Inspection and TestingInspection and Testing

  1. Purpose: This procedure describes the stages at which inspections and tests of the product are carried out to ensure its conformance to the application purpose specification.
  2. Scope: This procedure applies to all products with the exception of those listed in the Schedule (EXH-2D) to Procedure QP-PRO02.
  3. Procedure With the benefit of PT, XT, ET, UT, HT, HPT, PGT, LT, ST, (see definitions pt1-pg25) the company controls its processes, see work instructions to be found in this manual pt3.
    • In-process Inspection
      1. The Materials Controller examines manufactured components before they are incorporated into final assemblies. See EXH 17-B, 17-C 2pages.
      2. He checks dimensions, surface finish (either visually or by Electro-formed Surface Roughness Comparison Standard) and any other criteria as specified on the PREVENTOR or component Drawing.
      3. If he finds nonconforming parts, he withdraws them from production to the quarantine area, and informs the Chief Engineer, by means of a CAR (Procedure 20), in order that appropriate action may be taken.
      4. If the parts conform to requirements, the Materials Controller authorizes their incorporation into the assembly and verifies his inspection on the Inspection Certificate (see Exhibit EXH-17A).

Pressure Testing

Pressure testing is carried out by operators of all final products in accordance with ASME VIII  UG 99, UG 100, & UG 101, these are conducted by use of the test rig with chart recorder (up to 10,000psi) , or as specifies by contract.

Numerous proven used instructions are available for the client to choose from.  These are kept in H:\-\rpw\q\Prestest .The work order states in the "construction and certification" section, whether any of these are to apply in place of or in addition to those specific requirements of ASME for unfired pressure vessels (above) .

Should any vessel or pipe fail to maintain pressure by leakage the test item is set aside, clearly marked (by means of a large "X" on it in yellow marker) as nonconforming where necessary, and the Chief Engineer is informed, again by means of a CAR, in order that appropriate action may be taken (Pro 20).
