90 degree elbow-manufacture,factory,supplier from China

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.

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.

Stainless steel can be roughly divided into flat steel and concave-convex steel. The flat steel plate can be divided into three categories: mirror steel plate with surface light reflectivity greater than 90%; The reflectivity is 50%~90% of the light plate; Matte steel plate with reflectivity less than 50%.

The utility of stainless steel flux cored wire is particularly MAG welding, MAG welding has the subsequent characteristics1) Compared with manual welding, welding speed can be advanced 2-4 times, its welding efficiency is as much as 90%(stainless steel electrode only 55%)2) to the current, voltage adaptation range, welding conditions are easy to set, easy to conduct semi-automatic and automated welding. 3) Good slag removal, welding pass surface gloss. In addition, the splash is very small, the arc stability is good, X-ray qualified.

The high market demand for precision stainless continues to increase at an exponential pace. Widely used across many industries including mechanical, civil and industrial, the material has been the subject of a recent Future Market Insights (FMI) report, which forecasts that the precision stainless steel market looks set to reach a massive US$3.2bn (around £2.53bn) by the year 2029.There are many reasons for the popularity of precision stainless steel, including the fact that it comes in a great many forms and boasts easy, reliable workability.

Flanges play a very fundamental position in connecting pipes, valves, and different industrial equipment. They furnish effortless get admission to at some point of cleaning, repairs, and inspection. In heavy industry, flanges want to be chosen cautiously considering they can structure a susceptible factor in the system.WHY CHOOSE STAINLESS STEEL FLANGES?You want to get value for your money. Here is why stainless steel flanges are worth the investment.Resistance to CorrosionIn every metal application, corrosion is an important consideration.

Stainless steel 304, 316 difference：First, 316 stainless steel containing Mo, corrosion resistance is better than 304 stainless steel in a high temperature environment, so in a high temperature environment, engineers will generally choose 316 material parts.Second, there are also differences between the two from the brand; 304 stainless steel corresponding to the Chinese brand 0Cr18Ni9; 316 stainless steel corresponds to the Chinese brand 0Cr17Ni12Mo2.Thirdly, 316 mainly reduces Cr content, increases Ni content and increases Mo2%~3%.
