Characterised by excellent weldability, and excellent formability ensuring ease of bending and flaring.
NB. Tubes can be bent (U shaped) to a radius of 2.5 x outside diameter minimum.The normalising is carried out at 925 oC in a controlled atmosphere furnace resulting in a bright finish.
All tubes are square cut into fixed lengths; imperial diameters to 6.096 metres (20 foot), and metric diameters into 6.000 metre lengths. Ends are deburred internally and externally, and fitted with plastic end caps to stop entry into the bore of any foreign matter. The ID and OD are lightly oiled.
Feedline tube is used extensively by the hydraulic and pneumatic industries, and is also employed by other industry sectors for a wide range of applications.
Typical applications are: Agricultural Equipment, Food Processing Equipment, Mining and other Earth Moving Equipment, Transport and Waste Disposal Equipment etc.
MachiningFeedline tubes are readily machineable due to the cold drawn and normalised structure. All operations may be carried out satisfactorily as per machine manufacturers recommendations for suitable tool type - feeds and speeds.
WeldingFeedline tubes have excellent weldability due to their low carbon content, and can be readily welded by all of the standard welding procedures.
Welding ProcedureA pre-heat or post-heat is not generally required. Low carbon electrodes, similar to the parent metal are recommended. please consult your welding consumables supplier for suitable electrodes etc.
Third Party inspection acceptable. such as SGS, BV etc.Supplying financial support with usance L/C 180days after B/L date.
