Do you supply electropolished pipes in Guwahati?

Yes. We supply electropolished stainless pipes and tubes to plants in and around Amingaon Industrial Estate, Brahmaputra Industrial Park, mainly for food and agro processing and chemicals, petrochemicals and refining. Send the plant address with your enquiry so we can quote delivery to your site.

How long does delivery take to Guwahati?

Material for Guwahati is dispatched from Mumbai by road; delivery time depends on size, quantity and stock, and is confirmed in writing with each quotation. For export-bound projects the nearest gateway is Kolkata Port (1050 km). Manufacturing time for made-to-order sizes is separate from transit; we confirm both in writing with the quotation.

Which industries in Guwahati use electropolished tubing?

The main users in Guwahati are food and agro processing and chemicals, petrochemicals and refining. Food and agro-processing units in Guwahati use sanitary stainless tube on product-contact, syrup, edible-oil and CIP lines. Chemical and petrochemical units in Guwahati mostly run process piping in carbon steel or higher alloys, often through EPC contractors.

Do you deliver to Amingaon Industrial Estate, Brahmaputra Industrial Park?

Yes. We deliver to units across Amingaon Industrial Estate, Brahmaputra Industrial Park, with Amingaon Industrial Estate the main cluster we serve. Give us the plant address with your enquiry and we will confirm the delivery route and timing for that site.

What is electropolishing and why does it matter?

Electropolishing is an electrochemical process that removes a thin layer of metal from the tube surface. It lowers surface roughness, removes the directional grain left by mechanical polishing and leaves a chromium-rich passive layer, so the surface cleans faster, resists corrosion better and gives bacteria and residues less to hold on to.

What Ra values can you achieve?

We supply electropolished tube to ASME BPE SF4, an internal Ra of 0.38 um (15 uin) or better, and to the SF1 mechanically polished grade (Ra <= 0.51 um / 20 uin) where electropolishing is not required. Every EP lot ships with an Ra report.

What is the difference between electropolished and mechanically polished tube?

Mechanical polishing abrades the surface and leaves directional grain lines and, sometimes, embedded abrasive. Electropolishing dissolves the surface electrochemically, rounding off micro-peaks instead of smearing them, which gives a lower and more uniform Ra and a more corrosion-resistant passive layer.

Electropolished vs pickled and passivated - which do I need?

Pickling and passivation removes scale and restores the passive layer but does not reduce roughness. Electropolishing does both. Specify EP for product-contact, WFI, clean steam and high-purity lines; pickled and passivated tube is usually enough for utilities and non-contact service.

Do you supply seamless or welded EP tube?

Both. Welded tube is the economical choice for most hygienic and water-system lines; seamless is specified where higher pressure, critical service or the end-user standard demands it. Tell us the service and pressure and we will recommend one.

Guwahati's Two Hygienic-Tube Buyers: Purabi Dairy and Sun Pharma Palashbari

Demand for electropolished and hygienic stainless tube around Guwahati comes from two very different plants. One is Purabi Dairy at Panjabari, run by the West Assam Milk Producers' Cooperative Union (WAMUL). The other is Sun Pharma's sterile-products facility at Palashbari in Kamrup district.

The dairy needs tube for milk processing, fermented products and cleaning circuits, while the pharmaceutical plant needs it for purified water, water for injection and clean steam. The two specifications differ, so a Guwahati enquiry should say which kind of plant it is for.

Purabi Dairy, Panjabari: Doubling to 3 Lakh Litres a Day

In February 2021 WAMUL said it was expanding the Panjabari plant two and a half times, to 1.5 lakh litres of milk a day by September 2022. That expansion was funded under the Assam Project for Agri-Business and Rural Transformation (APART), with an outlay of Rs 46.84 crore.

A second expansion followed. At the Advantage Assam 2.0 summit in February 2025, the National Dairy Development Board and WAMUL signed an agreement for a Rs 100 crore project to double milk processing from 1.5 to 3 lakh litres a day, raise fermented milk products from 20 to 50 tonnes a day and add a 20,000 litre-per-day ice cream plant.

Chief Minister Himanta Biswa Sarma performed the bhoomi poojan for this expansion in July 2025. Reports at the time described Purabi's Panjabari plant as the largest dairy processing facility in north-east India.

Sun Pharma's Sterile-Products Plant at Palashbari, Kamrup

In October 2018 Assam Chief Minister Sarbananda Sonowal inaugurated a new production line at Sun Pharma's Palashbari facility. The company had spent Rs 120 crore on that line, which added capacity for liquid vials, injectables, eye drops and tablets, and the state government said Sun had already invested Rs 700 crore at the site, with a further Rs 200 crore to follow.

Sun Pharma's managing director Dilip Shanghvi said he expected Palashbari to become one of the largest sterile-products facilities in the company's network. The plant has automated equipment for granulation, compression, capsule filling, eye drops, vial and ampoule filling, coating and packing.

Injectables and eye drops are the products that drive tube specification. Water for injection and clean steam reach the filling rooms through distribution loops that are qualified and validated, and those loops are where electropolished 316L tube is normally specified.

Choosing Tube for a Guwahati Dairy or Sterile Plant

At Panjabari, milk reception, pasteurisation and transfer lines are normally 304L or 316L with an SF1 mechanically polished bore. The new fermented-milk and ice cream sections justify SF4 electropolished 316L on mix and culture lines, and on hot CIP headers, because a smoother bore holds less product and cleans faster.

In a sterile plant like Palashbari, water for injection, pure steam and product-contact lines in the filling areas should be SF4 electropolished 316L to ASME BPE. Ambient purified-water loops for oral solid dosage blocks are often SF1. Do not mix finishes inside one validated loop, and keep 304L for non-contact utilities.

What to Send With a Guwahati Enquiry

Say whether the tube is for a dairy section (pasteurisation, fermented products, ice cream mix, CIP) or a pharmaceutical system (purified water, WFI, pure steam, product transfer).
Give operating and sanitisation temperatures and the CIP or SIP regime, so grade and finish match the duty.
List OD × wall and metres per size, to ASME BPE dimensions or ASTM A270 / A269, and the finish of any existing loop being extended.
Include the electropolished bends, tees, reducers and clamp ferrules needed to complete the line.
Each lot ships with an EN 10204 3.1 certificate traced to heat number, PMI on every length and a measured Ra report for electropolished tube; dispatch and transit are confirmed in writing with each quotation.
