Pressure Rating Table for Carbon Steel Pipe. Notes to the Table of Allowable Working Pressures. This data is intended to provide a general guide. It must not be relied upon in the absence of competent professional advice.
Pressure Ratings of Steel Pipe Based on ASTM A53 Grade B or A106 Grade B Seamless ANSI 831.1, 1977 with allowances for connections and fittings approx. 25%.
Calculations are for seamless pipe to specification ASTM A312/A312M (austenitic grades) or ASTM A790/A790M (grade 2205). An additional weld joint efficiency factor (typically 85%) must be allowed for standard welded pipe, and allowance made for corrosion or wear loss if appropriate.
Maximum pressure ratings for pipes per. API 5L Carbon Steel Pipe and A-106, A-53, A333, A334. Minimum tensile strength 60 ksi (60000 psi). This table defines the maximum pressure rating for the specified industry standard pipes, Schedule 160, Schedule 40 and Schedule 80.
Pressure (psig) and temperature (deg F) ratings for A-53 B and A-106 B, A333, A334 and API 5L carbon steel pipes - temperatures ranging 100 degF - 700 degF. Ratings calculated (see below the table) according ASME B31.3-2002 Table K-1 for plain end standard seamless carbon steel pipes and tubes spec. no. A-53 B, A-106 B, A333, A334 and API 5L.
Pressure Ratings and End Loads for Victaulic Couplings on Steel Pipe. Style 07 Zero-Flex Rigid Coupling. Style 77 Flexible Coupling. Style 741 Vic-Flange® Adapter. Pressure Ratings for Styles 07, 77 & 741. Table continued on page 2. See page 12 for important notes.
This document provides pressure rating tables and notes for carbon steel pipes. It gives the maximum allowable operating pressures for carbon steel grade B pipes in various sizes, schedules, and wall thicknesses at different temperatures.
