Subchapter VII — Secondhand Vessels

SPS 341.70 Application. This subchapter applies to secondhand boilers and secondhand pressure vessels.

History: Cr. Register, February, 2000, No. 530, eff. 3-1-00; correction made under s. 13.92 (4) (b) 7., Stats., Register December 2011 No. 672; CR 11-047: am. Register May 2012 No. 677, eff. 6-1-12.

SPS 341.71 Existing vessels. Secondhand boilers and secondhand pressure vessels, originally installed in Wisconsin and not constructed and stamped according to some edition of the ASME code, may be reinstalled if the maximum allowable working pressure is recalculated with a factor of safety of 6.

Note: The pressure calculation formula for shells is as follows:

P = (T.S. x t x E)/(R x F.S.)

where P = maximum allowable working pressure, pounds per square inch

T.S. = tensile strength of shell plate, pounds per square inch

t = minimum thickness of shell plates, inches

E = efficiency of longitudinal joint

R = inside radius of the outside course of the shell, inches

F.S. = factor of safety

Note: The pressure calculation formula for flat heads and flat surfaces is as follows:

P = (T.S. x t2)/(0.5 x d2 x F.S.)

where P = maximum allowable working pressure, pounds per square inch

T.S. = tensile strength of shell plate, pounds per square inch

t = thickness of plate, inches

d = diameter of head or shortest unsupported span of head or maximum
pitch between stays, inches

F.S. = factor of safety

History: Cr. Register, February, 2000, No. 530, eff. 3-1-00.

SPS 341.72 Vessels from out-of-state. Secondhand boilers and secondhand pressure vessels, from out-of-state, shall be constructed and stamped according to some edition of the ASME code. A copy of the manufacturer’s data report shall be furnished to the department for each vessel indicating that it was manufactured originally to the requirements of an earlier edition of the applicable ASME code. If a vessel has been repaired or altered since its fabrication, a copy of the manufacturer’s data report, welded repair report or alteration report shall be furnished to the department.
