2、NOTESAPI publications necessarily address problems of a general nature. With respect to partic-ular circumstances, local, state, and federal laws and regulations should be reviewed.API is not undertaking to meet the duties of employers, manufacturers, or suppliers towarn and properly train and equip

3、 their employees, and others exposed, concerning healthand safety risks and precautions, nor undertaking their obligations under local, state, or fed-eral laws.Information concerning safety and health risks and proper precautions with respect to par-ticular materials and conditions should be obtaine

4、d from the employer, the manufacturer orsupplier of that material, or the material safety data sheet.Nothing contained in any API publication is to be construed as granting any right, byimplication or otherwise, for the manufacture, sale, or use of any method, apparatus, or prod-uct covered by lette

5、rs patent. Neither should anything contained in the publication be con-strued as insuring anyone against liability for infringement of letters patent.Generally, API standards are reviewed and revised, reaffirmed, or withdrawn at least everyfive years. Sometimes a one-time extension of up to two year

6、s will be added to this reviewcycle. This publication will no longer be in effect five years after its publication date as anoperative API standard or, where an extension has been granted, upon republication.

14、ctice shall be cause for rejection of casing or tubingprovided the threads are in accordance with the requirements of the latest edition of APIStandard 5B.This recommended practice is presented as a guide and instructional tool for pipe millinspectors, third party inspectors, and users interested in

15、 developing skills in inspection ofthreads on oil country tubular goods and line pipe. It includes pictures of numerous gaugesand measuring instruments. Every effort has been made to present gauges without regard tothe origin of manufacture. Additionally, inclusion of certain gauges should not be co

16、nstruedas an endorsement of the instrument or its manufacture. Similarly, the exclusion of anygauge is not an indication of dissatisfaction with that instrument.API publications may be used by anyone desiring to do so. Every effort has been made bythe Institute to assure the accuracy and reliability

17、 of the data contained in them; however, theInstitute makes no representation, warranty, or guarantee in connection with this publicationand hereby expressly disclaims any liability or responsibility for loss or damage resultingfrom its use or for the violation of any federal, state, or municipal re
