Description:
 
DIN17175 seamless cold drawn steel tube (carbon steel, alloy steel), applies to seamless tubes including tubes for headers of heat-resistant steels which are used in the construction of boilers, pipe-lines, pressure vessels and equipment for service up to 600℃ and at simultaneous high pressures, where the total stress and the relevant scaling conditions can raise or lower the temperature limit.
 
 
Applications:
 
1. construction of boilers, boiler flue
2. pipe-lines 
3. pressure vessels
4. equipment for service up to 600℃ and at simultaneous high pressures, where the total stress and the       relevant scaling conditions can raise or lower the temperature limit.
5. superheater service
6. air preheating pipe line
7. superheater 
 
 
Competitive Advantage:
 
Always put quality on first consideration makes us keep our qulity stable and good. Always put customer’s benefit before ours makes our good service and gain us good reputation.
Advanced equipments. Sincere , truth and careful attitude on communication and production.
