Pay attention to matters of flange large inventory, quick collection!

Flange is a metal structure used to connect pipe fittings or mechanical components. It uses a pair of parallel dish-shaped surfaces to be connected by bolts under compression to make the connection firm and durable. Its principle is very simple and can be roughly divided into the following three steps: First, the setup personnel place the flange and the pipe together to ensure that all components are on the same plane to ensure the integrity of the flange connection. Then, the installation personnel will fix the flange to the pipe by means of fixing bolts, so that a reliable connection is formed between them. After that, the installation personnel will tighten the bolts on it to ensure close contact between the dish-shaped surfaces on both sides of the flange, so that it can be firmly connected together. In order to obtain a better use effect, the following points should be observed when using the flange: 1. Before setting, the pipeline should be cleaned in advance to ensure that there is no dirt inside the pipeline when it is installed. 2. After the setting is completed, all bolts should be tightened to ensure its strength and sealing performance. 3. It should be set in a clean and dry environment to avoid moisture and damage its performance. 4. On the pipeline bayonet, high-quality screws, washers and other fasteners should be used to ensure its sealing. 5. The opposite ends of the pipeline should be maintained at a certain level.

Let's talk about the heat treatment process of the alloy tee.

The heat treatment process of the alloy tee can be divided into ordinary heat treatment (annealing, normalizing, quenching and tempering), surface heat treatment (surface quenching and chemical heat treatment) and deformation heat treatment. Annealing is a heat treatment process in which the steel is heated to the critical point A, higher or lower than the critical point A, and slowly cooled with the furnace after heat preservation to obtain a microstructure close to the equilibrium state. The purpose of the alloy tee is to make the chemical composition and microstructure of the steel uniform, refine the grain, adjust the hardness, eliminate the internal stress and work hardening, improve the forming and cutting performance of the steel, and prepare the microstructure for quenching, the annealing process can be divided into complete annealing, incomplete annealing and spheroidizing annealing, diffusion annealing, stress relief annealing and recrystallization annealing according to different heating temperatures. The annealing temperature and complete annealing are mainly used for hypoeutectoid steel. It is a heat treatment process in which the steel is heated to 20~30 above the AC temperature, and then slowly cooled after complete austenitization to obtain a nearly balanced microstructure. The purpose of alloy tee full annealing is to refine the grain, uniform tissue, eliminate internal stress, reduce hardness, improve the workability and cold plastic deformation capacity of steel, incomplete annealing is mainly used for over-co-analysis steel to obtain spherical pearlite tissue, that is, the steel heated to A to A.

Stainless steel tee is a kind of pipe with good performance and corrosion resistance

Stainless steel tee is a kind of pipe with good performance and corrosion resistance. There is a big difference between the tee and the elbow, but in the pipeline installation, the tee has also been widely used. Although the stainless steel tee has good corrosion resistance, it still needs to be paid attention to in actual storage, otherwise it is likely to have a certain impact on the quality of the tee. Stainless steel tees are divided into two types, one is T-shaped and the other is Y-shaped. These three-way applications are different, but they are very common. Do you really know the storage method of stainless steel tee, come and have a look with Xiaobian! 1. After the production and manufacture of stainless steel tee, it is necessary to carry out the sealing of the stainless steel tee and handle it carefully to prevent the tee from being corroded. 2. The surface of the stainless steel tee is passivated and wrapped with three layers of white canvas to strengthen maintenance. 3. The commonly used material for stainless steel tee is stainless steel. Although the stainless steel plate has good corrosion resistance and firmness, it is still necessary to make a battery protection plate. This battery protection plate is preferably made of a stainless steel plate or a graphite plate. 4. When transporting the stainless steel tee, please put it into the sealed box as soon as possible. The small open box needs to be covered with white canvas, and the end of the tube must be blocked with glass. 5. When storing stainless steel tee, other materials should be used as much as possible to affect

Type and specification of stainless steel tee

Nowadays, stainless steel materials are firmly believed to be everywhere in our home. Stainless steel materials have the characteristics of light texture, corrosion resistance, high distortion resistance and very strong and durable, which occupy the main position in today's market. The stainless steel pipe is also divided into several kinds, in which the stainless steel tee is one of many pipes. I don't know if you know anything about the stainless steel tee, and it doesn't matter if you don't know much about it. Let's take a look at the types and specifications of the stainless steel tee. Introduction to the 1. stainless steel tee? The stainless steel tee itself is a coupling of the pipe and its pipeline, which is mainly used when the person in charge wants to carry out branch pipes. The stainless steel tee also has the difference between equal diameter and variable diameter. Generally, the butt top of the equal diameter tee is of the same size, while the size of the supervisor of the variable diameter tee is the same, and the size of the branch pipe will be lower than that of the supervisor. The hydraulic press bulging of stainless steel tee is a molding process that uses the radial compensation of metal composite materials to expand the branch pipe. What are the types of 2. stainless steel tee? 1. Extrusion forming stainless steel tee: The general production process includes two types of hydraulic press bulging and hot pressing forming, but these two production processes are all in the condition of not destroying the metal material mechanism

Carbon steel tee has equal diameter and variable diameter difference

Carbon steel tee has equal diameter and variable diameter difference. The butt top of equal diameter tee is the same size. The main pipe of the variable diameter tee has the same size, while the branch pipe has a lower size than the main pipe. Its main features are beautiful appearance, smooth surface, corrosion resistance, corrosion, layering. At the same time, the equal diameter stainless steel tee is exquisite in forging, with smooth surface, acid and alkali resistance, effective price calculation, beautiful appearance and layering. The difference between the structure type of butt welding tee is the difference between the receiving and the three-way connection. The vertical welding tee is generally the receiving and the three-way corner connection, while the butt welding tee is the connecting of the three-way and the receiving. And the branch take-over size is lower than the supervisor take-over size. In view of the selection of pipe production and manufacturing tee, there are two kinds of processing technology generally used at this stage, each is: hydraulic press bulging and compression molding. The hydraulic press bulging of the high-pressure tee is a molding process in which the radial compensation of the metal composite material expands the branch pipe. The process is to select a four-column hydraulic press, pour liquid into the tube blank with the same aperture as the tee, and extrude the tube blank according to the two level side cylinders of the four-column hydraulic press with the same heart fitness exercise. The volume of the tube blank is reduced after being compressed, and the working pressure of the liquid in the tube blank increases with the reduction of the volume of the tube blank. The role of the small diameter tee is to change the direction of the liquid

Where is the importance of pipeline piping

Piping manufacturers believe that the pipeline of strong corrosive gas needs to use corrosion-resistant stainless steel pipe, otherwise the inner surface of the pipeline will produce corrosion spots due to corrosion, and in severe cases, large pieces of metal will peel off or even perforate, thus polluting the pure gas for transmission and distribution. In principle, the connection of large flow, high purity and high cleanliness gas transmission and distribution pipelines shall be all welded, and the structure of the pipeline shall not change during the welding process. When welding materials with excessive carbon content, the welding part is ventilated, so that the gas inside and outside the tube penetrates each other, which destroys the purity, dryness and cleanliness of the conveying gas, and all our efforts are meaningless.
