The other end of the Weldolet also has beveled that that is used to connect to the branch line by welding. https://blog.projectmaterials.com/pipe-fittings/weldolet-threado Proper use of Weldolets, or for that matter any integrally reinforced branch connection fitting, all depends on what piping code you are working with. ASME B31.1 and B31.3 show MSS-SP-97 as a "listed standard". In these codes you need to specify your pipe header size/thickness and your branch size/thickness and the material spec for the fitting. For example, an extra strong Weldolet used on extra strong pipe of the equivalent material provides 100% pipe strength. 2000 lb O-lets are good to the pressure rating of Sch 80 pipe and 3000 lb O-lets are good to the pressure rating of Sch 160 pipe. I forget what 60 Advertisement. Testing; Certificates; Production Materials; ISO9001 Quality; Quality Resources; SDS; Canadian Extra Strong. As the professional weldolet pipe fittings supplier, Golden Highope, provides two types of weldolets for you. Forged Pressure Seal Valves. The values shown are based upon a corrosion allowance of 0.05 inches for sizes 1" and smaller. These ratings are based on the ASME Codes for Pressure Piping. weldos are specified by required minimum working pressure. 2000 psi is a typical spec. Does it have 2000 or another working pressure rating forge To make a 90 degree tube branch, weldolets are utilized. Reducing size means the branch size is smaller than run size. Pipeline Design. Thredolet. ASME B16.5 Flange. These ratings are based THE WELDOLET PROVIDES 100% PIPE STRENGTH FOR ALL SIZES, WEIGHTS AND SCHEDULES. MechD, to add a bit of additional information.. you don't need to do branch reinforcement calcs, because the weldolet is precertified for a given p Extra Strong. 20 in X 1 in weldolet should have sch 40 X sch 160 in its description. SW Fitting = Class 3000/ Class 6000/ Class The ends are bevelled to facilitate this process, and therefore the weldolet is considered a butt-weld fitting. Threaded (NPT) Fitting = Inch To 8 Inch. Forged Weldolets are available in Carbon Steel, Stainless Steel, Alloy Steel & Low Temperature Carbon Steel Grades. *** Upon prolonged exposure to temperatures about 775o the carbide phase of carbon steel may be As people had mentioned Weldolets are pressure rated so as long as you specify the weldolet with the correct pressure rating above your pressure then "job's a good one". There is no need to perform calculations as these fitting designs have been proof tested by the fabricator. Branches are integrally reinforced so no calcs required. Perfect. manufactured in 3000# and 6000# classes. Table provides dimensions of reducing size weldolets for run and branch pipe wall thickness of schedule STD. THE WELDOLET PROVIDES 100% PIPE STRENGTH FOR ALL SIZES, WEIGHTS AND SCHEDULES. Weldolet Welding Fittings are rated the same as seamless steel pipe. These ratings are based on the ASME Codes for Pressure Piping. For example, an extra strong Weldolet used on extra strong pipe of the equivalent material provides 100% pipe strength. Metric. Standard. Weldolet Features. Duplex Stainless Steel Olets - Duplex SS ASTM A182 F304, 304H, 309, 310, 316, 316L, 317L, 321, 347, 904L. The pipe weldolet size, material code, pressure rating and thread code should be carefully checked before purchasing. Raw Materials Schedule 160. Inch. Likewise, a standard weight Weldolet has the same ratings as standard weight pipe and provides 100% pipe strength when used on standard weight pipe. No, spec the minimum working pressure, let them certify they've furnish something with a higher working pressure than that, and then . on to the Weldolets are available in sizes ranging from 1/4 through 48, and they are A Weldolet is welded onto the run pipe on one side and the branch pipe on the other side since it has bevelled ends on both ends. Manufacturer Size. you can always accept higher thickness and machine to desired thickness. Does it have 2000 or another working pressure rating forged onto it? Bonney Forge puts out a pretty good catalog at http://www.bonneyforge.com/resources/BC.pdf On page 7 of that catalog you'll find a couple sections Weldolet is the most common of all branch connections, and is welded onto the outlet pipe. MSS SP-97. Pressure Rating : Socket Weld Fittings = 2000LB, 3000LB, 6000LB: B16.9 - Fitting Pressure & Temperature Ratings2. Threadolet considered to a threaded fitting, and it is manufactured in 3000 and 6000 classes. The mainly differences are the connection surface, weldolet ends in plain or beveled to weld on the the branch pipe, sockolet ends in socket type that to insert branch pipe. Threadolet is insert branch pipe and with screw connection. They are WOLR and WOLS. Markets Served; Quality Programs. For low pressure applications a boss could be better. Weldolets are available in sizes ranging from 1/4 through 48, and they are manufactured in accordance with ASME B16.11. Sockolet Greater pressure is compatible, but the expense is higher. The end connection of the Sockolet is suitable for socket welding. Type Of Standards. 4. If you need further details about weldolet dimension and weldolet pressure rating, welcome to check out Golden Highope website and feel free to "We have a Actually, if you look at MSS SP-97, O-Lets are not actually specified by pressure rating. They are given Class rating which you then correlate to a Thanks BigInch but we're still in the early design stage so haven't bought any weldolets just yet. Line pressure ranges from 4 - 16 bar. I've alre Metric Dimensions of Standard Rating Weldolet as per MSS-SP-97. ** Ratings apply in accordance with Sections 1 and 5 of the Code for Pressure Pipe. MechD, As people had mentioned Weldolets are pressure rated so as long as you specify the weldolet with the correct pressure rating above yo API 6A Valves. Nominal Pipe Size Weldolet (Weight in KG) SCH 160 Small size 1/2" 3/4" 1" 1 1/4"1 1/2" 2" 2 1/2" 3" 4" 5" 6" 8" 10" 12" 14" 16" 18" 20" 24" 3/4" 0.11 0.32 3,000lbs Pressure Rating; Code In Stock Inch Size Code Metric Size Code Grade COST QTY Subtotal; SPWOL15# 1/2" - CLEARANCE SPWOL15# 15NB: 316L $ 42.30: SPWOL20# 3/4" - CLEARANCE SPWOL20# 20NB: 316L $ 74.25: SPWOL25# 1" - CLEARANCE SPWOL25# 25NB: 316L $ 86.73: SPWOL40# 1 1/2" - CLEARANCE SPWOL40# 40NB: 316L $ Home; About US; Products. Perfect. Thanks! As I understand threadolets have ratings of 3000 & 6000 which is much higher. Sockolets are used for lower pressure applications, and smaller pipe diameters, but the expense is higher. The other end of the Weldolet also has beveled that that is used to connect to the branch line by welding. Pressure Rating for ASME B16.11 Forged Pipe Fittings. See Note #1 Allowable pressure of pipe varies with code, material strength and temperature anyway and corrosion allowances may be different depending on service fluid and design lifetime, so there is no need for fittings to have a pressure rating to match the pressure of whatever pipe they used to get the2000,-9000 ratings. For example, the WOL14" x 4"Sch40XSTD 16 Mn is British style weldolet while WOL377 x 108 12x816 Mn is a metric weldolet. Weldolet welds can be quire large and can put a lot of heat in to the header pipe. weldos are specified by required minimum working pressure. Weldolet is Compatible with higher pressure and simple connection, cost lower. mss sp-97 are known to offer an outlet from a large pipe to a smaller one, mss sp-97 weldolet is the mostly used branch connection fittings, check mss sp-97 weldolet/ sockolet and threadolet dimensions.
