats, high pressure asbestos mats to metal mats. Flange connection easy to use, able to withstand greater pressure. In industrial pipe, flange connection is widely used. In the family, the pipe diameter is small, but also low pressure, can not see the flange connection. If in a boiler room or production site, there are flanged pipes and equipment everywhere. The main functions are as follows: 1, connecting the pipeline and maintaining the sealing performance of the pipeline; 2, facilitating the replacement of certain pipeline; 3, facilitating the inspection of the pipeline; 4, facilitating the closing of certain pipeline.
Solar Parking Lot Light
Solar parking lot lighting is an efficient means to provide lighting without the need for standard utility power. It provides cost savings by eliminating the need to trench standard electric wires for installation and providing no electric bill for life. Commercial solar lights for parking lots have been installed in many businesses and the parking lots and provide security, sustainability, and an overall green image. It uses aluminum alloy, polycrystalline solar panel, led, motion sensor, and rechargeable lithium-ion battery pack composition. We have designed and developed solar parking lamps with good waterproof performance stability.
