For chemical, fertilizer and petrochem plants

Chemical-plant refractory work has two distinct problem zones: the hot side (reformers, SRUs, incinerators) where temperature drives the spec, and the cold/acid side (storage, pickling, ETP) where chemistry drives the spec. We supply both — refractory bricks and castables for the high-temperature reactors, and acid-resistant bricks plus chemical-set cements for the corrosion-side equipment.

What we supply: Furane resin cement (mixed chemistry), AR Class 1 bricks, bituminous membrane

Fertilizer Plant Reactors (Urea, NPK)

Wear pattern: Ammonia attack, prilling-tower abrasion, thermal cycling at reactor jacket

What we supply: 60-70% alumina bricks, low-cement castable, ceramic-fibre back-up, AR brick lining at acid-side stages

Chimneys, Stacks & Flue Ducts

Wear pattern: Acid dew-point corrosion at top, thermal cycling, condensate at base

What we supply: AR Class 2 stack bricks, K-silicate cement, fireclay brick safety lining at hot zones, refractory mortar pointing

Supply & Despatch

Chemical-plant customers in MIDC clusters around Pune, Mumbai-Tarapur and Vadodara source acid-resistant and refractory packages from our Chakan plant. We coordinate AR-brick + cement + membrane packages so the lining contractor receives matched chemistry in one consignment.

Chemicals & Petrochem questions, answered

Quick answers to the questions plant maintenance teams ask us most often.

Do you supply AR bricks to IS-4860?

Yes — Class 1 (high-acid resistance, ≤2% acid solubility) and Class 2 (general industrial) bricks supplied to IS-4860 with batch test certificates. Class 1 is standard for storage tanks; Class 2 for chimneys and stacks.

Which cement should I use for which acid?

Sulphur cement: HCl and dilute H2SO4 (fast-set, good thermal-shock). Sodium silicate cement: brick bedding/pointing on the acid side. Potassium silicate cement: concentrated H2SO4 (better acid resistance). Furane resin cement: mixed-chemistry (acid + alkali) like ETP sumps. We supply all four and recommend by service condition.

Do you supply complete acid-tank lining packages?

Yes. AR Class 1 bricks + sulphur cement (or K-silicate) + sodium silicate pointing + bituminous membrane, despatched matched. Lining contractors then handle on-site application per IS standard.

What about reformer-arch insulation?

Insulation Group 28/30 bricks for the hot face, calcium-silicate boards plus ceramic-fibre blanket for the cold face. We supply all three layers as a coordinated package and can advise on anchor brick spacing.
