Import A335 P91 / A335 P9 / A335 P22 / A335 P5 Pipes — Buy in Bulk from Supplier in India

Kalp Overseas supplies seamless alloy steel pipes in ASTM A335 Grades P91, P9, P22 and P5 from their base in Mumbai, Maharashtra. These grades cover the chromium-molybdenum spectrum from the moderate-alloy P5 (4-6% Cr, 0.45-0.65% Mo) through P9 (8-10% Cr, 0.9-1.1% Mo) and P22 (2.0-2.5% Cr, 0.9-1.1% Mo) to the advanced P91 (8-9.5% Cr, 0.85-1.05% Mo, plus V, Nb, N). The seamless construction eliminates longitudinal weld seams, providing uniform circumferential strength and removing the primary failure initiation site found in welded pipe. The listing does not specify outer diameter, wall thickness schedules, or length ranges; buyers must request these dimensional details directly.

The P91 grade represents the highest alloy level offered, designed for ultra-supercritical boiler and heat exchanger service with design metal temperatures up to approximately 650 degrees Celsius and allowable stresses significantly exceeding P22 at equivalent temperatures. P22 serves intermediate temperature-pressure regimes common in subcritical power plants and petrochemical steam headers.

Mumbai's Khetwadi area lies in the city's traditional metal and engineering trading district, though this location context does not distinguish between stockholding, trading, or manufacturing operations.

The supplier profile contains no stated year of establishment, employee count, annual turnover, factory location, production equipment, or specific client references. The description positions the company as offering flexible trade options with LC and TT payment terms, though these appear as general capabilities rather than confirmed arrangements. For Indian alloy steel pipe sourcing, buyers should verify whether Kalp Overseas holds direct mill relationships with primary producers such as Maharashtra Seamless, Jindal Saw, or import arrangements with foreign mills, or whether they operate as a secondary trader. Request direct verification of any claimed ISO 9001 certification with certificate number and UKAS or equivalent accreditation mark.
