Prime
Quality Hot Extruded Mother Pipes are selected carefully for
each individual requirement. Preliminary testing ensures chemical
composition, metallurgical and physical properties are in
conformance with finish tube requirements.
Seamless mother pipes are deoiled, cleaned,
before annealing. Annealing is carried out prior to cold drawing.
Cold drawing of tubes is carried out by using TUNGSTEN DIES
& MANDRELS. Cold drawing reduces the cross section of
tubes by tension through die and fixed or floating mandrel
or plug. Reduction ratio of 25 - 30% in a single draw are
commonly applied.
Cold drawing is carried out several times
till the tubes are brought down to the required size. After
each cold drawing the tubes are subjected to heat treatment
straightening & surface cleaning. The finish tubes are
then subjected to extensive testing as per the requirements
of the specifications and also those of the customer's before
they are finally despatched to the customer.
Additional tests such as Eddy Current Testing, Ultrasonic
Testing, Corrosion testing, Macro &. Micro Structure Examination,
IGC etc., are carried out if required by the customer.
Every single piece is electrically Etched/ Paint marked mentioning
Manufacturer's name / Size / Specification / Heat No. / Third
Party inspector's initials (when agreed)
Popular sizes of Carbon Steel, Alloy Steel, Stainless Steel
pipes & tubes are available Ex- stock or at a short notice.
Note: Stainless Steel is solution annealed. Carbon Steel &
Alloy Steel is annealed
