- RELIABILITY AND MAINTAINABILITY OF IN-SERVICE PIPELINESABSTRACT OF PIPELINES This article introduces the most common type of pipelines used in industry. Pipes categorized based on their material type and their areas of usage as well as their overall characteristics are mentioned.At the first step of reliability analysis and service life prediction of pipe.Product knowledge July 30, 2021
- What is the difference between RF and FF flanges?Flat face (FF) flanges are similar to the RF flanges, but they do not have the raised area like the RF flange. Instead, the whole surface is flat.They are commonly used in low temperature and pressure environments such as pump suctions or water treatment flanges.Product knowledge August 18, 2021
- Case Studies on the Application of Structural Reliability Analysis MethodsThe consequence of pipeline failure can be economically, socially, and environmentally devastating, which can cause massive costs for repair, enormous disruption of daily life, extensive pollution, and even human injuries. This necessitates a comprehensive procedure to estimate the likelihood of pipProduct knowledge September 18, 2021
- TWO TYPES OF LINE PIPIE,SEAMLESS AND WELDEDSeamless pipe is formed from a cylindrical bar of steel. The bar is heated to a high temperature and then a probe is inserted to create a hole through the cylinder. The cylinder is then transferred to rollers which size the cylinder to the specified diameter and wall thickness. A few mills can produProduct knowledge October 29, 2021
- GATE VALVE VS. BALL VALVEGate valves tend to be less expensive than ball valves, but are more susceptible to corrosion. Over time, the internal stem that connects the knob to the gate becomes increasingly likely to fail. They are often used with larger pipe diameters of two inches and up. Ball valves are more effective at fProduct knowledge October 20, 2021
