Din2634 Pn25 Welding Neck Flange
DIN2634 flange have two holes, can wear bolt, make the two flange tight even.Between the gasket seal.It is the connection of the two pipes, fittings or equipment, fixed on a flange, a first between the two German standard flange, and flange pad, bolt fastening together, complete the connection.According to the connection parts of flange and flange can be divided into the container.This product is mainly used in oil and gas pipeline engineering, the natural gas pipeline engineering, chemical plants, municipal engineering, sewage treatment, power plant, shipbuilding, pharmaceutical, dairy products, beer, beverage, water conservancy and other industries.DIN2634 flange will not produce corrosion, pitting, corrosion or wear and tear, play an important role and value in use, used in different industries and fields.
Butt welding flange is two large diameter pipe connection device, usually two flange and number of the bolt, its plastic strength is low, after adding suitable amount of carbon becomes hard, plastic lower strength enhanced.Connection it may need to bear very high tensile, compression, torsion and shear strength.Butt welding flange conveniently, manufacture simple, low cost, widely used, but with poor rigidity, therefore shall not be used for supply and demand, flammable, explosive and high vacuum degree requirements of the chemical process piping systems and height, extremely dangerous situations.Sealing surface type plane and surface.Butt welding flange welding electrode consumption is much, can not stand high temperature, high pressure, repeated bending and temperature fluctuations.

It is very important that the bearing is in good condition. Generally, multiple axle box temperature detectors can be arranged along the railway line, and the infrared temperature of the radiator can be measured to detect whether the temperature of the axle box rises abnormally. Although it is possible to use these high-performance devices to eliminate dangerous bearings, in the research and development of new types of bearings, in order to ensure the normal operation of the various components of bearings, lubricants, etc., it is necessary to study preventive measures. As the electric traction line grew, the grounding device was installed at the time of the engine, but new damage was found on the sliding bearing and rolling bearing of the trailer. Therefore, the release of leakage current has become a new research goal. The effect of grease and leakage current on the metal Even with grease, the leakage current will destroy the coating of the grease through the discharge, causing the electric corrosion of the shaft and the bearing. If the electric corrosion continues to develop, the probability of the temperature rise of the axle box will be Will increase.
If a leakage current occurs in the part that makes up the bearing, the current will cross the barrier formed by the lubricant, breaking the insulation and flowing along the arc. At this time, the local temperature of the bearing metal rises and the metal structure changes, resulting in a harder white half-moon martensite work progress than the parent metal. The second stage of the vehicle/orbit interaction test uses a tanker, in 1999. It was carried out online in Topeka, Kansas and Fort Madison, Iowa in August and was completed in the near future. In this test, testing vehicle response and track geometry conditions was done by running eastward while the tanker was loaded and running westward when empty. These test data will be used to develop a new tanker neural network model. The third phase of the commercial operation test plan for the coal-powered gondola was carried out in 2000.
