Buyers ordering MS, CS and SS pipe fittings in Kanpur land at our Bartan Bazar yard for a single reason: fittings sit next to the pipe they connect to. Most of our customers order pipe and the matching elbows, tees and reducers in one BOQ — getting both from the same supplier shaves a working day off the procurement cycle and removes the schedule-mismatch risk that bites when a 4" Sch 40 pipe arrives next to a 4" Sch 80 elbow from a different vendor. Stocked range covers IS 1239 Part 2 threaded fittings and ASME B16.9 butt-weld fittings in 1/2" through 12" NPS, with larger sizes and alloy grades mill-routed against order.
Pipe fittings stocked in Kanpur — categories and sizes
The Kanpur fittings market splits cleanly into two: the threaded plumbing trade that runs alongside IS 1239 GI and ERW pipe, and the butt-weld process-piping trade that runs alongside seamless and heavier-wall ERW. We stock both. The categories below cover roughly 90% of what a typical Kanpur or eastern-UP buyer asks for in a given quarter.
90° and 45° elbows (LR / SR)
Long-radius (LR, R = 1.5D) and short-radius (SR, R = 1.0D) elbows in 1/2" through 24" NPS. LR is the default for process piping where pressure-drop matters; SR for tight-space plumbing and structural runs. Schedule 40, 80 and XS commonly stocked; XXS and Sch 160 on order.
Equal and reducing tees
Branch tees for split-flow and header-takeoff work. Equal tees in the same-NPS configurations from 1/2" to 24"; reducing tees for the typical step-downs (2x1, 2x1.5, 3x2, 4x3, 6x4, etc.). ASTM A234 WPB carbon and A403 WP304/316 stainless to ASME B16.9.
Concentric and eccentric reducers
Concentric reducers for vertical runs and pump-suction work where the centreline stays aligned; eccentric reducers for horizontal liquid lines where you need a flat-on-top profile to avoid air pockets at the reducer. Pulled-from-pipe (PFP) and hot-formed both available.
End-caps, couplings and unions
End-caps for line-end closure and pressure testing; full and half couplings for branch-takeoff and instrument tap-in service; threaded unions for maintenance-access points where a flange would be excessive. Forged in A105, A182 F304/316 per ASME B16.11 for the forged side; B16.9 for the butt-weld side.
Stub ends and lap joint flanges
Stub ends paired with lap-joint flanges for service applications that need clean disassembly without breaking the welded joint. Common in jacketed-line work and in stainless service where flange-grade stainless is a cost lever.
Cross fittings and special transitions
Four-way crosses for distribution headers; threaded-to-buttweld transitions; SS to CS dissimilar-metal transitions when the buyer specifies them. These are not always rack stock — typically one-to-two-week lead with confirmed mill source.
Standards we supply to
The standards stack is shorter than the pipe side because fittings dimensions are set by ASME B16.x and IS 1239 Part 2 with material specs coming in from ASTM. The four below cover nearly every Kanpur enquiry that lands at our yard.
- IS 1239 Part 2 — companion to the IS 1239 Part 1 pipe standard. Governs malleable iron and MS threaded fittings (elbows, tees, sockets, unions, plugs, bushes) for water-supply and low-pressure service. ISI marking and BIS licence number on the MTC are routine.
- ASME B16.9 — factory-made wrought butt-weld fittings for process piping. Sets the elbow radii, tee branch geometry, reducer length, wall thickness and end-prep bevel. The default standard for any pressure-piping fitting in the Indian process industry.
- ASME B16.11 — forged steel fittings (socket- weld and threaded). Couplings, half-couplings, plugs, caps and unions in A105 carbon and A182 F304/F316 stainless. Pressure-class 2000#, 3000#, 6000# and 9000# rated.
- ASTM A234 WPB / A403 WP304/316 — the material specs that sit underneath B16.9 dimensions. WPB for carbon steel; WP304, WP304L, WP316, WP316L for the stainless side. Read the EN 10204 3.1 vs 3.2 note for what the MTC needs to show.
Who orders fittings from our Kanpur yard
Four buyer profiles dominate. Recognising which one a quote falls into is what shapes how the BOQ is read — process fabricators care about end-prep, plumbing contractors care about ISI marking, and PWD-tendered work cares about both plus documentation depth.
Process plant fabricators
Distillery, chemical, sugar-mill and food-processing fabricators across the Kanpur–Lucknow–Unnao belt. Need full ASME B16.9 dimensional compliance, A234 WPB or A403 WP304/316 material, MTC per heat and end-bevel matched to the connecting pipe schedule.
Plumbing and building services contractors
High-rise residential, commercial and institutional projects across Kanpur. Volume mix is BSP-threaded MS fittings for water-supply risers, plus malleable iron fittings for fire-line standpipes. ISI marking on every BIS-coded item; bulk MOQ pricing matters more than exotic-grade depth.
OEM fabrication shops at Dada Nagar / Panki
Skid-mounted equipment builders, packaged boiler manufacturers and the smaller hydraulic-system shops serving the regional auto-component cluster. Buy mixed-cart loads of elbows, tees and reducers in 1"-4" sizes against weekly draws.
PWD, Jal Nigam and municipal contractors
Documentation-heavy buyers. Demand BIS-marked material, MTC per heat, e-way bill matching the consignee and (on larger tenders) Third-Party Inspection at the supplier yard before dispatch.
Dispatch and delivery — Kanpur and beyond
Fittings are dispatched from the Bartan Bazar / Basanti Nagar yard alongside pipe consignments wherever the BOQ allows. For fittings-only loads we ship via parcel or shared transport for smaller weights and dedicated trucks for full-load orders.
- Kanpur city + Dada Nagar / Panki / Jajmau: same-day pickup or local-tempo dispatch for stocked sizes on PO before noon.
- Lucknow and the 80 km belt: next-working-day delivery via the NH-27 corridor. See our Lucknow steel pipe page for the wider product line.
- Prayagraj, Varanasi, Unnao, Agra: one to two working days in transit after dispatch. Bihar destinations two to three working days.
- Documentation packet: GST invoice, e-way bill matched to consignee, MTC per heat number, and where the tender asks for it, TPI release note from the nominated agency.
