Technical Inquiry – API-570/07-01

Publication Type:  API  

Publication Number:

 API 570 

Edition:  3rd, Nov 2009 

Addendum/Errata:   

Number:   

Section Referenced:

6.3.3 

Subject: Corrosion Monitoring Intervals & RBI 

Background:

Throughout the 570 code, there is language to support interval adjustments when using RBI. However, it is not absolutely clear if we must still abide by 1/2 life and/or retirement date calculation results when using RBI. Section 6.3.3 states; "If RBI is NOT being used, the interval between piping inspections shall be established and maintained using the following criteria:" It then lists corrosion rate and remaining life calculations as the first item, suggesting that it need NOT be considered.

Question:When using RBI, is acceptable to set intervals for corrosion monitoring activities and not use 1/2 life and/or retirement date calculations?

Title: Alteration of Verbiage Around Inspection Intervals

Date: May 16, 2011

Contact: Name: Ryan Sitton

Company: PinnacleAIS

Phone: 281-598-1330

E-mail: ryan.sitton@pinnacleais.com

Purpose: Improve verbiage to be more clear around requirements for UT intervals related to use of RBI.

Source: Generated from Codes Task Group, Scorecard item 570-068

Revision: 0

Rationale: The current structure of section 6.3.2 and 6.3.3 around intervals for inspection is not completely clear.

Notes: The following is the applicable sections from API 570, with tracked proposed changes.

6.3.2 RBI for Inspection PlanningScheduling Inspections

An RBI assessment may be used to increase or decrease the inspection limits described in Table 2. Similarly, the extent of inspection may be increased or decreased beyond the targets in Table 3, by an RBI assessment. When used to increase inspection interval limits or the extent of inspection, RBI assessments shall be conducted at intervals not to exceed the respective limits in Table 2, or more often if warranted by process, equipment, or consequence changes. These RBI assessments shall be reviewed and approved by a piping engineer and authorized piping inspector at intervals not to exceed the respective limits in Table 2, or more often if warranted by process, equipment, or consequence changes.

The owner/user or the inspector shall establish schedule for inspection activities such as thickness measurements and external visual inspections and, where applicable, for internal and supplemental inspections. The interval between inspections shall be based on a standard set of rules for inspection intervals or utilizing RBI. This interval shall be reviewed and adjusted as necessary after each inspection or significant change in operating conditions. General corrosion, localized corrosion, pitting, environmental cracking, and other applicable forms of deterioration mentioned in Section 5 shall be considered when establishing the various inspection intervals.

6.3.32.1 Inspection IntervalsRule Based Inspection Scheduling

If RBI is not being used When the inspections are based on a set of rules, the interval between piping inspections shall be established and maintained using the following criteria:

a) corrosion rate and remaining life calculations;

b) piping service classification (see 6.3.4);

c) applicable jurisdictional requirements;

- 4 -

d) judgment of the inspector, the piping engineer, the piping engineer supervisor, or a materials specialist, based on operating conditions, previous inspection history, current inspection results, and conditions that may warrant supplemental inspections covered in 5.5.6.

The owner/user or the inspector shall establish inspection intervals for thickness measurements and external visual inspections and, where applicable, for internal and supplemental inspections.

Thickness measurements should be scheduled at intervals that do not exceed the lesser of one half the remaining life determined from corrosion rates indicated in 7.1.1.1 or the maximum intervals recommended in Table 2. Shorter intervals may be appropriate under certain circumstances. Prior to using Table 2, corrosion rates shall be calculated in accordance with 7.1.1.1.

Table 2 contains recommended maximum inspection intervals for Classes 1, 2 and 3 of piping services described in 6.3.4, as well as recommended intervals for injection points and S/A interfaces. Maximum intervals for Class 4 piping are left to the determination of the owner/user depending upon reliability and business needs.

The inspection interval shall be reviewed and adjusted as necessary after each inspection or significant change in operating conditions. General corrosion, localized corrosion, pitting, environmental cracking, and other applicable forms of deterioration mentioned in Section 5 shall be considered when establishing the various inspection intervals.

6.3.2.2 Inspection Scheduling Based on RBI

An RBI assessment may be used to establish the appropriate timing of inspections, and increase or decrease the inspection limits described in Table 2. Similarly, the extent of inspection may be increased or decreased beyond the targets in Table 3, by an RBI assessment. When used to increase inspection interval limits or the extent of inspection, RBI assessments shall be conducted at intervals not to exceed the respective limits in Table 2, or more often if warranted by process, equipment, or consequence changes. These RBI assessments shall be reviewed and approved by a piping engineer and authorized piping inspector at intervals not to exceed the respective limits in Table 2, or more often if warranted by process, equipment, or consequence changes.

Ballot 570-xx-xx

Title: PWHT Definition

Date: May 17, 2011

Contact: Name: John Harville

Company: BP

Phone: (219) 473-3515

E-mail: john.harville@bp.com

Purpose: Simplify definition for PWHT

Source: Scorecard item 570-066

Revision: 0

Rationale: Simplify definition for PWHT to: Post Weld Heat Treatment. Refer to ASME B31.3, section 300.2, "heat treatment".

Notes:

Current definition in API 570:

3.1.69postweld heat treatmentPWHTTreatment which consists of heating an entire weldment or piece of fabricated piping to an elevated temperature after completion of welding in order to relieve the detrimental effects of welding heat, such as reduce residual stresses, reduce hardness, and/or slightly modify properties See ASME B31.3 paragraph 331.

Proposed wording for the definition of PWHT, which is basically a cut/paste from B31.3, 300.2, Heat Treatment (g):

3.1.69postweld heat treatmentPWHTUniform heating of a structure or portion thereof to a sufficient temperature to relieve the major portion of the residual stresses, followed by uniform cooling slowly enough to minimize development of new residual stresses.

Ballot 570-xx-xx

Title: External Visual Inspection Personnel

Date: November 10, 2011

Contact: Name: Mark Smith

Company: MSTS

Phone: (918) 531-2441

E-mail: mark-msts@peoplepc.com

Purpose: Use of qualified NDE examiners to perform external inspection

Source: New

Revision: 0

Rationale: Per Section 5.5.4, External Inspection should be conducted by the inspector or qualified operating and maintenance personnel. Why not add a qualified NDE examiner? Often the Thickness and External inspections are due at the same time. It would be more cost-effective if both activities could be conducted at the same time by the same qualified individual. It would also provide good training for NDE personnel who will be moving to Inspection positions.

Notes:

5.5.4 External Visual Inspection

…

(5th paragraph):

The periodic external inspection called for in 6.4 should normally be conducted by the inspector, who also shall be responsible for recordkeeping and repair inspection. Other Qqualified operating or maintenance personnel also may conduct external inspections, when acceptable to the inspector. In such cases, the persons conducting external piping inspections in accordance with API 570 shall be qualified through an appropriate amount of training.

Ballot 570-11-04

Title: Pipeline Piping

Date: November 10, 2011

Contact: Name: Mark Smith

Company: MSTS

Phone: (918) 531-2441

E-mail: mark-msts@peoplepc.com

Purpose: Clarify whether pipelines are covered by API 570

Source: New

Revision: 0

Rationale: API 570 does not seem to cover pipelines under regulations of Department of Transportation (DOT). But whether pipelines are covered or not is not clearly stated in 570. Suggest adding a sentence in Section 1.1.1 to clarify.

Notes:

1.1.1 Coverage

API 570 covers inspection, rating, repair, and alteration procedures for metallic and fiberglass reinforced plastic (FRP) piping systems and their associated pressure relieving devices that have been placed inservice.

API 570 does not cover pipelines under regulations of Department of Transportation (DOT).
