The main difference between stainless steel elbows and other elbows a304 stainless steel elbows and carbon steel elbows is the difference in materials, and the chemical composition contained therein will keep the surface of the elbow from rusting and corrosion for a long time. In piping systems, elbows are pipe fittings that change the direction of the pipe. Depending on the angle, there are three most commonly used angles: 45° and 90°180°. In addition, it also includes other elbows, such as 60°, depending on engineering needs. In today's elbow industry, our various industrial production is inseparable from the connection of pipes. The best parts tool for pipe connections is the flange. There are many common types of elbows on the market, which may be very comprehensive. In order to meet our standardized production requirements and create convenient working and production conditions for us, today's flanges include high pressure flanges and butt welding flanges, etc. The working and production conditions required for these two types of flanges and their installation requirements are different is to be sure to pay attention to his correct way of operation to increase the use of his products. What is the difference between the head

When connecting elbows, washers, screws and nuts are required. These are necessary products for flange connections. High pressure flanges. Low pressure flanges have different requirements for generating pressure when connecting pipes. We have to choose the type of product through strict calculations and the industrial production requirements of the elbow. Butt-welding flanges absolutely require us to electro-weld and weld. This requires us to have a professional and formal method of connection. It reduces the occurrence of leaks and extends the life of the product.

A 304 stainless steel elbow in a piping system connects two pipes with the same or different nominal diameters in order to bend the pipe at an angle.

304 stainless steel elbow remove stainless steel surface oxidation chemical process known as delayed corrosion rate of the metal, is the pickling passivation of stainless steel. Removal of oxidation and rust from the steel surface. A very thin passivation film is formed on the surface, which completely isolates the metal from corrosive media, preventing contact between the metal and corrosive media and forming a passivation state to achieve anti-corrosion effect. The pickling and passivation process cleans the surface by degreasing - clean water rinsing - pickling - passivation - clean water rinsing - blowing dry.

After manufacturing, the pickling and passivation pretreatment of stainless steel pipe fittings is carried out on 304 stainless steel elbows according to the requirements of the process documentation. Surface treatment: remove spatter, oil, oxidation skin, etc. Clean both sides of the weld seam and weld slag, clean them, remove them with stainless steel wire brush, stainless steel scraper or grinding wheel, and rinse with clean water after removal. Use gasoline or detergent to remove dirt from the surface of pipe fittings. When the oil is serious, please use 3-5% alkaline solution to remove the oil and rinse with water. Oxidation of stainless steel hot-finished parts can be removed by mechanical sandblasting. The sand must be pure silicon or aluminum oxide. Rinse with clean water (no more than 25 mg / l of chloride ions in the water). Establish safety measures for pickling and passivation and determine the necessary appliances and labor protection supplies.
