TU 1468 P5 Alloy Pipe Fittings Shipped to Russia for Cold Service Pipeline

This shipment for our Russian client is manufactured to local Russian technical specifications TU 1468, a frequent requirement for domestic oil and gas trunk lines. The batch includes 3D elbows at 45° and 90°, paired with type 2 elliptical end caps, all produced in P5 alloy steel with chromium content above 4.50%. This TU 1468 P5 pipe fitting is engineered to sustain stable mechanical performance under sub-zero operating conditions, a core design factor for pipeline assets across Russia’s cold regions.

All TU 1468 P5 pipe fitting components undergo dedicated heat treatment to lock in the required tensile and yield properties. The acceptance criteria are fixed: tensile strength minimum 569 MPa, yield strength 412 MPa, and elongation reaching 16%. Beyond standard tensile checks, the specification mandates U-notch impact testing at -40℃, with impact toughness not falling below 30 J/cm². Our QC team prepares coupons from each heat lot separately, so every batch of TU 1468 P5 pipe fitting can be traced back to its full test dataset before dispatch.

TU 1468 001 P5 alloy 45° 90° elbows and TU 1468 002 elliptical pipe caps for Russia low temperature pipeline

The elbows follow the TU 1468-001-17192736-01 standard, with bending radius marked R=1.5D, covering sizes 89×7 mm, 159×8 mm and 426×12 mm. We supplied both 45° and 90° variants, matching the bend layout of the client’s piping route. The matching elliptical plugs (end caps) are built to TU 1468-002-17192736-03, type 2, dimension 426×12 mm and height of 125 mm. Bevel preparation on all butt weld ends follows the C17 drawing requirement as specified by the buyer.

Many Russian EPC teams prefer TU 1468 P5 pipe fitting over conventional ASME grades for projects that must adhere strictly to Russian technical documentation. P5 alloy with elevated chromium content delivers good resistance to high-temperature oxidation while still holding acceptable toughness at -40℃, balancing two conflicting performance demands for process and transmission pipelines. Each piece is clearly marked with the standard designation, heat number and material grade to simplify site receiving and third-party inspection.

We compile a complete documentation package for the shipment, including heat treatment records, tensile test reports, U-notch impact test results and dimensional check sheets. Every dimension, bend radius, wall thickness and bevel profile is verified against the client’s drawing, to avoid fit-up delays once the fittings arrive at the construction site.

If you are sourcing elbows, elliptical caps or other butt weld fittings made to Russian TU specifications for cold climate pipelines, send your drawing and mechanical acceptance requirements to our engineering team. We can quote P5 alloy and other grades, with full test certificates aligned with local project acceptance rules.
