Maintenance method of elbow elbow

First, elbow bends talk 1. How to distinguish bend elbows The difference between elbow and elbow is, in essence, the difference between "head" and "tube", but there are great differences in the production process. The most basic difference is that the elbow is relatively short compared to the elbow. R=1 times to 2 times is the elbow, and the larger multiple is called the elbow. In the production process, the cold bend tube can be bent with the ready-made straight tube bender, and the...

hydraulic test for A234wp12 Steel 90deg Elbow

What is hydrostatic test? Large diameter customized pipe bends are waiting for the hydrostatic test in Haihao Group,and the test pressure is 1.5 times the maximum possible working pressure.The hydrostatic test consists of filling a piece of equipment with a fluid at test pressure,for a given period of time,to check the existence of leakages.The test is passed if the equipment bears the test pressure without any leakage. It is a common procedure to test piping equipment,like pipes,valves,and...

Introduction and installation method of stainless steel clamp pipe fittings

Sanitary stainless steel clamp fittings are designed and manufactured for applications requiring corrosion resistance and ozone resistance. The nut threads of stainless steel joints are silver plated and pre-lubricated. The smaller size of the nut thread uses a wax seal, which not only effectively eliminates the "biting" of the stainless steel thread, but also reduces the assembly tightening torque by 40%. Sanitary stainless steel clamp fittings are easy to operate and do not require...

Pipe Flanges Details of Bangdong Pipe Technology

What is a Pipe Flange? A pipe flange connects piping and components in a piping system by use of bolted connections and gaskets. Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange (RTJ Flange). This type of connection in a pipe flange allows for ease of disassembly and separation for repair and regular maintenance. Most common specification for carbon steel and stainless steel flange is ANSI B16.5 / ASME B16.5....

Carbon steel casting flange ball valve

Ball valve structure features 1. The fluid resistance is small, and the ball valve is the one with the smallest fluid resistance in all valves. Even if it is a reduced diameter ball valve, the fluid resistance is also very small. 2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate steadily and flexibly for a long time. 3, the valve seat sealing performance is good, using PTFE and other elastic materials made of seals, the structure is easy...

How to distinguish true seamless steel tube and fake seamless steel tube

15 points can be concluded that the seamless steel pipe is not a fake seamless steel pipe 1. Indiscriminate steel pipe prone to fold. Folding is a variety of fold lines formed on the surface of the steel pipe, and this defect often runs through the entire product. The reason for the folding is due to the high efficiency of the shoddy manufacturers, the large amount of reduction, the generation of ears, and the folding of the folded products. The folding products will crack after bending and the...

what is the difference between bearing and bushing

A bushing is one classification of the overall category of bearings. A bushing is a thin tube or sleeve that allows relative motion by sliding (our type), as compared to rolling. A bushing might also be called a sleeve bearing. However, the term sleeve bushing would be redundant. Thus, a bushing is a bearing, but a bearing is not necessarily a bushing type. A bearing is the general term for something that allows relative motion between two components, surfaces, etc. more details,email to...
