Gail HDPE G-Lene P46A010U
Gail HDPE G-Lene P46A010U is a UV-stabilized, ethylene-hexene copolymer high density polyethylene (HDPE) pipe-extrusion grade from GAIL (India) Limited. It is recommended for PE63-class pressure pipe systems used in potable-water distribution, sprinkler/irrigation networks, effluent and waste-water pipelines, and cable/duct applications.
GAIL positions P46A010U as meeting hydrostatic strength requirements for PE63 material as per IS 4984:2016, and the TDS states that the resin conforms to the natural-resin designation IS 7328-3H-PB-EXTA under IS 7328:2020. In practical terms, this grade is built for pipe converters who need a very-low-MFI resin that supports long-term performance, good stress-crack resistance, and stable extrusion of pressure-pipe and duct profiles.
Because P46A010U is UV-stabilized (HALS-type positioning), it is also a strong fit for pipes and ducts that may see sunlight exposure during storage, transport, or initial installation before burial/cover.
Technical insights
Pipe-grade HDPE is typically evaluated on flow (for extrusion control), density/modulus (for stiffness and dimensional stability), and crack/impact resistance (for installation and long-term reliability).
Melt Flow Index (MFI): P46A010U is positioned as a very-low-MFI pipe resin. Typical values provided in your inputs include I2 0.22 g/10 min and I5 0.95 g/10 min. Lower I2 is commonly associated with higher molecular weight, which can support better long-term creep and stress-crack resistance in pressure-pipe applications (with the trade-off of higher extrusion torque).
Density: Typical density is cited as 0.948 g/cm³ in your inputs. In HDPE pipe, density is one of the indicators used for stiffness and dimensional stability, supporting consistent pipe geometry and performance under load.
Tensile strength and elongation at yield: Your inputs cite tensile strength at yield 230 kg/cm² and elongation at yield 12%. This kind of profile supports ductility during handling/installation and helps reduce brittle-type failures during bending and joining (actual field performance depends on pipe design and processing).
Flexural modulus: Flexural modulus is commonly used as a practical stiffness indicator for pipe profiles. Your inputs cite 8700 kg/cm², supporting the positioning for PE63 pipe and duct applications where dimensional stability matters.
ESCR: ESCR (ASTM D1693B) is a key screening metric for pipe resins, especially where installation conditions and service environments can introduce stress concentrators. Your inputs cite >48 hours (10% Igepal solution v/v, F50), indicating a grade positioned for improved stress-crack resistance.
Impact strength: Notched Izod impact strength is often used to compare toughness across pipe grades. Your inputs cite 120 J/m, supporting resistance to knocks during transport and installation.
UV stabilization: UV stabilization is a practical differentiator for pipe/duct materials that may sit outdoors at site or remain partially exposed. It helps slow sunlight-driven degradation that can cause embrittlement and surface cracking over time.
Applications
Potable-water pressure pipes (PE63 systems)
P46A010U is recommended for potable-water pressure pipe systems where hydrostatic strength class and long-term reliability are key. The grade’s PE63 positioning (IS 4984:2016) and very-low-MFI profile align with applications that prioritize sustained performance under internal pressure.
Sprinkler and irrigation pipelines
For sprinkler and irrigation networks, converters and project buyers typically look for a balance of stiffness, impact resistance, and crack resistance to handle field installation stresses. UV stabilization is beneficial when pipes are stored outdoors before installation.
Effluent and waste-water pipelines
In effluent and waste-water systems, resistance to slow crack growth and installation damage is often a priority. P46A010U’s pipe-grade positioning and ESCR-focused property set support these use cases for PE63-class networks.
Cable/telecom ducts and protective conduits
P46A010U is also recommended for cable/duct pipelines where consistent extrusion, dimensional stability, and toughness matter. UV stabilization is useful for duct coils stored outdoors at site or exposed during staged installations.
Comparable alternatives (positioning without claiming equivalence)
Comparable HDPE pipe grades in India include GAIL’s own P52A003 and other PE63-positioned materials, as well as higher-class pipe grades (e.g., PE80/PE100 families) depending on design requirements.
However, direct equivalence to P46A010U should not be assumed unless you match manufacturer technical sheets and validate on your extrusion line. Based on your inputs, P46A010U’s key differentiator is UV stabilization combined with PE63 pipe positioning, making it a practical choice where outdoor handling/storage is expected.
For substitution screening, compare MFI (I2/I5), density, ESCR, impact, and the stated IS 4984/IS 7328 conformity first—then confirm output rate, melt pressure, surface finish, and pipe test performance via trials.
