OS & Y WCB API600 Standard Flexible Wedge Gate Valve For High Temperature And High Pressure

 

 

Descriptions

 

TEKO Gate Valves are of conventional full bore with flexible wedge that provides flexure of the gate seating surfaces. The two inclined seats allow for tight shut off even against high pressures. Outside Screw and yoke design.TEKO valves are serialised products being some parts interchangeable to other valve types thus increasing the assembly flexibility. Gate valves are bi directional valves and of easy operation being widely used in power, chemical and oil industry.The range is also comprehensive of Pressure seal valves, which are used for high temperature – high pressure service, specially on power plants.

Difference among standard of ASME B16.5, ASME B16.47 Series A aand Series B

 

ASME B16.5 standard covers Steel Pipe Flanges and Flanged Fittings from size 1/2" through 24" in pressure class 150 to class 2500. It covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings. Two very important flanges such as weld neck flange and blind flanges are very commonly used in piping systems. The term "B16.5" or "B16 5" is used interchangeability and refers to same standard.The standard ASME B16 5 (ANSI B16 5) only covers size up to 24 inches. For bigger sizes, ASME B16.47 standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, and testing for pipe flanges in sizes NPS 26 through NPS 60 and in ratings Classes 75, 150, 300, 400, 600, and 900.

 

However, the standard ASME B16.47 is further divided into ASME B16.47 series A and ASME B16.47 series B flange for Blind flange and Weldneck flange.Term B16.47 or B 16 47 or ANSI B 16 47 are all used interchangeabily and refers to the same standard.

 

Generally speaking, ASME B16 47 Series A flanges are much thicker, heavier and stronger than Series B flanges in the same size and pressure rating thus can withstand more external loading than Series B type. ASME B16.47 Series B flanges need more but smaller fasteners (bolts & nuts) than Series A flanges and have a smaller bolt circle diameter than that of Series A flanges. The smaller bolt circle diameter results in less flange movement after installation. Both Series A and Series B standards define weld neck flanges and blind flanges in raised face type (RF) but only Series A defines ring type joint (RTJ) flanges from Class 300 through Class 900 within this standard. From a commercial point of view, ASME B16.47 Series A flanges are more expensive than ASME B16 47 Series B flanges.
