Stainless Steel NB Tubes - Hisar, Haryana
Nominal bore SS tube for process, instrumentation & equipment lines.
Overview
The One Pipe Where a Single Measurement Decides Fit
NB tubes from Bharat Stainless Steel Industries are confirmed against your drawing before manufacturing, because NB and OD look interchangeable on paper and aren't on delivery.
Bharat Stainless Steel Industries manufactures stainless steel NB (Nominal Bore) tubes in 200, 300, and 400 series grades, ERW/welded/OD construction, 0.20mm to 2.00mm thickness, 6mm up to 4 inch NB size, standard 2B Prime finish - used in process piping, instrumentation lines, and equipment manufacturing.
NB tubes are specified by an approximate internal-diameter naming convention, commonly used where precise internal flow diameter matters more than outer dimension.
Bharat Stainless Steel Industries, a stainless steel tube manufacturer in Hisar, Haryana, supplies NB tubes with same-day WhatsApp pricing.
NB and OD are the two measurements buyers most often confuse on this product - NB is a naming convention for approximate internal diameter, while OD is the actual measured outer diameter. Getting this wrong on an order causes a real fitting mismatch downstream, so we confirm which measurement your drawing specifies before manufacturing begins, every time.

Why BSSI
Where We Catch the NB vs OD Mistake Before It Ships
Where Bharat Stainless Steel Industries catches the mistake before it becomes a reorder.
NB tube is the product where a single measurement misunderstanding - NB vs OD - causes the most real-world fitting problems in this industry, so BSSI treats confirming that measurement as a standard step on every order, not something we assume the buyer already has right. Weighbridge-verified before dispatch.
15+ years supplying pharma, chemical, and instrumentation buyers has taught us that a five-minute confirmation call before manufacturing saves a much more expensive reorder after delivery.
