High pressure thick wall elbow manufacturer

Description :

　　The application data of high-pressure thick walled elbows is a new type of data with special electrical, acoustic, thermal, mechanical, chemical, and biological properties. It is the main basic data for high-tech fields such as biotechnology and energy technology, as well as national defense construction. At the same time, it also plays a major role in the transformation of certain conservative industries, such as agriculture, chemical industry, building materials, etc. The information on high-pressure thick walled elbows and bends is unique, showcasing innovative applications within a certain range, and to some extent influencing the development of other industries. Application of high-pressure elbow: Connect two pipes with the same nominal diameter to make a 90 degree bend in the pipeline. 1. Divide carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon chromium plating, PPC, etc. by material. 2. According to the production method, it can be divided into pushing, pressing, forging, casting, etc. 3. According to manufacturing standards, it can be divided into national standards, electrical standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc.

　　The main materials for high-pressure thick walled elbows are 20 # and Q235B. The elbow is stamped and formed using a pipe blank with an outer diameter equal to the elbow, which is directly pressed and formed in the mold using a press machine. The data required for producing large-diameter elbows requires some special raw materials for production, which need to be carefully selected and controlled. The raw materials must be chosen appropriately, otherwise the high-pressure elbows produced will not have quality assurance. Alloy thick walled elbows are used in pipelines with fast liquid flow and strong impact force. Alloy elbows made of nickel steel are usually used in pipelines for transporting high concentration oxidizing acids at room temperature. However, they are severely corroded in pipelines for transporting reducing acids, and their concentration is low, resulting in high temperature strength, oxidation resistance, and corrosion resistance. Alloy elbows have a wide range of uses and applications, and have been inspected by the country to meet national standards, ensuring quality assurance. Received unanimous praise from a large number of customers. An alloy elbow connects two pipes of the same diameter, with both ends of the pipe having the same diameter without causing blockage. It has a variety of materials. Widely used, ordinary bronze alloy elbows are quite common in tap water. Aluminum alloy elbows made of manganese steel are commonly used in concrete and mud pipelines due to their strong impact resistance, compression resistance, and wear resistance. They are more wear-resistant and impact resistant, making them more convenient to use. High pressure thick walled elbows not only have good compressive strength, but also need to have other excellent characteristics in different pipeline systems. For example, in concrete conveying pipelines and mud conveying pipelines, high-pressure elbows should not only be able to withstand high pipeline pressure, but also have good wear resistance. In the chemical raw material transportation pipeline system, high-pressure elbows not only have to withstand high pipeline pressure, but also have excellent corrosion and acid alkali resistance. High pressure elbows are generally suitable for pipeline systems in industries such as petroleum, natural gas, chemical, hydropower, fire protection, construction, and boilers.

Hot bending 90 degree elbows, high-pressure elbows, elbows at 45 degrees, 60 degrees, 90 degrees, 180 degrees, 360 degrees, etc. Welcome to inquire and look forward to cooperating with you. Hot pressed thick walled elbows require normalizing and tempering heat treatment, as well as machining ports. The wall thickness should be left with burn damage and machining allowance. The general margin is 10% to 20% of the theoretical wall thickness of the elbow. The smaller the ratio of the wall thickness δ of the elbow to the cross-sectional diameter D, the better the adhesion performance with the mold, but the inner arc of the elbow is more prone to instability and wrinkling. δ - wall thickness of elbow; D - Bend section diameter. If the actual selected outer diameter of the pipe blank is smaller than the Dp value calculated according to the formula, it has good bonding performance with the mold, but the inner arc of the hot pressed elbow is prone to instability and wrinkling. If the actual outer diameter of the selected billet is larger than the Dp value calculated by the formula, the result will be exactly the opposite.
