PIPE FITTINGS. Established in 1989, HEBEI XINFENG HIGH PRESSURE FLANGE AND PIPE FITTING CO., LTD (XINFENG) specializes in the manufacture of flanges, butt weld pipe fittings in standard as well as special parts and forgings according to customer drawings. QUALITY & CERTIFICATE.
The valve cages special design provides positive seating and extended life. Connecting rods are either a special alloy aluminum or bronze, at higher pressures, oversized for strength and load disbursement. Don't forget to get some extra pump oil. Our high pressure pumps will come as "plumbed pumps".
17-11-2009· Design code is B31.3 and flange material was A105. Referencing ASME B16.5 Group 2.1.1, the 100 deg F pressure rating was 740 psig. Section 2.5 of the same standard states that the maximum test pressure is 1.5 times the 100 deg F pressure rating (740 psig x 1.5 = 1110 psig).
Flanges can withstand different pressures at different temperatures. As temperature increases, the pressure rating of the flange decreases. For example, a Class 150 flange is rated to approximately 270 PSIG at ambient conditions, 180 PSIG at approximately 400°F, 150 PSIG at approximately 600°F, and 75 PSIG at approximately 800°F.
High Pressure: A service for which the owner specifies the use of Chapter IX [of B31.3] for piping design and construction… considered to be in excess of Class 2500 (6000 psi, 42 MPa). There are no specified pressure limitations for application of these rules. [K300(a)] BECHT ENGINEERING COMPANY, INC. High Pressure Piping -6 General
These flanges are available in weld neck, slip-on, and threaded end types. Reducing flanges are an economical way to make transitions between pipes of different sizes, however, due to high-pressure loss, they are rarely used in piping. ASME B16.5 covers the dimensions of reducing flanges.
flange adapter. These products have pressure ratings as high as 350 psi with safety factors from three to one to five to one. This is possible because we use 0-ring seals at the flange face. EBAA uses a five to one safety factor on a pressure rating of 350 psi to mean that …
17-04-2003· Machined flanges work well in high-pressure applications. Available in the same basic materials as sheet-metal flanges, they are more robust and use seals, O …
20-09-2017· Expander flanges are a cheaper (and lighter) solution compared to the combination of a buttweld reducer and a standard flange (which is the standard solution for pipe bore increases above 2 sizes). The most common materials for expanding flanges are A105 (high-temp. carbon steel), A350 (LTCS) and ASTM A182 (stainless steel and above).
30-05-2021· They provide easy and low-cost installation and are ideal for lower pressure applications. Typical slip-on flange. Image Credit: thepipefittings.com . Socket weld flanges are ideal for small-sized, high-pressure piping. Their fabrication is similar to that of slip-on flanges, but the internal pocket design allows for a smooth bore and better fluid flow.
20-09-2017· the class 300 flange (bigger and stronger, but with the same bore size) withstands 570 psi at the same temperature of 600 degrees F°. finally, a class 2500 flange of the same size bears 34 times more pressure than the class 150 rated flange, reaching a whopping 4730 psi rating at 600 F°!
elements of bolted flanged joints - Design, Component quality, Quality of execution and Bolt . tension. Only if all 4 elements are correctly controlled can you effectively achieve leak free performance of your bolted joints and Ed's current work is focused on developing effective flange management regimes with refinery operators throughout Europe.
Weld neck flange is the most widely used type in process piping. It gives the highest level of joint integrity due to Butt-welded with a pipe. These types of flanges are used in high pressure and temperature application. Weld neck flanges are Bulky & costly with respect to other types of the flange.
10-02-2020· In high pressure and high (or fluctuating) temperature situations, primarily in the oil and gas industry the long welded neck flanges (often abbreviated to LWN) are used. The long neck guides the pipe into the flange itself and offers reinforcement that is not possible with a standard welded neck flange.
4. Use materials with high coefficients of friction 5. Use Loctite on the threads 6. Use an adhesive between the bolt head and flange 7. Use lock washers
Maximum working pressures for cast iron flanged pipe fittings according ANSI B16.1: Maximum Working Pressure (psig) Temperature. (oF) Pressure Class. 125. 250. Pipe Size (inches) 1 - 12.
01-08-2014· FOR Flange Class 300# and Higher class ratings,the "Primary pressure Values" corresponds to higher" Primary temperatures" value of 850 F. A pressure vessel design pressure and test pressure depends on process requirements and there is no manufacturing standard except design …

Flanges - Hydrostatic Test Pressure - Flanged fittings and required hydrostatic test pressure Pressure and Temperature Ratings ASTM A-53, A-106 and API 5L Grade B Carbon Steel Pipes - Metric Units - Pressure (kPa) and temperature ( o C) ratings of ASTM A-106, API 5L and ASTM A-53 Seamless Carbon Steel Pipes - temperatures ranging -29 o C - 450 o C
10-01-2021· The higher the service fluid temperature, the less pressure can be handled by the pipe, fitting and valve body. Please refer to Table II-2-1.1 for Group 1.1. materials. for piping engineer or pipeline engineer, the most useful table is pressure-temperature rating for Group 1.1 ( carbon steel ), Group 1.9 ( Cr-Mo-alloy F11 ) and Group 1.10 ( Cr-Mo-Alloy F22)
10-02-2020· Screwed flange is often used for requirements on small diameter, high pressure. Screwed flanges with a hub have issued requirements ranging from 1/2′′ to 24′′. Pressure class: Class 150 to Class 2,500, PN 2.5 to PN 250 and Facing: RF / RTJ. Screwed flanges are threaded in a bore that matches the pipe's external thread.
