EN 10216-2 seamless steel tube for high temperature and high pressure purpose
1. Product Description
En10216-2 is a seamless steel pipe for high temperature and high pressure. Its products are widely used in boilers, heating pipes, superheaters, reheaters, pressure vessels and instruments.
The main materials are p195gh, p235gh and P265GH. They have different inspection requirements, chemical composition and mechanical properties. Customers can choose their own products according to their own needs. Please refer to the table below for specific chemical composition and physical properties.
According to the internal regulations of CEN / CENELEC, the following countries are using this standard: Austria Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, the United Kingdom, after years of efforts, our customers have been sold to the above countries, product quality and service, their trust and praise.
The EN10216-2 standard seamless steel pipe for export can be painted and marked on the surface, chamfered, threaded at both ends, and blunt. The two ends of the steel pipe can be provided with pipe caps and protective covers. Various export packaging methods can ensure the safe transportation of products.
