1.0 PURPOSE:
To describe a standard operating procedure for numbering of equipments.
2.0 SCOPE:
The standard operating procedure describes in detail the method of numbering of equipments. The equipment include reactors, receivers, addition vessels, condensors, nutsch filters, pressure filters, air ovens, centrifuges, sifters, blenders, micronizers, chariots, solvent lifting pumps, utility pumps, leaf filters, millers, chilled water compressors, brine compressors, air compressors, DM water plants, softners, boilers, DG sets, transformers, distilled water plants, solvent recovery columns, vacuum pumps, blowers, exhaust fans, cooling towers, air handling systems, fluid bed driers, air exhaust systems, storage tanks, line filters, micron filters, purified water systems, vacuum dryer, air conditioners and compressed air dryers.
3.0 RESPONSIBILITY:
The responsibility of numbering of equipments as per the standard operating procedure lies with staff of rank not lower than the Maintenance engineers.
The responsibility of preparing, reviewing and approving the standard operating procedure lies with the Manager - Maintenance, Head of Production and Head of QAD respectively.
4.0 METHOD:
4.1 For reactors, numbering starts with 1100 and proceeds with the increments of 100 till all the reactors are completed. The reactors in Block-I & II shall have the prefix 'S' while those in other Blocks shall have the prefix 'C'.
4.2 Addition vessels and receivers connected to the reactor shall have the same number as that of the reactor with suffix "A" and "B" respectively.
4.3
If one or more receivers are connected to the same reactor they shall be given the same number as that of reactor with suffix B1, B2, B3 ...... (Example : S3200B1, S3200B2, .......). If one or more addition vessels are connected to the same reactor they shall be given the same number as that of reactor with suffix A, A1, A2, .... . (Example : S3800A, S3800A1, S3800A2, ....).
4.4 If two or more reactors have common addition vessel, the addition vessel shall be given the lowest number of the reactors with suffix 'A'.
(Ex: S3200 and S3300 connected with common addition vessel, the number of addition vessel shall be S3200A)
4.5 If two or more reactors have one or more common addition vessels, the addition vessels shall be given the lowest number of the reactors with suffix A, A1, A2...... (Ex: S3400 and S3500 connected with two or more addition vessels, the number of addition vessels shall be S3400A, S3400A1, S3400A2 etc.)
4.6 If two are more reactors have common receiver the receiver shall be given the lowest number of the reactors with suffix ‘B’
(Ex: S3100 and S3200 connected with a common receiver the number of receiver shall be S3100B.)
4.7 If two or more reactors have one or more common receivers, the receiver shall be given the lowest number of reactors with suffix 'B1','B2','B3'...... .
(Ex: S3200 and S3300 connected with two or more common receivers the numbers of receivers shall be S3200B1, S3200B2, S3200B3,…..)
4.8 The condensors connected to the reactor shall have the same number as that of the reactor with suffix ‘C’.
4.9 If more than one condensors are connected to the same reactor they shall be given same number as that of reactor with suffix 'C1', 'C2', 'C3'…..
(Example: S3200C1, S3200C2….)
4.10 The nutsch filters, pressure filters, air ovens, centrifuges, sifters, blenders, micronizers, chariots, solvent lifting pumps, utility pumps, leaf filters, millers, chilled water compressors, brine compressors, air compressors, DM water plants, softners, boilers, DG sets, transformers, distilled water plants,
solvent recovery columns, vacuum pumps, blowers, exhaust fans, cooling towers, air handling systems, fluid bed driers, air exhaust systems, storage tanks, line filters, micron filters, purified water systems, vacuum dryer, air conditioners, compressed air dryers and scrubbing systems are given the numbers
4.11 If any equipment is replaced, a new number shall be given to the new equipment. If the equipment is shifted to another location, the equipment shall have its own number in the new location also.
5.0 RECORDING:
The responsibility of preparing equipment list lies with the staff of rank not lower than the Maintenance Engineer as shown in annexure-I.
