Installation and construction steps of copper pipes

Process overview The installation and construction of copper pipes should be developed before the start of the scientific process to ensure that the construction process is up to standard. Share the installation and construction steps of copper pipes commonly used in our factory. Copper pipe straightening → cutting → pipe prefabrication → pipe installation → pipe pressure test → insulation → pipe flushing → system water The installation steps of copper pipe detailed explanation Straightening of copper pipes (1). Copper channel straightening should be filled with sand, and then straightened with a straightener; sand-filled copper pipe can also be placed […]

Ramble on about welding deformation of channel bars

During welding, the high temperature molten iron shrinks during solidification, leading to the deformation of channel bars, which has been a headache for all steel structure practitioners. Therefore, when the production of general channel bars is completed, their deformation should be measured. If it exceeds the allowable tolerance range, rectification work should be done [1](Photo 1). In serious cases, even channel bars can only be scrapped. Therefore, the control of deformation, in the factory’s manufacturing quality control, occupies a very important channel bar. To control deformation, the basic principle is to reduce the internal stress, or to give enough beam, […]

Why should steel be quenched and tempered

Why should steel be quenched and tempered? Quenching and tempering treatment: the heat treatment method of high temperature tempering after quenching is called quenching and tempering treatment. High temperature tempering refers to tempering between 500-650 ℃. Quenching and tempering can greatly adjust the properties and materials of steel, with good strength, plasticity and toughness, and good comprehensive mechanical properties. Tempered sorbite was obtained after quenching and tempering. Tempered sorbite is formed by martensite during tempering. It can be distinguished only when it is magnified more than 500 – 600 times under the optical metallographic microscope. It is a composite structure […]

Pipeline connection methods of pipeline engineering

Pipeline connection is inevitable in every pipeline project, and it is also one of the most important factors that directly determine the quality of pipeline engineering. We summarized the size of various pipeline connection methods that need attention, hoping to provide you with reference and help you improve the quality of pipeline engineering. Threaded connection (1) If it is necessary to break the pipe according to the mapping sketch on site, the iron film and burr on the cross section of the pipe orifice should be cleaned after the pipe break. (2) Before installing the pipe fittings, the appearance quality of […]

How to weld air conditioning copper pipe

The refrigeration piping system in refrigeration and air conditioning generally uses non-ferrous metal materials such as copper pipe and aluminum pipe. In the process of manufacturing, installation and maintenance, pipeline welding is a key link. It not only affects the beauty, but also affects whether the system can work normally, which must be paid great attention to. What is a air conditioning copper pipe? Air conditioning copper pipe refers to the connecting copper pipe connecting the indoor unit and outdoor unit of the air conditioner. Air conditioning copper pipe has the characteristics of hard texture, not easy to corrosion, high […]

What is a sealing gasket

What is a sealing gasket? Sealing gasket is a kind of sealing spare parts used in machinery, equipment and pipelines as long as there is fluid. It uses internal and external materials to seal. The sealing gasket is made of metal or non-metal plate material through cutting, stamping or cutting. It is used for sealing connection between pipes and between parts of machinery and equipment. According to the material, it can be divided into metal sealing gasket and non-metal sealing gasket. Metal gaskets include copper gaskets, stainless steel gaskets, iron gaskets, aluminum gaskets, etc. Non metallic ones include asbestos gasket, non asbestos […]

What is a flat washer

What is a flat washer? Flat washers are usually thin parts of various shapes to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure. Many materials and structures have such components to perform various similar functions. Due to the material and process limitations of threaded fasteners, the bearing surface of fasteners such as bolts is small. Therefore, in order to reduce the compressive stress on the bearing surface and protect the surface of the connected parts, washers are used. The flat washer is basically made by stamping. The edge of one side has radian and the other side has […]
