A leading manufacturer, exporter, suppliers & stock holder of Tube & we provide a comprehensive range of Tube.
We manufacture Tube in India for export all around the world.
Tube
Ovality of steel tubes
(out of roundness), is the difference between max. and min. diameters readings taken in the same given section. Ovality shall be within OD tolerance.
O = ODmax – ODmin (absolute value in mm)
O = 100.(ODmax – ODmin) / OD (in %)
Marking system for steel pipes according to EN
EN 10027 – 1 system of reduced marking, the basic symbols.
EN ECISS IC10 additional symbols.
EN 10027 – 2 system of numerical marking.
Types of Tubes:
Packaging of steel tubes and pipes
Packaging rolled seamless tubes
Bundle of circular cross section with a diameter of max. 800 mm, max. weight of 3500 kg. Upon agreement bundle with hexagonal cross-section.
Standard ways:
Bundle tied by wire
Bundle tied by a steel tape
Steel tape underlined by tapaten
Upgraded packaging:
The ends of the tubes (bundles) are wrapped in PE film or a film and tapaten
After agreement protection of the inner surface of tubes by plastic caps.
Types of tests and documentation
By testing the proving is done which proves that the properties of tubes are identical to the requirements of the order and the relevant standards.
The process is divided into three parts:
- Determine the type of test (EN 10021, EN 10204)
- Determine the type of inspection document (EN 10204)
- Selection of individual tests (specifically TDP)
