‌ASTM A691 2-1/4Cr Grade Steel Pipe‌ is an electric fusion welded steel pipe specially designed for high temperature and high pressure conditions.

The EN10219-1 steel pipes supplied by GNEE use high-quality carbon steel as raw material and adopt longitudinal submerged arc welding process to ensure the quality of the weld and improve the overall performance of the steel pipe.

DIN 1628 ERW Carbon Steel Pipe is a type of steel pipe manufactured by the electric resistance welding process.

DIN 2394 precision steel tubes have the characteristics of high precision, high finish, good inner wall cleanliness, ability to withstand high pressure without leakage, no deformation when cold-bent, and no cracks when expanded or flattened.

ASTM A53 Grade B ERW Pipe is a carbon steel pipe that comes under the ASTM A53 specification. The pipes range in dimensions according to the ASTM, ASME and API standards.

DIN 2393 standard is applicable to welded precision steel tubes with special dimensional accuracy. These steel tubes are mainly used in occasions with high dimensional accuracy requirements.

ASTM A214 Boiler Tube is a type of electric resistance welded boiler tube produced in accordance with ASTM A214 standard. This type of tube is mainly used in boilers, heat exchangers and other similar high temperature applications.

EN10217-2 P235GH Welded Steel Pipe is a specific type of steel pipe, which complies with EN 10217-2 standard and has the steel grade of P235GH. This steel pipe is mainly used for pressure welding applications in high temperature environments.

S235JRH grade belongs to standard EN10219. EN10219 S235JRH welded steel pipe is a carbon structural steel, JR means its impact properties are at room temperature.

ASTM A572 GR.42 welded pipe has high strength and good toughness. It is widely used in various structural projects that require welded steel pipes.

ASTM A252 is a standard specification developed by ASTM International for welded and seamless steel piling pipes. These pipes are mainly used for deep foundations to support buildings, bridges and other structures.

EN S355J2H structural round steel pipe is a structural seamless steel pipe that complies with European standards (EN 10210 or EN 10219). Its material is S355J2H.
