gpsvn ...I bow to your sharp eye! ASTM A694 is a mat'l used for fittings. I had grabbed the wrong mat'l when I looked it up. It should be ASTM A672! However API-5L is specification for mat'l to be used for pipe. The purpose of this specification is to provide standards for pipe suitable for use in conveying gas, water, and oil in both the oil and natural gas industries. This specification covers seamless and welded steel line pipe.

Hi 11echo, I did mean to hurt any one here. Sorry if I did.

It's just by chance I was dealing with API 5L Gr X60 line pipe and A694 fittings in my last project. I am not sure and I have not checked but I still think that API 5L Gr. 60 is actually a material destination, just like ASTM A694. I remember seeing its mechanical and chemical properties requirements of API 5L Gr. X60 somewhere, probably when I looked at the WPS and PQR for the job.

gpsvn ...Didn't hurt my feelings! I've been in this business too long to have my feeling hurt! *G* When your wrong your wrong, I didn't claim to NOT be human, and I’ve made my share of mistakes! …And it seems I continue to be human too! *L*
API-5L specification is a list of requirements of a pipe to meet temp.s/pressures/yield for certain commodities. AND there are a number of ASTM materials that "CAN" do this. Cost and available are contributing factors here, but the bottomline is more then one ASTM material can meet this API-5L spec. So under API-5L, ASTM A106-B could be used, but also ASTM A53-B for the same pipeline …and the mat’l spec could just say API-5L-60X. But again, under the API-5L designation, it could have multiple ASTM types to cover the API-5L spec. BUT the ASTM spec covers only one type of steel per designation. Clear as mud? *G* …Mark

Hi 11echo, my english is poor and I have difficulties in expressing myself. I'm glad that you are tolerable.

Thank you for your clarifications. Will you please elaborate a bit more for the benefits of mine and others.

I'm using the Trouvay & Cauvin "blue book". An online sample is available from here: www.tcbluebook.com/pages/prev1.php

In that book, I see no different between API and ASTM, they are both "specifications". Under each specification, there are chemical and tensile requirements.

API-5L is a piping specification, where it just lists the requirements of the pipe to carry a specific commodity under certain press/temp/yield strength, but does NOT point to any one type of steel. A number of different steels or manufacturing processes could be used. All you are assured of getting by specifying API-5L, without additional details, is a pipe meeting API-5L with a minimum yield point. It could be manufactured to SMLS, DSAW, UOE, etc. and composed of a number of different elements and compounds at various concentration quantities up to permitted limits.
