Stainless Elbow Fitting
What is a stainless elbow fitting?
In a piping system, stainless elbow fitting is a pipe fitting that changes the direction of the line. According to the Angle, there are 45° and 90°180° three most commonly used. In addition, according to the engineering needs also include 60° and other abnormal Angle elbow.
Stainless steel is usually increased on the basis of carbon steel with a high proportion of Cr, Ni and other alloys, the proportion of content can reach more than 20%. Standards and grades commonly in ASTM A403 WP 304/304L, 316/316L, ASTM A270 etc. It has higher strength and higher corrosion-resistances than carbon steel elbow.
The production process of stainless elbow elbow:
The production process of elbow is divided into push system and pressing two kinds. Pushing process is small diameter steel pipe to push large diameter elbow, serious wall reduction; The pressing process is the same caliber pressing, suitable for thick wall products, will also produce wall reduction but not as serious as the pushing process.
The temperature of elbow pushing is related to the wall thickness of the material. The thicker the wall thickness, the higher the temperature of the pushing, and the different temperature of the pushing of different materials.
Knowledge of elbow manufacturing process:
I believe you are curious about elbow manufacturing production, let’s understand the knowledge process of elbow manufacturing production.
1.The elbow is usually connected directly to the pipe or flange. The metal structure of pipe fittings is often damaged when connected. So in order to have a strong connection welding quality, when the elbow production will leave a groove at the end of the elbow. The groove is set at a reasonable Angle so as not to make the bend too thin or too thick. In this way, the rigidity of the elbow can not be damaged in the process of connection.
2. Elbow in the manufacturing process need to be surface treatment. Treatment needs to be painted on the surface of the elbow, or sand blasting. In this way, the elbow can be preserved and transported.
3. Elbow in the production of the general use of these methods: stamping method, roll method, cold bending method, push method, and so on. Taking cold pressing as an example, this production method is to select reasonable pipes and directly use mechanical bending pipes to make elbows. This production method is characterized by low cost and can be used in a wide range of applications. However, it also has certain disadvantages, such as the metal structure of the elbow itself will be damaged in the process of cold bending, which will make the elbow become weak and reduce the service life of the elbow. So in some requirements of the more strict pipeline environment, should try not to use this elbow.
