USING API 5L IN PIPING

[QA/QC]

HELLO MASTERS 

N  OUR PROJECT ZE USE A106 IN PIPING BUT E HAVE ONLY API 5L GR IN OUR STOCK CAN WE USE IT IN PLACE OF A106 

[Jamie Reyes]

What is the exact grade?

Is the API 5L GR. (?) Smls. or Welded pipe?

Your gonna need Seamless. Need to know the Grade to determine if material is equivalent or better in mechanical properties, in comparison to A106 Gr. (?) possibly "B"???

You can use it, pl check the mechanical properties and match it to API 5L. But using TMCP Material will turn out to be a costlier affair for your project. Electrodes also should be selected accordingly.

Please go with product specification level PSL2 . This is also killed as A 106.

Dear, 

It depends on lot of factors as below.

1. Cost Consideration

You plan to replace a short length of  Pipe or a long line of Pipe.

2. Applicable Code

Considering it as Piping I presume it is ASME B31.3

3. Actual Grade of Material and the Replaceable Grade.

ASTM A 106 comes in 3 grades A,B,C and the commonly used one A 106 Gr.B and the Replaceable API 5L Grade comes in various grades and as an Example Take API 5l Gr.B

4. Application

ASTM A 106 grades are normally used in High Temperatures and hence operating temperature and Design temperature to be known.

5. Applicable Code suitability

ASME B31.3 Appendix A provides Allowable stress values which need to be compared for RT and design temperature for both the Grades.

6. Design Approval

If the allowable stress values are different and you need to calculate the minimum or nominal thickness at the applicable design temperature or take the help of a piping designer.

7. Welding suitability

After selection of Replaceable grade check whether applicable WPS/ PQR is suitable or you need to qualify new one.

Example : Suppose you are replacing ASTM A 106 Gr.B with replaceable material API 5L Gr.B  please find below the stress values from ASME B 31.3/

From the above Table it is clearly evident that ASTM A 106 Gr.B may be replaced by API 5L Gr.B/

last, API 5L materials comes in various Heat Treatment conditions and select the correct one.

Thanks & Regards

A106 is for High temp service with high carbon.

Hi Mr. Jayakumar,

Just adding few clarifications to your detailed explanations.

Thanks for sharing the information.

ASTM A 106 comes in 3 grades A,B,C and the commonly used one A 106 Gr.B and the Replaceable API 5L Grade comes in various grades and as an Example Take API 5l Gr.B

   API 5L Gr.B has equivalent strength to A 106 Gr.B 

4. Application

ASTM A 106 grades are normally used in High Temperatures and hence operating temperature and Design temperature to be known.

   Both can be used for high temperature service. Note no. 57 for Table A-1, A-1 M ( at page number 194 of ASME B 31.3-2016) is applicable for both the materials. 

5. Applicable Code suitability

ASME B31.3 Appendix A provides Allowable stress values which need to be compared for RT and design temperature for both the Grades.

Allowable stress for A 106 Gr. B and API 5L Gr. B is the same for both RT and at design temp. 

6. Design Approval

If the allowable stress values are different and you need to calculate the minimum or nominal thickness at the applicable design temperature or take the help of a piping designer.

7. Welding suitability

After selection of Replaceable grade check whether applicable WPS/ PQR is suitable or you need to qualify new one.

Both the materials falls under same P.No and G. No as per UW-422 of ASME IX.
