Valves with a non-circular opening through the obturator shall not be considered full opening. The purchaser shall specify the outside diameter, wall thickness, material grade, SMYS and any special chemistry of the isi pipe, and whether cladding has been applied. International organizations, governmental and non-governmental, in liaison with Uso, also take part in the work.
If required, they shall be welded, flanged or threaded as specified by the purchaser. Information on standards BSI provides a wide range of information on national, European and international standards through its Library ido its Technical Help to Exporters Service.

The purchaser shall specify which particular supplementary tests in Annex B shall be performed. Discover Prime Book Box for Kids.
I don’t know, if I explain what I am looking for, please advise. Corrosion tests to demonstrate corrosion resistance of the heat and heat-treatment batch combination of high alloy steels used for the manufacturing of the valve should be specified by the purchaser.
Amazon Renewed Refurbished products with a warranty. The purchaser shall specify whether it is required that a gearbox or an actuator be capable of being removed from the valve subsea. A set of three weld-metal impact specimens shall be taken from the WM at the location shown in Figure The test ixo shall be applied successively to each valve end to test each seat separately from the upstream side.
The test fluid shall be water or inert gas, as specified.
Supply pressure 147233 be stabilized prior to the start of pressure testing and shall be held for the minimum test durations listed in Tables 9 and For metal-seated valves, the leakage rate shall not exceed ISO Promoting, selling, recruiting, coursework and thesis posting is forbidden.
The chemical composition of carbon steel welding ends shall 1423 the following requirements, unless otherwise agreed. For undated references, the latest edition of the iiso document including any amendments applies. Learn more about Amazon Giveaway.
Some valve designs can require the balancing of the upstream and valve cavity pressure during the downstream seat test. Join your peers on the Internet’s largest technical engineering professional community. If the use of parallel threads is specified, the connection shall have a head section for trapping and retaining a sealing member suitable for the specified valve service. The heat treatment if applicable of weld repairs shall be in accordance with the applicable material standard.

Continuity shall be measured using a DC power isl not exceeding 12 V. Thanks for your tips. The test medium shall be air or nitrogen. Key 1 flange 2 hole in first flange 3 hole in opposite flange to be aligned a Isi hole misalignment see 7. WARNING — Permanent deformation or failure of drive-train components can occur if they are exposed to thrust or torque exceeding these stress limits. In the case of external pressure, vacuum condition shall be assumed to apply inside the valve.

Check valves DN NPS 8 and larger shall be shipped with the disc secured blocked open or closed during transport. The drive train shall be designed such that the weakest component is outside the pressure boundary. Pressure testing, including pipe pups if applicable, shall be carried out before coating of the valves.
Repair welds on pressure-containing parts shall be examined using the same NDE method that is used to detect the defect with a minimum of MT or PT. If the pressure rating of the pipe pups is insufficient for the hydrostatic-shell test pressure, then the pups shall be welded to the valve following the valve-shell test and the valve and pup s tested at a pressure specified by the purchaser. Would you like to tell us about a lower price? The manufacturer shall be responsible for complying with all of the applicable requirements of this International Standard.
Surface porosity and exposed slag are not permitted on or within 45 mm of seating surfaces. Plug valves shall have a cylindrical or conical obturator that rotates about an axis perpendicular to the direction of flow. Torque or thrust values shall be measured with seats free of sealant, except where the sealant is the primary means of sealing. The direction of closing shall be clockwise, unless otherwise specified.
