Bronze Flange

Bronze flange is a type of pipe fitting that is used to connect pipes, valves, pumps, and other equipment to form a pipeline system. It is made of bronze, which is a copper alloy that contains around 88% copper and 12% tin. Bronze flanges are widely used in various industries, including oil and gas, chemical, water treatment, and marine applications. Bronze flanges come in various shapes and sizes, including slip-on, weld-neck, threaded, socket weld, and blind flanges. Slip-on flanges are the most common type and are easy to install. They slide over the pipe and are welded in place. Weld-neck flanges are designed for high-pressure applications and have a long neck that is welded to the pipe. Threaded flanges are used with pipes that have external threads, while socket weld flanges are used with pipes that have internal sockets. Blind flanges are used to close the end of a pipe or valve. Bronze flanges are preferred over other materials because of their excellent corrosion resistance, high strength, and durability. Bronze is resistant to corrosion from seawater, acids, and alkalis, making it ideal for marine applications. It is also resistant to wear and tear, making it long-lasting and durable. Bronze flanges are manufactured using different methods, including sand casting, investment casting, and forging. Sand casting is the most common method used to produce bronze flanges. It involves pouring molten bronze into a sand mold, which is then cooled and removed. Investment casting, also known as lost-wax casting, is used to produce complex shapes and high-quality finishes. It involves creating a wax model of the flange, which is then coated wi

Copper air chamber

Copper air chambers are devices used in plumbing systems to prevent water hammer, which is the banging or rattling sound that occurs when a faucet is turned off abruptly. The copper air chamber is a vertical pipe that is installed near the shut-off valve of a plumbing fixture, such as a toilet or sink. The copper air chamber works by creating a cushion of air that absorbs the shock of the water when the valve is closed. When the valve is opened, the air is compressed and the water flows through the pipe. When the valve is closed, the compressed air expands and pushes the water back, preventing the water hammer effect. Copper is a popular material for air chambers because it is durable, corrosion-resistant, and easy to work with. Copper air chambers are typically installed in homes and commercial buildings, and are required by building codes in many areas. To install a copper air chamber, the plumber will first shut off the water supply to the plumbing fixture.

Fire sprinkler system

Fire sprinkler system A fire sprinkler system is an active fire protection method, consisting of a water supply system, providing adequate pressure and flowrate to a water distribution piping system, onto which fire sprinklers are connected. Step 1: Fire Sprinklers Detect Heat Contrary to popular belief, fire sprinklers are not trigged by smoke. It`s an easy mistake to make, since heat is carried upward with smoke from a fire. But if smoke was the trigger, simply burning your toast in the office kitchen could be enough to drench the kitchen with water from a fire sprinkler head. Fire sprinklers work because high heat triggers the sprinkler system. When a blaze ignites, the air directly above it heats rapidly. This hot air rises and spreads along the ceiling. When the air is hot enough and reaches a sprinkler head, it triggers a chain reaction. Most sprinkler heads feature a glass bulb filled with a glycerin-based liquid. This liquid expands when it comes in contact with air heated to between 135 and 165 degrees. When the liquid expands, it shatters its glass confines and the sprinkler head activates. Step 2: Fire Sprinklers Douse the Fire Each sprinkler head is attached to a pipe that

New drill bit used on the brass elbow

The brass elbow are used to change the direction of the pipelines.the professional plumbers concern the water flow .Actually, the water flow is very important The standard EN1254-1 has required minimum hole size to regulate the water flow.For examples,the 15mm fittings require minimum hole diameter not less than 11mm .Actually,the minimum hole size not only infulence the water flow,but also the water pressure. Sometimes, the hole size is too small at the back of the elbow is the reason of break. Most factories perfer to using the twist drill bit to bore the elbow.Because such twist drill bit is very easy to grind and the cost also very cheap.But because the back of the elbow is acr shape. and the end of the twist drill bit is not .So there must left some material at the back.

Sawing way of copper pipe

Sawing is one of the most versatile and widely adapted methods for cutting tubing. Each sawing application is unique, but, generally, sawing is suitable for low-volume production. A double-head cold saw usually cuts one tube at a time. In all sawing applications, the number of teeth required on the blade is based on the number of teeth that contact the tube on the maximum arc of the cut. Having too few teeth contacting the tube limits production rates and causes vibration. Having too many teeth contacting the tube causes chips to become clogged in the teeth, perhaps causing the teeth or the blade to break. In principle, cold sawing is the same as turning and milling. Metal is removed by shearing with positive rakes. The basic blade design for cold sawing is a common tooth shape. The cutting zone is cooled to minimize saw tooth softening by lubricating it with soluble oil emulsions or synthetic oil directly in the cutting zone. tag:bronze fittings,yorkshire bronze fittings,pegler bronze fittings,gunmetal fittings,end feed bronze fittings,end feed gunmetal fittings.
