- What is the difference between slip on flange and weld neck flange?The Weld Neck Flange is easily recognizable by the hub that gradually tapers from the bolted connection to the pipe. At the Point of Weld on the Weld Neck it is supplied with a specific bore to mate with the attaching pipe or fitting. This connection is made with a full penetration butt weld, this pProduct knowledge September 01, 2021
- RELIABILITY AND MAINTAINABILITY OF IN-SERVICE PIPELINES NO.2All in-service pipelines encounter deterioration due to environmental effects. The deterioration is a time-dependent process which makes the structural integrity of pipelines a time variant characteristic. Advanced mathematical methods which employ probability theory need to be used for time-dependeProduct knowledge September 10, 2021
- CARBON STEEL THREADED FLANGESThreaded flanges, also sometimes referred to as companion flanges / screw flanges / NPT flanges, contain a female NPT thread in the center for connection to male NPT threaded piping. Threaded flanges are common when creating reducing connections. Other thread styles are available for machining, asidProduct knowledge October 27, 2021
- Methods of Pipes ManufactureMethods of Manufacture.The pipe is manufactured by one of the following processes:Seamless (SMLS) pipe is made by a process that does not involve welding at any stage of production.Welded (WLD) pipe is made using an automatic welding process with no addition of filler during the welding process.HeavProduct knowledge August 27, 2021
- Instrument TubingInstrument TubingTubing is normally small-diameter seamless pipes made of high-strength material like carbon steel, copper, stainless steel, titanium, Hastelloy, Monel, etc. They have higher flexibility compared to piping, therefore require less fitting. They can be bent to form angles and fit in thProduct knowledge October 22, 2021
- LENGTH OF PIPESLengthUnless otherwise indicated in the purchase order, pipe should be supplied in the following lengths:The average length of pipes in one order should be not less than 11.6 m with a minimum of 95% of pipes between 11 and 12.2 m in length.No pipe should be less than 10 m in length.No pipe should beProduct knowledge October 15, 2021
- CAST STEEL GATE VALVEThe cast steel gate valves are manufactured according to API, ANSI, ASME standard, for industrial applications. The features of these cast steel gate valves are: outside screw and yoke, bolted bonnet, flexible or solid wedge, rising stem with top sealing. Standard materials are A216WCB/F6, other matProduct knowledge September 29, 2021
- PIPING MATERIAL GUIDEWhen all the piping specifications have been defined and initial quantities identified by the Material Take-off Group, the piping material engineer is responsible for assembling the requisition packages.The Procurement Department will break the piping requirements into several requisitions, so thatProduct knowledge November 05, 2021
- Forged fittings vs. Buttweld FittingsForged fittings are used for piping systems below 2 or 4 inches in diameter (4″ for 2000#/3000# fittings, 2″ for 6000#/9000# fittings), whereas buttweld fittings are used for larger diameter piping.The two main types of forged fittings are the so-called socket weld fittings (which are connected toProduct knowledge September 22, 2021
- CORRUGATED SHEETSCorrugated panels are manufactured through a cold-form process where they are pressed and then roll formed to create the desired corrugated shape. The corrugations within the steel increase the overall tensile strength, making it resistant to increased impact and weight loads. The steel’s corrugatedProduct knowledge September 06, 2021
