Large diameter elbow to push the system push the system, the wall thickness should not change under normal circumstances, but if because Tools reason, some places will be less w all phenomenon occurs, it is generally mentioned material, wall thickness to add some margin, such as the elbow is the wall thickness of 8.18mm, generally mentioned tube of about 8.5mm, to prevent the push the system, due to the local less thick ultra-poor. Whole good shape after elbow outside diameter, wall thickness dimensions are required. The following finishing process, after shot peening, the the elbow both inside and outside surface of the iron oxide skin removed, both ends of the groove processing to facilitate welding. Checked, after the process of playing steel word, spray paint, packaging, ready for shipping. Above 24 〃 seamless steel pipe elbow production methods as a raw material, after more than 24 〃 more than 600mm, maximum elbow between 2.032 m to 2.80 m, with a steel plate to do.stainless steel reduce
Large diameter elbow push the system has some differences with other production and processing of the elbow, need to be produced according to certain criteria, to ensure that the production of the push system elbow to show good use of the value in use. Elbow push the system molding process and production processes need to be in a certain space and venue production, production to comply with certain processes and process stainless steel pipe fittingsstandards. The elbow fittings has a different production technology and processes, processing, production and processing under certain circumstances, elbow fittings of the different nature of processing need to take certain precautions. To push the system elbow down, push the system to do long radius elbow first to the first selected steel pipe specifications proposed pipe material, the choice of quality steel production. Elbow push the system to certain expansion ratio, by theoretical calculations, and general expansion ratio between 33% -35%, pushing down the back. Short radius 219mm Usually the enlarged diameter was 50%. After selecting the raw material, the press push system elbow Specifications feed, and then consider the radius of curvature, for example, 90 ° elbow, through its curvature can be calculated Multi long material can be processed to a 90 ° elbow. By theoretical calculation can be calculated, then the length is cut to length for cutting. Finally, the material thermal push the system.Sanitary pipe fittings
