DIN EN 10268

DIN EN 10268 flanges, Pipe Fitting, Steel Pipe, Heat Exchanger and Reducer, Gasket, Tee, Pipe Fitting, Tube Plate, have all specifications. With many yeas production experience, strict control ASTM 11Q chemical composition and ASTM 11Q mechanical properties.

Production specification
Data center describes many of the common steel models, we can not determine the company's warehouse has all types of steel products inventory or raw materials.

Angle bar: 1mm to 1300mm
Steel Pipe: 1 - 1300mm, also can be customed.
Pipe fitting Size: 1/8 inch - 80 inch (DN6 - DN2000)
Flange Size: DN6 - DN2000
Lenth: Any lenth based on the customer's requirement.

In doubt the technical standards apply.
