How to protect S690QL1 steel tube from crack

"Turkey has filed a lawsuit against EU steel import tariffs with the world trade organization, the trade ministry said Friday. In February 2019, the European Union said that the sharp increase of Turkish steel imports S690QL1 steel tube seriously threatened the steel producers in member countries. The European Union has set import quotas for 26 kinds of steel products and imposed a 25% tariff on future steel products for three years. Turkey's trade ministry said that as one of the main S690QL1 steel tube steel exporting countries to the EU, Turkey's export has been adversely affected by its measures and has started proceedings in the WTO."

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."

15Mo3 heat resistant steel plate for boiler and pressure vessel executive standard: DIN1715515Mo3 heat resistant steel plate delivery status: normally delivered in normalized status. According to the special agreement at the time of ordering, 15Mo3 heat resistant steel plate also be delivered in non processed status.15Mo3 heat resistant steel plate is mainly used for steam boiler equipment, S690QL1 steel tube, pressure vessels, large pressure pipes, drum manufacturing of utility boilers and similar components.
