When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials normalized NV E32 hull steel plate. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
SA299GrB steel plates with a thickness of less than or equal to 50mm are usually delivered in the rolled state, and can also be delivered in the state of normalizing, stress relief, or normalizing plus stress relief. Steel plates with a thickness greater than 50mm should be normalized heat treatment. It can also add flaw detection standard requirements, flaw detection level requirements, alloy element composition control requirements, etc. according to needs.
The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for normalized NV E32 hull steel plate pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common normalized NV E32 hull steel plate carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.

Due to the surge in business volume in recent years. In addition to coordinating our own truck fleet, our logistics department has continuously developed high-quality logistics companies and signed long-term cooperation agreements. While enjoying the professional and fast service of logistics companies, we have significantly reduced transportation costs. That not only ensure our customers receive the goods at the same time, but also help them reduce shipping costs.
Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to normalized NV E32 hull steel plate customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied. If you have any requirements and needs, please contact us in time.
