The difference between the stainless steel elbow and the carbon steel elbow is mainly due to the difference in material. The chemical composition of the elbow will keep the surface of the elbow from rusting for a long time and will not be corroded.
In a piping system, an elbow is a pipe that changes the direction of the pipe. According to the angle, there are three most commonly used 45° and 90°180°, and other abnormal angle elbows such as 60° are also included according to engineering needs.
The stainless steel elbow processing is based on the power of a conventional or special stamping device, so that the sheet material can directly withstand the deformation force and deform in the mold, thereby obtaining the production skill of the commodity parts of a certain shape, scale and function. Sheets, molds and their devices are the three elements of stamping. Because the stainless steel elbow pipe has the advantages of inner wall lubrication, low heat medium activity resistance, acid and alkali resistance, long service life and convenient installation.
The stability of the stainless steel pipe can effectively prevent the pollution caused by the material. The stainless steel pipe has high strength, can withstand strong vibration and impact, has the characteristics of no water leakage, no bursting, fireproof and earthquake resistance, and is widely applicable. Besides disinfection and sterilization, it is not necessary to control the water quality. At the same time, there is no corrosion and dirty exudate. If the water stays in the pipeline for a long time, it will not affect the water quality and prevent secondary pollution. Obviously, this is a health barrier.
Development trend of stainless steel elbow pipe: GB stamping elbow material not only has a qualified creep breaking curve, but also the price of the pipe is moderate, the construction is quick and convenient compared with other varieties, and the connection method is attributed to the most reliable mutual fusion hot melt fusion in the current period. The method, the hole diameter of the pipe part is larger than the inner diameter of the same standard pipe, and the system fluid resistance is relatively small because there is no mechanical connection method of local shrinkage in the system.
Use and maintenance of stainless steel elbow
In the process of home decoration, stainless steel elbows are used and maintained in a correct and reasonable way, which can prolong the service life. The main methods are:
- Long-term storage of stainless steel elbows should be checked on schedule. The exposed surface should be kept clean, dirt removed, and stored neatly in a place where the air is dry and dry. It is strictly prohibited to be stacked or stored in the open air. Always keep the stainless steel elbow dry and ventilated, keep the cleaner clean and tidy, and store it according to the exact storage method.
- The stainless steel elbow ball valve, stop valve, gate valve use, only for full or full closure, so as to avoid erosion of the sealing surface, accelerate wear. The gate valve and the upper thread stop valve have a reverse sealing device, and the hand wheel is screwed to the uppermost position to prevent the medium from leaking from the packing.
- When installing, the stainless steel elbow can be directly installed on the pipeline according to the connection mode, and installed according to the position used. Under normal circumstances, it can be installed at any position of the pipeline, but it is easy to check the operation. Keep in mind that the flow direction of the stainless steel elbow should be upward from the longitudinal valve. The stainless steel elbow can only be installed horizontally. Stainless steel elbows should be carefully sealed during installation to prevent leakage and affect the normal operation of the pipeline.
