Leading Manufacturer, Supplier & Retailer of COLD DRAWN STAINLESS STEEL Tubes, Alloy Tubes, U Tubes, Stainless Steel Welded Tubes and Cold Drawn Stainless Steel Tube.

COLD DRAWN STAINLESS STEEL Tubes

  • Thickness 0.5 mm to 25 mm
  • OD 4mm to 220 mm

HMTL has a dedicated plant of 27, 500 sq. meter of covered area for manufacturing cold drawn of Stainless Steel Seamless & Welded Tubes/pipes with 15 pilger mills, bright annealing furnace, 5 draw benches, 3 tube mills etc. Cold finished Tubes/Pipes are produced out of quality seamless hollows which are manufactured in house in unit-III. Seamless hollows are either cold pilgered over pilger mills or cold drawn over draw benches using precision tooling (dies & plugs) to achieve perfect dimensions and smooth surfaces. Pilgered / Drawn tubes are subjected to heat treatment, straightening and surface treatment. Finished tubes/pipes undergo various testing as per the specification /customer's requirements followed by marking and packing.

Alloy Tubes

  • Thickness 3.2 mm to 25 mm
  • OD 26.67mm to 168.3 mm

The Hot finish Seamless Carbon Steel & Alloy Steel Division is equipped with latest machineries and all processes are fully automatic with on line Ultrasonic & Eddy current testing & latest testing facilities for Chemical & Mechanical testing to meet the customer requirements. MANUFACTURING PROCESS : Total Quality Management (TQM) is the key to HMTL phenomenal success. All the stage of manufacturing are thoroughly planned, closely monitored and professionally executed to meet the requirements of clients and various third party inspection agencies. We believe the only way to guarantee quality is to stand responsible for the entire process. For this reason, the steel used for the manufacture of Tubes/Pipes is chosen and prepared carefully to ensure the highest standards of quality. All round bars heat are fully killed before continuous casting into billets. The round steel bars are first heated to 1, 150º to 1, 250º C in a rotary hearth furnace. After heating, these billets pass through a cross-roll piercing mill where a carefully positioned piercing point drives a hole through the solid bars to produce elongated rough hollow blooms. These hollow blooms are then passed thru Accu Roll Mill to achieve required dimension. Then the pipes is passed through Reheating furnace at 900º C to 950º C and later to get the desired dimensions of pipe are passed by 24 frames Stretch Reducing mill. After this process pipes undergo Finishing process followed by on line NDT Testing, Varnishing and Marking as per the requirement of customer. It’s a Fully automated online plant from bar loading to packing and dispatch of finish tubes. There is no human contact with materials at any stage of process. The company gives immense importance to high ethical values in business and believes in healthy long term partnership with customers, suppliers and workers. On time consistent good quality products is supply now taken as granted from HMTL by its customers. Ensuring 100% customer satisfaction is always at the heart of everything that company does and nothing less then will be accepted by the Management.

U Tubes

Latest type of "U" bending machine is used for precision cold bending of tubes. Specifically prepared jigs and fixtures are used to ensure three dimensional accuracy for “U” bend tubes. Bending is done for all kind heat exchanges, condenser, economizer , boiler tubes in carbon steel, alloy steel and stainless steel seamless as well as welded. HT of bent portion is carried out. AT HMTL Tubes Can Be "U" Bent Up To R=1 Dia. ( Subject To Size) : Subsequent to “U” bending tubes are hydro tested and stress relieved if asked for. Also mock-up pieces are prepared for determining thickness reduction on the bend portion is done to detect cracks, flaws or any type of defects. Special packing is provided to prevent any damage during transit. Stress Relieving Of Carbon Steel And Alloy Steel ”U” Tubes "U" bent portion + 300mm on each leg length are annealed (Stress Relieved) in a batch type furnace in which temperature is closely monitored, controlled and recorded. Rate of Cooling can be controlled as per heat treatment cycle given by customer.. Heat Treatment Of Stainless Steel “U” Tubes “U” bent portion + 300mm on each leg length are heated at 1050 C temperature by transformer. The temperature is measured by an Optical Pyrometer. Cooling is done immediately by blowing cold air to avoid carbide precipitation.

Stainless Steel Welded Tubes

Stainless welded tubespipes are produced out of prime quality stainless steel strips procured from reputed approved vendors. Strips are converted into tubular form over continuous tube mill & edges are welded using tungsten inert gas (TIG) welding technique. Inside weld bead is removed with bead scarfing equipment fitted on the mill. Welded tubespipes are subjected to solution annealing, straightening and pickling operations. Finished tubespipe undergo various testing as per the specificationcustomer's requirements followed by marking and packing.
