Manufacture High-Quality, Customizable Plastic Or Acrylic (PMMA) Round Bubble Level Vials At A Low Price By Aohong Co. Round level vials, also known as circular level vials, are spirit levels utilized to determine the levelness of a surface, distinguished by their circular or dome-like shape and consisting of a slightly concave surface filled with liquid and a bubble. Constructed from plastic, glass, or metal, these vials are chosen for their durability, cost-effectiveness, and precision, catering to varied applications and environments across numerous industries, such as construction and carpentry, where precise horizontal alignment is vital. Angular value The accuracy of a bubble level vial, or its angular value, pertains to the inclination of the bubble during movement. For round level vials, accuracy is defined by the bubble’s inclination as it moves 2mm from the center along any radial direction. In contrast, for elongated bubble vials, accuracy refers to the bubble’s inclination when it shifts 2mm along the axial direction.

Tubular level vials, also known as bubble or spirit levels, are used in construction and photography to ensure surface alignment Tubular level vials, also known as bubble vials or spirit levels, are essential tools used across various industries like construction, photography, and aviation to determine the horizontality or verticality of a surface. Valued for their simplicity and precision, they are crucial in applications where accuracy is paramount, providing essential functionality to ensure surfaces are perfectly level or plumb across various professional fields and applications. Basic Structure and Operation Tube Shape: They are typically in a tube shape, which is where their name derives. The tube is filled with a liquid, usually a type of alcohol, leaving a small bubble. Bubble Movement: When the vial is placed on a surface, the bubble moves within the liquid. The positioning of this bubble indicates whether the surface is level. Graduations: Some tubular vials have graduations or lines to help indicate how off-level a surface is. The spirit bubble level vials can be made from various materials like plastic, glass, or metal, each providing different durability and clarity.

Cooling tower is a device that uses the contact between air and water (directly or indirectly) to cool water. It uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere, thereby reducing the temperature inside the tower and creating cooling water that can be recycled. Brackets and tower bodies: external supports Filler: Provides large heat transfer area for water and air Cooling tank: located at the bottom of the cooling tower to receive cooling water Water collector: Recovers water droplets carried away by the air stream Air inlet: cooling tower air inlet Water spraying device: spray cooling water Fan: Supply air to the cooling tower Axial fans are used for induced draft cooling towers.

Flanges are one of the main connecting and sealing elements in other structures such as pressure vessels, pipes, mechanical equipment, valves and pumps STANDARD ANSI 150 LB,300 LB,400 LB,600 LB 900 LB, 1500 LB and 2500 LB...

It is mainly used in chemical containers, such as tubular heat exchangers, pressure vessels, boilers, condensers, central air conditioners, evaporators, seawater desalination, and plays the role of supporting fixed tubes. The metal material makes it not only has strong rigidity, but also has great heat conduction performance. The tube sheet processing begin with the lathe machining the outer circle, upper and lower surfaces, steps, positioning slot, surface milling slot，and then into the drilling process, for special requirements, some tube plates/sheets after drilling have to continue to locate the hole and milling the slot according to the required depth，that will improve the pulling force and tightness of the expansion tube

Storage tank is not filled with water, but different properties of liquid and gas, petroleum, chemicals, acid and alkali, alcohol, gas, liquid, etc., according to the actual storage medium is different, the storage tank needs to be built into different shapes, the most common two are: like a thermos cup "cylinder" and like a ball "sphere". Metal storage tank Carbon steel storage tank, stainless steel storage tank, aluminum, etc Non-metal storage tank Plastic storage tank, ceramic storage tank, fiberglass, etc Metal and non-metal composite storage tank Steel lined polyethylene, steel lined polyolefin, steel lined rubber, etc Standard

Shell And Tube Heat Exchangers are devices that transfer part of the heat from the hot fluid to the cold fluid, allowing hot water to flow through the pipe due to the temperature difference between the hot water in the pipe and the cold water in the container. Wall heat exchanger Two fluids with different temperatures flow in the space separated by the wall, and heat is exchanged between the two fluids through the heat conduction of the wall and the convection of the fluid on the wall surface. Regenerative heat exchanger Heat is transferred from high temperature fluid to low temperature fluid through the heat accumulator composed of solid material, so as to achieve the purpose of heat transfer.
