Haihao Group has completed manufacturing, non-destructive testing, and precision cutting for a specialized batch of alloy, stainless, and duplex steel pipes destined for an industrial energy project in Russia. Engineered to withstand high pressures and extreme sub-zero ambient temperatures, this shipment features custom-selected raw materials crafted strictly to American pressure piping standards.
Operating conditions in Russian energy plants demand severe mechanical durability and precise thermal resistance. To fulfill these multi-spec requirements, the procurement team specified ASME B36.10 seamless steel pipe products spanning four distinct alloy families, supplied in fixed 6-meter lengths with plain end (PE) square cuts for automated site fit-up.

High-Pressure & Low-Temperature Material Performance
Selecting the correct material alloy is vital when designing pressure systems exposed to extreme operational stress:
Alloy Steel A335 P22 (1 1/2″ SCH 160): Containing 2.25% Chromium and 1% Molybdenum, A335 P22 provides high-temperature creep strength, making it ideal for power plant steam lines and reformer units.
Low-Temperature Steel A333 Grade 6 (3/4″ & 1″ SCH 160): Formulated for impact resistance down to -45°C (-50°F), these heavy-wall SCH 160 pipes prevent brittle fracture in cryogenic processing and sub-arctic gas transportation.
Austenitic & Duplex Alloys (3/8″ SCH 40S): The inclusion of dual-certified 304/304L stainless and UNS S31803 duplex steel ensures high corrosion resistance in acidic bypass and instrumentation lines.
As a leading exporter, Haihao Group guarantees that each ASME B36.10 seamless steel pipe meets exact chemical and impact test parameters, verified by EN 10204 3.1 certification.

Precision Fabrication & Fixed-Length Processing
To eliminate field cutting and scrap on-site in Russia, the client specified exact 6.0-meter fixed lengths for the entire shipment. Haihao Group’s machining workshop utilized precision band sawing to deliver clean, square plain ends (PE) without thermal alteration or burrs, ensuring effortless socket welding or end-to-end fitment.
Every single ASME B36.10 seamless steel pipe was subject to rigorous quality checks. Wall thickness checks via ultrasonic gauge ensured zero wall thinning on the SCH 160 heavy-wall components. Following inspection, the pipes were treated with anti-rust oil, end-capped, and bundled using heavy-duty steel strapping for long-distance transit across rail and maritime routes.
