Product performance explanation of seamless elbow
Seamless elbow does not produce corrosion, pitting, corrosion, or abrasion. In the pipeline system, the seamless elbow is a pipe that changes the direction of the pipeline. According to the angle, there are 45 and 90 degrees 180 degree three most commonly used, and other abnormal angle bends, such as 60 degrees according to the needs of the project. The elbow is made of cast iron, stainless steel, alloy steel, calcined casting. Iron, carbon steel, nonferrous metals and plastics. The joint of pipes is: direct welding (most commonly used) flange connection, threaded connection and socket connection. According to the production process, it can be divided into welding elbow, seamless elbow, casting elbow, and so on. A pipe fitting used in pipe installation for pipe bending. Other names: 90 degrees elbow, right angle bend, love and bend.
Seamless elbow application field: the seamless elbow is widely used in oil, chemical, nuclear power plant, food manufacturing, building, shipbuilding, paper making, medicine and other industries. It has different use in different industries and shows the value of use in various industries.
Comparison of seamless elbow and other performance
Environmental protection: PE-RT can be recycled and does not pollute the environment. And PEX can not be recycled to produce two pollution;
The development trend of seamless bend pipe material: the seamless bend material not only has the qualified creep rupture curve, but also the pipe material price is moderate, the construction is convenient and quick, the connection form belongs to the most reliable form at the present stage, and the diameter of the pipe part is larger than the inner diameter of the same specification pipe. There is no mechanical connection in the system, so the system fluid resistance is relatively small.
Two, long term withstand voltage performance, only from the design stress, the GB seamless elbow has the best withstand voltage performance. However, due to various factors, the actual wall thickness of the floor heating pipe is usually 2mm. Under this thickness, all kinds of pipes can meet the requirements of floor heating, and the advantages of seamless elbow pipe can not be reflected.
Three. Low temperature impact resistance: PE–RT and PEX have better resistance to low temperature impact. During winter construction, pipes are not subject to impact and rupture, which increases the flexibility of construction arrangements.
