11 -“Forged Fittings, Socket-Welding and Threaded” the below table shows the schedule of pipe corresponding to each class of fitting for rating purposes. g. They are given as a class designation and what I understand this classification is not the pressure rating. We manufacture the 3000# Pipe Fittings for use in the water supply, For example, if you are using Schedule 80 pipe, you usually need a Class 3000 fitting to match the pressure capability. 1 These unions shall be designated as Class 3000 or Class 6000, socket welding or threaded and shall carry ratings shown in Table 4 for Class 3000 or Table 5 for Class 6000. The length of useful thread (B plus threads with fully formed roots and flat crests) shall not be less than L2 (effective length of external thread) required by I am aware that there is a matching pipe wall thickness for a given class of socket weld fitting (Sch80/XS pipe goes with a 3000# class socket weld fitting for example) My question is if that Good Answer: Hi solidspaces, A quick Google showed Class 300 are Cast Malleable Steel fittings rated at 300 psi while the Class 3000 are Forged Steel rated at 3000 psi. 11. , Schedule 40, 80), Share to: Sockolet Size Range: 1/8" - 4” / DN6 - DN100 Pressure Rating: Class 3000lbs, 6000lbs Standard: MSS SP-97, GB/T 19326 Material Grade Dear experts, Can any body suggest what does rating 3000,6000 and 9000 etc. There are three different pressure classes available for socket welded, 3000, 6000 and 9000. . Threaded fittings are available ilable in class 3000 and 6000. Socket Weld Threaded Piping Fittings Ratings for Threaded Fittings are Class 2000, 3000, 6000. The As per ASME standard B16. eg: 2000#, Class 3000 / 6000 forged fittings are divided into socket weld fittings and threaded fittings according to the connection method. 2. If I could get any information on pressure ratings of threaded fittings. This is characterized by its pressure-bearing capacity. If you use a Class 2000 fitting on a Schedule 80 pipe, the fitting becomes the For pipes in schedule 80/XS, class 3000 socket weld fittings are applicable; for pipes in 3000 psi socket weld fittings; and for pipes with greater wall thickness, All The Fittings You Need al grades for any application. Where the Schedule Pipe (Wall Thickness Rating Pipe) is a key parameter used to standardize wall thickness in industrial piping systems, and its value (e. It appears to my novice eyes that SCH rating is These fittings are designated as Class 2000, 3000, and 6000 for threaded end fittings and Class 3000, 6000, and 9000 for socket-weld end fittings. If there is a weld neck flange without any schedule (which is not the case generally), then in that case we should match the schedule of the pipe Our most common is Class 3000, however we also offer Class 2000 & 6000; Class 2000 threaded are Schedule 80 rated (only available in female 45°, 90°, and Tees). In general, Class 3000 is for use with Schedule 80 pipe, 6000 - One of the problems I have run across is not being sure when a pipe schedule needs to be specified alongside the fitting/flange rating. 11 and MSS SP-97 Flat Sockolets are Dimension B is minimum length of perfect thread. Choice of Class depends on thickness schedule of pipe, as given in ASME Solitaire Steel is a Leading Distributor of sch 40 vs sch 80 Piping Products. Pressure classes, schedules and weights of pipes for threaded & socket welded fittings. ASME B16. Schedule 40 is, of course, thicker than schedule 20; schedule 80 is thicker than schedule 40; SIZE IDENTIFICATION In the case of reducing tees and crosses, the size of the largest run opening shall be givern first, followed by the size of the opening at the opposite end of rhe run. 11 design class 3000 couplings are typically approved with NPT threads if without customers detailed instruction, but can be customized. The Class 3000 Stainless Steel Pipe Fittings are forged, rolled or welded during production. means as per ASME B 16. Socket Weld fittings are availabl in class 3000, 6000 and 9000. What should test pressure for items produced in rating 9000. Notes: Class 3000 is to be used with schedule 80 pipes Dimensions and tolerances by ASME B16. Learn the Differences Between Schedule 40 and Schedule 80 Based on Application.
