Supply of LPG Composite Cylinders 10kg Capacity by Pakistan State Oil Company

Pakistan State Oil Company Limited invites quotations for the supply of locally manufactured LPG composite cylinders with 10kg capacity at its LPG Plant in Korangi, Lahore, Sindh. The procurement covers 800 units of fully wrapped fibre reinforced composite gas cylinders designed for storing liquefied petroleum gas in the residential sector. The cylinders shall be manufactured from OGRA approved sources and must comply with international standards including ISO 11119-3, BS EN 14427, and DOT SP 12706 specifications. Each cylinder comprises a blow-molded HDPE inner liner wrapped with fiberglass and epoxy resin, fitted with an HDPE outer jacket, with water capacity of 24 litres and maximum service pressure of 294 psi (20 bars).

Quotations must be submitted by 13 August 2026. Bidders must ensure all material is sourced from PSO-approved suppliers, with comprehensive documentation including Material Test Certificates from accredited laboratories, batch numbers, and TPAI certificates for safety components. The manufacturer shall submit detailed dimensional design drawings with dimensional tolerances, reinforcement patterns, exterior coating specifications, hydro test pressure, and burst pressure calculations for PSO approval prior to manufacturing. All polymer base materials must be uniform and homogeneous in quality, with fiberglass meeting ASTM D 2343-79 requirements and resin systems demonstrating minimum shear strength of 13.8 MPa per ASTM D 2344-67.

Detailed specifications including composite wrap materials, valve specifications, and technical data requirements are provided in the tender document. Bidders must have capacity to supply cylinders dimensionally equivalent to 306mm diameter and 580mm length with 5.5kg weight or equivalent to the specified water litre capacity. Contact Pakistan State Oil Company Limited at PSO House, Khayaban-e-Iqbal, Clifton, Karachi for further information and tender document acquisition.

PSO seeks 800 LPG composite cylinders (10kg capacity) for supply to Korangi plant. This is a straightforward commodity procurement from OGRA-approved manufacturers. The specification is rigid and standards-heavy (ISO 11119-3, BS EN 14427, DOT SP 12706), requiring design approval before manufacturing—typical for pressure vessels. Suppliers must source all components from PSO-approved vendors and maintain full traceability (batch numbers, test certificates). Tight deadline (15 days to quotation) and the requirement for pre-manufacturing design submission suggest PSO has urgent capacity needs. One-off purchase, not a framework agreement.

Who can bid: Bidders must be manufacturers of LPG composite cylinders with OGRA approval or sourcing from OGRA-approved manufacturers. All materials and components (valves, safety caps, liners) must be procured from PSO-approved suppliers. Suppliers must obtain Material Test Certificates from accredited laboratories and provide TPAI certificates for safety components. Typically, SECP registration, valid NTN, and documented manufacturing or distribution capability are required.
