90 Degree Elbow Astm Carbon Steel Pipe Fittings

Description

Elbow is a common connection pipe in the installation of water heating. It is used for the connection at the bend of the pipe and to change the direction of the pipe. Connect two pipes with the same or different nominal diameter to make the pipes turn at 90 °, 45 °, 180 ° and various degrees. Bending radius less than or equal to 1.5 times of pipe diameter is elbow, and greater than 1.5 times of pipe diameter is elbow. The 90 degree elbow size is generally calculated according to the known pipe diameter, and the bending radius is usually 1.5 times of the diameter. According to different models, 90 degree elbow size is different, and its length radius is also different.

The larger the nominal diameter of the 90 degree elbow, the larger its size. To understand the specific data of 90 degree elbow size, you can find relevant data on the Internet or consult professionals. As the model mark of the corresponding seamless steel pipe, the outer diameter times the millimeter number of the wall thickness. Such as Φ 57 × 3.5, Φ 89 × 4.5, Φ 108 × 4.5, Φ 159 × 6, Φ 273 × 6, Φ 325 × 8. 90 degree elbows on the market are commonly used with r = 1.5D, and then r = 5D. They are also customized as required. There is not much difference between 90 degree elbow and 45 degree elbow. The biggest difference is the angle of elbow. According to the actual construction situation, choose different angle elbow products. For example, if a right angle bend is required for pipeline routing, 90 degree elbow products are required. If only 45 degree bend is required, 45 degree elbow is selected.

For the same project, if two 45 degree elbows are selected, the price list is more expensive than using one 90 degree elbow, which is not very cost-effective. 90 degree bend forms a right angle, while a 45 degree bend is an obtuse angle. It is not allowed to weld two 45 degree elbows into 90 degree elbows for use, because the elbows are the concentration area of stress on the pipes, and most of the stress of expansion and cooling deformation is released at the elbows. In addition, the weld itself should be a weak link, and the fatigue deformation will soon cause crack damage, which has a great hidden danger. Therefore, it is not convenient to plan for a while, and ultimately cause huge losses.

Technical data sheet
