Zenith Erw Pipes

ERW Pipes Manufacturing Process

ERW pipe is formed from hot-rolled coil produced in steel mill. All the incoming coils are verified based on the test certificate received from steel mill for their chemistry and mechanical properties.

The forming stage of ERW pipe begins with a single-width strip. The width of strip is roughly equal to the perimeter of the pipe to be produced. The edges of coil are sheared to pre-specified widths in slitting line.

The process involves uncoiling & leveling of coils and processing the same. The lead end of each coil is squared by shearing operation for threading into the mill. Then this end is joined with coil end of outgoing coil to maintain continuity in production and reduce losses.

To maintain continuity of production, it is accumulated in an accumulator/loop pit. It is then gradually and continuously formed into a circular shape by shaped rolls as per the required diameter in forming stands arranged in tandem. In the welding stand, edges of formed strip are pre heated by High Frequency Electrical Induction heating process to the desired temperature, which are mechanically pressed together horizontally to form continuous weld seam. This welding process does not need any filler metal. Instead, the welding pressure causes some of the metal to be squeezed from the joint, forming a bead of metal on inside and outside of the tube. This bead or welding flash is trimmed during the process. The weld seam is examined and adjusted as per the weld parameters, including temperature and outside diameters. The weld area of the string of the pipe so welded is then annealed, as per customer's specification by induction heating process, to get fine grain structure in weld area. It is then cooled in open followed by water quenching. Subsequently pipe string passes through sizing stands to obtain perfect roundness and diameter. The pipes are non-destructively tested by Eddy Current Process to detect any flaw in weld or otherwise as per customers requirement.

During production, online visual inspection is also carried out for surface defects, diameter accuracy, ovality and weld bead shape. Required sample rings as per specification are cut to carry out mechanical testing of weld and body e.g. flattening test, bend test etc. All pipes are then processed in finishing and testing area 
for pipe end preparation i.e. Facing/Beveling followed by hydrostatic pressure testing as per specification.

Individual pipe is then visually inspected for the parameters specified in the specification before offering to the customer's inspection, if any. Data of all tests is re-verified and submitted to the customers.

BLACK PIPES - On acceptance, all pipes are marked and/or paint stenciled as per the order requirements, packed in bundles before shifting in the storage yard. Pipes are then loaded on trailers or trucks and dispatched to the customer's site. These pipes can also be supplied with black paint/oiling &/or threading.

GALVANISED PIPES - the accepted pipes are washed in solution of caustic soda tank followed by pickling by hydrochloric acid of suitable concentration to remove oxides on pipe surface & is then dipped in fluxing tank. Pipes are then preheated & dipped in molten zinc bath. Pipes are then pulled out from the bath & wiped externally & internally for uniform & smooth zinc coating. Pipes are then cooled in quenching tank followed by passivation. Pipe ends are then threaded as per specification, if any, inspected for coating & threading defects, physical dimensions & condition before stenciling & packing.
