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.

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.

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.

There are roughly five types of surfaces that can be used for stainless steel. They can be combined to produce more end products.The five species are:1. rolling surface processing2. mechanical surface processing3. chemical surface processing4. mesh surface processing and color surface processingThere are also some special surface treatments, but no matter which one is specified, theFollowing steps should be followed:1. Work with the manufacturer to agree on the required surface processing, it is better to prepare a sample as the future batch production standards.2.

Corrosion resistanceInternational corrosion resistance of materials according to the annual corrosion rate is divided into three categories, the first category for complete corrosion resistance, the corrosion rate is less than 0.1mm / year, high-quality stainless steel belongs to such materials; the second category for still corrosion resistance, the corrosion rate of 0.1-1.0mm / year, belongs to the general stainless steel; the third category for corrosion resistance, the corrosion rate is greater than 1.0mm per year.Cold rolled descriptionCold rolled: Hot rolled coil is used as raw material,

All steels have the same basic iron and carbon composition, but stainless steel also contains a healthy dose of chromium—the alloy that gives stainless steel its famous corrosion resistance.There are multiple grades called stainless steel, each with slightly different alloy composition, and therefore slightly different physical characteristics.Stainless steel must contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.

The specification of the pattern plateIn fact, its specifications are mainly composed of thickness and width.
