Product Usage and Introduction

This series of products are steels for boilers and pressure vessels, used in power generation and steam boilers, heat exchangers, fixed pressure vessels, mobile pressure vessels, marine pressure vessels, petrochemical equipment, spherical tanks or storage tank bodies, etc. They also need to withstand certain internal pressures and high or low temperature environments, so the selection of materials needs to be determined according to actual conditions. Below, we will introduce to you the thickness range, delivery status and execution standards of various grades we can provide. We hope this can be helpful to you. If you have any questions about the products or need to inquire about prices, you can contact us by email. Since some grades can be classified into multiple categories according to their uses, it may cause inconvenience for you to find them, and we sincerely apologize for that. If you have any good suggestions, you can also tell us. Thank you very much!
