Sanitary elbow encyclopediaDepending on your requirements, sanitary elbow  can be austenitic or ferritic, and is defined by being seamless and easy to clean, suitable for pharmaceuticals, food and beverage, and drinking water applications.Introduction of sanitary elbow:Material: 304 material and 316L material are two common materials.Product categories: 90 degree long elbow, 90 degree short elbow, 45 degree short elbow, 45 degree long elbow, 180 degree elbow.Connection method: clamp (quick installation) type, butt welding (welding machine) type, thread (slip knot) type.Standard: 3A, DIN,

Laying points of stainless steel elbow in pipeline:1. In order to reduce the heat loss of the stainless steel elbow and prevent thermal deformation, the buried depth of the pipeline should be greater than 1.2 meters. (calculated from the top of the pipe). The burial depth in alpine regions should be appropriately deepened. At the same time, all pipes should be avoided to be laid below the water table.2. For areas where the groundwater level is high or it is difficult to dig deep for other reasons, measures should be taken as far as possible to avoid water insulators before burying the pipes.

Implementation principleThreaded flange is a kind of non-welded flange, which processes the inner hole of the flange into pipe threads, and is matched with the threaded pipe to realize the connection. Compared with the flat welding flange or the butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines where welding is not allowed. Alloy steel flanges have sufficient strength, but are not easy to weld, or the welding performance is not good, and threaded flanges can also be selected.

The appearance of the stamping elbow is fixed. Of course, the appearance of the general stamping elbow is based on the different knowledge of the steel pipe. Therefore, in order to ensure the appearance of the stamping elbow, usually after the steel pipe comes in , If it has not been washed by the rain in the yard, then the stamping elbow is pushed by high temperature, and the appearance of the stamping elbow is generally blue. Of course, if it is washed by the rain, we are heating it through high temperature. , the surface color of the heated stamping elbow is red.

Loose flange: This kind of flange is often used in the case where the medium temperature and pressure are not high and the medium nozzle is highly corrosive. The loose flange is generally used in combination with the flanging short joint, that is, the flange ring is loosely sleeved outside the flanging short joint, the pipe is butt welded with the flanging short joint, and the flange sealing surface is processed on the flanging short joint.In addition, there are flat welding ring and butt welding ring plate loose flange.

Structural features:Threaded flanges manufactured in accordance with ASME B16.5 are similar to sliding flanges, but the holes shall have tapered pipe threads in accordance with ASME b1.20.1. The thread shall be concentric with the axis of the flange opening, and the alignment deviation (perpendicular to the flange face) shall not exceed 5mm per meter. Threaded flanges are NPs 1 / 2 to NPs 24 in size and pressure classes are 150, 300, 400, 600 and 900. The sizes of class 1500 and 2500 are NPs 1 / 2 to NPs 2 - 1 / 2.Class 150 threaded flange has no counterbore.

Precautions when installing stainless steel elbows:  1. When installing, the stainless steel elbow can be directly installed on the pipeline according to the connection method, and installed according to the position of use. Under normal circumstances, it can be installed in any position of the pipeline, but it needs to be sealed to prevent leakage and affect the normal operation of the pipeline.2. When the stainless steel elbow ball valve, globe valve and gate valve are used, they are only fully open or fully closed, and should not be used to adjust the flow to avoid sealing.3.

Advantages of thin-walled 90-degree elbows: excellent wear resistance and continuous use.90° elbows are suitable for piping systems in petroleum, natural gas, chemical, hydropower, construction and boiler industries.The straight seam elbow with any large diameter and relatively thin wall thickness can be obtained by the casting process. The manufacturing cycle can be shortened and the production cost can be greatly reduced. Because it does not require any special equipment, it is especially suitable for on-site processing of large straight seam elbows.

Difference between ANSI and ASME Flanges?The ANSI and ASME terms are most common in metal industries. But many people still don't know the exact difference between ANSI and ASME. They thought that both ASME & ANSI Flanges are the same and there is no difference between them. But that's not right. In this article, we clearly understand the difference between ANSI and ASME Flanges. ANSI and ASME Flanges are the standard flanges designed with specific rules and conditions stated by ASME and ANSI standards.
