These encompass production processes, raw material requirements, utility requirements, infrastructure needs, machinery and technology requirements, manpower requirements, packaging requirements, transportation requirements, and more.
Salt glazed stoneware pipes are vitrified clay pipes produced through a high-temperature kiln firing process where salt is introduced to create a smooth, glassy, corrosion-resistant surface, which makes them highly durable for demanding environments. These pipes have low water absorption (under 6%), high crushing strength (22-40 kN/m), and excellent resistance to acids, alkalis, and sewage gases, complying with standards like IS 651:2007 and BS 65. They are used in factories for handling corrosive industrial wastewater due to their superior chemical inertness. They are also utilised in industrial sites for sewage lines and stormwater management. Additionally, they find applications in agricultural and water systems, mainly in irrigation or culvert systems, where durability is required.
The market growth for salt glazed stoneware pipes is driven by global investments in modernising municipal sewage, drainage, and wastewater infrastructure, as governments prioritise durable solutions for efficient sanitation. Their superior corrosion resistance to acids, alkalis, and abrasion, coupled with low maintenance needs and long service life, boosts demand in industrial effluent discharge and underground systems where reliability is required.
Additionally, the push for sustainable, eco-friendly materials with minimal environmental impact, along with advancements in production for better quality and customisation, further propels growth amid rising construction in developing regions. Industrial salt glazed stoneware pipe procurement is influenced by raw material prices (clay, salt), production expenses, transportation, and long-term savings from durability/low maintenance.
Raw Material for Salt Glazed Stoneware Pipe Production
According to the salt glazed stoneware pipe production plant project report, the various raw materials for salt glazed stoneware pipe production include stoneware clay (rich in silica and alumina) and feldspar.
Production Process of Salt Glazed Stoneware Pipe
The extensive salt glazed stoneware pipe production cost report consists of the following major industrial production process:
- Production via extruding or moulding: The production process of salt glazed stoneware pipes starts by first blending stoneware clay rich in silica and alumina with grog and fluxes like feldspar for plasticity and strength. The next step involves extruding or moulding the mixture into pipe shapes with socket-and-spigot joints, followed by slow drying to prevent cracking. The dried pipes undergo bisque firing at 900-1,000 °C for initial hardening, followed by high-temperature firing at 1,100-1,300 °C in a kiln where salt (NaCl) is introduced. The next step is followed by vaporising into sodium that reacts with silica to form a smooth, glassy, impermeable sodium silicate glaze for corrosion resistance. Finally, the pipes cool gradually to avoid thermal stress, followed by rigorous quality inspections for dimensions, crushing strength (22-40 kN/m), and water absorption (<6%) per standards like IS 651.
Properties of Salt Glazed Stoneware Pipe
Salt glazed stoneware pipes are vitrified clay products having a durable, glassy sodium aluminosilicate surface formed by vaporising salt in a kiln at 1,100-1,300 °C, which reacts with silica and alumina for superior corrosion resistance to acids, alkalis, and sewage gases. They have low water absorption (max 6% per IS 651:2007/BS 65), high crushing strength (22-40 kN/m), abrasion resistance, and standard dimensions like 90-590 mm diameters, 12-35 mm wall thickness, and 600-1,000 mm lengths with socket-and-spigot joints. Additionally, they are chemically inert and non-porous.
