Thank you to the author for sharing the GBT 19190-2025 standard, which is a perfect reference for those who make oil drilling equipment. The link can be opened. Is the file in PDF format? But I want to remind you, * * Although standard documents can be disseminated and studied online, if they are official publications, copyright may be involved. After downloading, try to use them only for personal research and not for commercial use. In addition, if the link has an expiration date or the extraction code is case-sensitive, remember to say "ha" so that fellow forum members who come later can download it smoothly. Having this standard to look at the equipment specifications against will save you a lot of trouble. Thank you again!
