Precision Tube Price List (May 2026)

The bands below are indicative prices for orders placed in May 2026, comparing DIN 2391 cold-drawn seamless tube with IS 4923:2017 square and rectangular structural hollow sections. IS 4923 does not cover circular precision cylinder tube. You should compare the same shape and duty, then put the dimensional limits, supply condition, surface requirement, and drawing on the RFQ.

All prices are per kilogram (₹/kg), ex-warehouse Kanpur, exclusive of the legally applicable tax stated on the current quotation. For a firm delivered quote, submit your RFQ.

What Drives Precision Tube Pricing

The Right Buyers for Precision Tube in Kanpur

Precision tube is used where the drawing controls OD, wall, bore, straightness, surface condition, or subsequent honing more tightly than a general-purpose pipe order. Hydraulic-cylinder, printing-roller, pneumatic, instrumentation, automotive, and textile-machinery buyers in Panki and Dada Nagar should start from the finished part. Put supply condition, machining or honing allowance, dimensional limits, surface finish, straightness, and inspection method on the RFQ. Also state the sampling plan, measurement locations, gauge method, and whether results belong on an inspection report. Do not infer a tolerance from a generic application label.

Structural frames, sheds, and general fabrication should use IS 4923 hollow sections or IS 1239 ERW when the drawing names those products, so do not buy precision tube for that work. If the drawing or code requires an IBR boiler or steam-piping tube, do not substitute cold-drawn hydraulic stock. See application detail at precision tubes in hydraulic applications, the product range at precision tubes (product), and local supply at steel pipes in Kanpur.

Precision Tube RFQ Checklist: What Your PO Must State

Tolerance and surface finish decide acceptance on precision orders. State the items below so the quotation can be checked against the finished-part drawing.

• OD with wall thickness: exact outside diameter and wall in mm, since precision tube trades on OD.
• Standard and grade: the approved precision-tube specification, or IS 4923 square or rectangular section with the required YSt grade.
• Tolerance: governing edition, tolerance class, supply condition, and drawing limits for OD, wall, bore, straightness, and length.
• Surface and straightness: bore finish requirement (as-drawn or pre-hone) and straightness callout for long barrels.
• Honing scope: whether the RFQ is for as-drawn tube, a pre-hone allowance, or a finished-bore scope. Coordinated honing or chrome-plated rod is included only when the quotation names that work.
• Test certificate: MTC with chemistry, mechanicals, dimensional results, and heat traceability.
• Delivery basis: ex-warehouse Kanpur, tax as stated on the current quotation, freight to the named site if quoted. A cut length is included only when the quotation names that work.

Worked Example: Budgeting a 500 m Hydraulic Order

Take a 38.0 mm OD tube with a 3.0 mm wall, a staple hydraulic-barrel size. The site weight formula, (OD minus wall) times wall times 0.02466, gives (38.0 minus 3.0) times 3.0 times 0.02466, which is 2.59 kg per metre. The DIN 2391 band for this size is Rs 102 to Rs 128 per kg, so each metre costs about Rs 264 to Rs 331 ex-warehouse Kanpur before the legally applicable tax. A 500 m order weighs 1,295 kg, or about 1.29 MT.

The order budget becomes about Rs 1.32 lakh to Rs 1.66 lakh before the legally applicable tax stated on the current quotation, freight, and any honing charges. Compare that with the IS 4923 hollow-section column for nearby sizes at Rs 55 to Rs 68 per kg. The lower structural-tube band does not make it a cylinder-barrel substitute, because the product form, tolerances, condition, and acceptance plan differ. Confirm tonnage on the pipe weight calculator and the process detail at precision tube process hub.

Common Procurement Mistakes on Precision Tube Orders

• Substituting hollow sections for barrels. IS 4923 sections are structural stock. For cylinder duty, the RFQ needs the drawing-specified tube standard, condition, and acceptance plan.
• Leaving dimensional limits off the PO. State the governing edition, tolerance class, supply condition, and drawing limits so the offered tube can be checked before machining.
• Buying a tolerance label without its basis. The applicable limit changes with dimension and supply condition; compare mill offers against the same drawing and inspection method.
• Forgetting the honing step in budgets. As-drawn tube does not automatically meet a named bore class. If the drawing requires a honed finish, treat that operation as a separate quoted scope.
• Ordering small ODs late. Sizes below 20 mm OD cost more per kg and draw slower. Freeze sub-20 mm quantities early.

Standards and Compliance: DIN 2391 and IS 4923

A precision-tube order needs more than the words "cold drawn." State the governing standard and edition, steel grade, supply and heat-treatment condition, OD, wall, length, dimensional tolerances, straightness, surface condition, and test requirements. If a tolerance class is used, you must read its actual limits for the ordered dimension and condition rather than copying them from a different size. The finished-part drawing controls whether the tube can meet the machining or honing allowance.

IS 4923:2017 covers square and rectangular hollow steel sections for structural use. Current standard grades include YSt 210, 240, 310, 355, 420 and 460; the quotation must identify which required grade, size and wall are actually offered. Circular hollow sections are outside this standard, so specify the separate applicable tube standard or approved drawing for a circular requirement. Compare the two regimes at DIN 2391 vs EN 10305 and read the section tables on our IS 4923 reference.

Buying Precision Tube in Kanpur for Hydraulic and Machine Shops

From Panki, Dada Nagar, or the Bartan Bazar market area, you should name OD, wall, grade, supply condition, heat, and length on the RFQ. Where a finished bore or cut length is required, put the pre-hone allowance, finished dimension, surface requirement, quantity, and need-by date in one enquiry so the quotation can confirm offered material and any outside processing for that request.

Name the destination PIN on the RFQ if the load is intended for a site in Uttar Pradesh or a neighbouring state. Ask the formal offer to list the mill and heat, documents supplied, cutting or honing scope if quoted, vehicle and freight basis, dispatch estimate, transit basis, unloading responsibility, and validity for that request. If third-party inspection is required, state the agency and witness points before a loading date is agreed. Follow sourcing context on the Kanpur steel market page.

You can name destinations such as Lucknow, Agra, Prayagraj, Varanasi, Gorakhpur, Jhansi, Bareilly, Unnao, Kanpur Dehat, or Patna. For a delivered comparison, use the same PIN, weight, vehicle, packing, transit basis, unloading terms, and insurance basis on every offer; freight is confirmed from the current lane quote rather than a standing per-kilogram promise.
