Elbow   are shorter than   bend . There are many types of elbows, such as seamless elbows and carbon steel elbows, which are two typical elbows. In addition, elbows and bend are different in some aspects. 1. Appearance. The elbow is relatively short compared to the bend. R=1 times to 2 times are elbows, and R>2 times are bend. The radius of curvature of the elbow is small, usually are 6D, while the bend is 40D. 2. Manufacturing process. The bend can be made of straight pipe with one-time molding, which not need to do anti-corrosion. The elbow should be customized, and it needs to do anti-corrosion, which makes it has long lead time. 3. Price. The elbow needs to be customized and need to do anti-corrosion, so that its price is higher than the bend. But it has high cost performance. The bend is easy to be damaged since it isn't do anti-corrosion treatment, but it is widely used in some projects that are not very demanding because of its low price.

Galvanized elbow   is divided into electro-galvanized elbow and hot-dip galvanized elbow. Galvanized elbow has the same function to elbow, so what are its advantages over ordinary elbow? The elbow manufacturer   Xiangjiasteel   tells you what are the characteristics of galvanized elbow? 1. The density of galvanized elbow is only one tenth of that of elbow, and its weight is light. 2. Galvanized elbow has a very unique impact strength performance compared to other elbows. 3. Galvanized elbow has a long service life. As long as the galvanized elbow is used within the specified temperature and pressure range, its service life can be 50 years. 4. The galvanized elbow wouldn't fade and able to anti-ultraviolet and anti-radiation. 5. The elbow can resist the erosion of various chemical substances, acid resistance, corrosion resistance, alkali resistance, and won't rust.

Carbon steel elbow  is used to change the direction of the pipeline on the carbon steel pipe. There are threaded connection and welded connection. According to the angle, there are 45° and 90°180°.   here we briefly describe the application of carbon steel elbows: (1) It not need to take tube blanks as raw materials, which can save the cost of tube-making equipment and molds, and can obtain arbitrarily large diameter and thin carbon steel elbows. (2) Short the manufacturing cycle, which greatly reduced the production cost. And it does not require any special equipment that make it able to do on-site processing for large carbon steel elbows. 　　 (3) The blank is a flat plate or a developable curved surface, so the blanking is simple, the accuracy is easy to guarantee, and the assembly and welding are convenient. 　　 (4) Carbon steel elbows are good for pipeline series in petroleum, gas, chemical, hydropower, construction and boiler industries etc.

 The  elbow  is a connection pipe fitting used to connect pipes and change the direction of the pipe in installation, so that the pipe can be turned at 90°, 45°, 180° and various degrees. Bending radius ≤ 1.5 times of pipe diameter is elbow, bending radius> 1.5 times of pipe diameter is bend. Technical requirements for the produce elbows: It is required to control the radius of curvature. For example, if the radius length is 1.5D, then the radius of curvature must be within the required tolerance range. Since most of these pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, with a certain angle and a certain side. This requirement is very strict. For the welding requirement, the steel material of the connected pipe should be the same. 1. 1.5 times the center height of the elbow A = diameter * 1.524, which is the diameter D * multiple, and the result will be the number after the decimal point is rounded to the nearest whole...
