High-Quality Stainless Steel B8 B8m Stud Bolts
Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. A193/A193M(A194/A194M) covers both inch and metric series products. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure service.
This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8Â threads per inch (tpi) for diameters above one inch.
Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.

Front Six Axis Brushless Winding Machine
According to the winding mode can be divided into: flat winding machine, ring winding machine, flying fork winding machine, three-dimensional winding machine. According to the actual work of the winding machine and the previous fault records, it can be found that the accidental fault caused by the design or production process defects of the winding machine can be solved by constantly modifying and improving the system software or hardware. These modifications are continuously provided to maintenance personnel in the form of maintenance information. Through these customer feedback, the company can take this as the basis for troubleshooting, correct and thorough troubleshooting, and the reasonable feedback from users is also a powerful help for our company to continuously improve.
In a word, the first step of winding machine maintenance is to identify the real cause and location of the fault as soon as possible according to the fault phenomenon. There is no strict limit in the actual application of these fault handling methods. Sometimes only one method can eliminate the fault, or multiple methods may be needed at the same time. The effect mainly depends on the experience of the maintenance technician and the depth of his understanding and mastery of the system principle and structure. This is not only the quality that the maintenance personnel must have, but also puts forward high requirements for the maintenance personnel. It requires the maintenance personnel of the CNC winding machine to be familiar with the structure and design idea of the winding machine and the performance of the CNC winding machine. Only in this way can the cause of the fault be quickly found out and the fault location be judged, In order to carry out on-site mapping of some circuits and parts in maintenance, as a senior maintenance personnel, they should also have the ability to draw engineering drawings.
