There are always some carbon elements in the stainless steel head, and carbon is iron. I believe that everyone has heard a saying that it is to take advantage of the heat to melt the iron in the high temperature and eliminate its magnetism. It is often said that the solution treatment. After hot working, the […]
Detailed introduction of the reducer
Pipe reducer for connection between pipes of two different pipe diameters. According to the shape, it is divided into two types: concentric small head and eccentric reducer. The different diameter pipe material includes stainless steel reducer (alloy steel, carbon steel reducer). The calculation method of the expansion arc length of the different diameter reducer: Concentric reducers, […]
Forming process of stainless steel tee
Stainless steel tee is a chemical pipe fitting with three ports, one inlet and two outlets; or two inlets and one outlet. It has T-shaped and Y-shaped shapes, has equal diameter nozzles, and has different diameter nozzles. At the same or different pipeline collections. The main function of the stainless steel tee is to change the […]
Processing method of stainless steel elbow
In the piping system, the stainless steel elbow is a pipefitting that changes the direction of the pipe. According to the angle, there are three kinds of most commonly used 45° and 90°180°, and other abnormal angle stainless steel elbows such as 60° are also included according to engineering needs. Stainless steel elbows are made of cast […]
Development trend of stainless steel elbow
The difference between the stainless steel elbow and the carbon steel elbow is mainly due to the difference in material. The chemical composition of the elbow will keep the surface of the elbow from rusting for a long time and will not be corroded. In a piping system, an elbow is a pipe that changes the direction of the […]
Chemical composition and heat treatment of duplex stainless steel
Duplex stainless steels require good overall mechanical properties. These properties are achieved by the selection of steel with the appropriate composition and by heat treatment by quenching and high temperature tempering. In the quenched and tempered state, the dual-phase steel has low carbon content, high plasticity and toughness, but low strength; the high carbon content is […]
What is a rolled flange?
What is a rolled flange? The rolled flange is cut into slats by the middle plate, and then rolled into a round welded joint and then processed by a flattening process. The coil is made up of cold and hot coils. After processing into a circle, the water line, bolt holes, and stops are processed. This is […]
High pressure butt-welded flanges
High-pressure butt-welded flanges are suitable for pipelines with high pressure or temperature fluctuations or for high-temperature, high-pressure and low-temperature pipelines, as well as for pipelines that are expensive, flammable, and explosive. The high-pressure butt-welding flange is not easy to be deformed, has good sealing and is widely used. The nominal pressure PN is about 16 MPa. […]
Flat welding flange and butt welding flange
What is a flat welding flange? A flat welded flange is a type of flange that is joined to a vessel or pipe by a fillet weld. It is an arbitrary type of flange. According to the degree of integrity of the connection between the flange ring and the straight section, the design is checked […]
The difference between cast flange and forged flange
What is a forging flange? Forging is a process in which a metal is plastically flowed to form a desired shape. The metal does not change in volume after plastic flow by external force, and the metal always flows to the portion with the least resistance. Forged flange is the best mechanical product in flange products. […]
