Coal Mill KVM200F Hydraulic System of Conch Kawasaki Quality of the working medium should be analyzed on a regular time. Generally, check-up once a year. 5.6、,。

Like Lap Joint flanges, the two-part design means the rolled angle ring and backing flange can be comprised of different materials for added flexibility and cost optimization potential.An example of this would be using a 316/L SS rolled angle ring with a Carbon Steel, Galvanized backing flange. The backing flange is also free to rotate on the pipe, allowing for easier alignment.

Other common flange materials include Monel, Inconel, Chrome Moly, and many others depending on the application. The best option for your needs will depend on both the system in which you intend to use the flange and your specific requirements. Common Flange Types and Characteristics. Flanges are not a one-type-fits-all sort of solution.

Work area: A place at a work site where a worker is, or may be, present during work or during a work break. Job Safety Analysis (JSA): Job safety analysis is a procedure which helps integrate accepted safety and health principles and practices into a particular task or job. In a JSA, for each basic step of the job, it is to identify potential

The Ring Type Joint (RTJ) gasket is a forged ring that fits into the machined groove of an RTJ flange. The ring-type joint gaskets are either octagonal or oval in cross-section. RTJ gaskets are generally used for high pressure and high-temperature applications. It's widely used in refinery, petrochemical and oil field drilling industries.

Process duct work conveys large volumes of hot, dusty air from processing equipment to mills, baghouses to other process equipment. Process duct work may be round or rectangular. Although round duct work costs more to fabricate than rectangular duct work, it requires fewer stiffeners and is favored in many applications over rectangular ductwork.

the bolt and/or casting which could result in pipe joint separation. Under torquing the bolts may result in lower pressure retention capabilities, lower bend load capabilities, joint leakage and pipe joint separation. Pipe joint separation may result in significant property damage and serious injury. CAUTION: Use of an impact

Torque loss. Torque loss is inherent in any bolted joint. The combined effects of bolt relaxation, (approximately 10% during the first 24 hours after installation), gasket creep, vibration in the system, thermal expansion and elastic interaction during bolt tightening contribute to torque loss.
