Haihao Group has completed the production and dispatch of a multi-grade seamless steel pipe consignment tailored for a critical gas processing and industrial fluid transport project in Turkmenistan. Engineered under dual ASME standards, this shipment supplies high-pressure carbon steel line pipe and corrosion-resistant austenitic stainless steel pipe to meet complex piping class requirements.
Shipment Manifest & Technical Specifications
Partnering with a proven ASTM A106 Grade B PSL2 seamless pipe supplier ensures full heat-traceability, strict chemical-mechanical compliance, and exact schedule matching across different piping classes. Below is the specification breakdown for the Turkmenistan consignment:
Heavy-Wall Carbon Steel Pipe (Piping Class B013): DN40 (1.5″) | Schedule: SCH 160 | Plain End (PE) | Standard: ASME B36.10M | Material: ASTM A106 Grade B / API 5L Grade B (PSL-2) | Type: Seamless.
Standard-Wall Carbon Steel Pipe (Piping Class B013): DN100 (4″) | Schedule: SCH 40 | Beveled End (BE) | Standard: ASME B36.10M | Material: ASTM A106 Grade B / API 5L Grade B (PSL-2) | Type: Seamless.
Austenitic Stainless Steel Pipe (Piping Class B020): DN50 (2″) | Schedule: SCH 40S | Beveled End (BE) | Standard: ASME B36.19M | Material: ASTM A312 TP316L | Type: Seamless.
ASME B36.19M ASTM A312 TP 316L Seamless Pipes Manufactured By Haihao Group
Dual-Grade Versatility: Dual-Certified Carbon & 316L Stainless Metallurgy
Industrial gas processing facilities in Turkmenistan operate across diverse pressure profiles and corrosive conditions. The carbon steel pipes supplied for Class B013 are dual-certified to ASTM A106 Grade B and API 5L Grade B PSL-2, providing superior impact toughness and tight yield-to-tensile ratios under high pressure.
For corrosive process loops, the Class B020 stainless steel pipes were forged from low-carbon ASTM A312 TP316L material. The molybdenum content in 316L steel delivers outstanding resistance to pitting and crevice corrosion, while its ultra-low carbon level prevents intergranular carbide precipitation during field welding.
End Preparation & Quality Verification
As a trusted ASTM A106 Grade B PSL2 seamless pipe supplier, Haihao Group enforced rigorous quality control protocols prior to export packaging:
End Finishing Options: The DN40 SCH 160 pipes were provided with square-cut plain ends (PE) for high-pressure socket or custom joint fit-up, while the DN100 carbon and DN50 stainless pipes featured precision 37.5° beveled ends (BE) for field butt-welding.
Hydrostatic & NDT Testing: Every pipe underwent 100% non-destructive examination (ultrasonic/eddy current) and hydrostatic pressure testing to guarantee zero boundary defects under operating stress.
Traceability & Surface Care: Carbon steel pipes received temporary rust-inhibiting surface protection, while stainless steel pipes were solution-annealed and passivated. Complete EN 10204 3.1 Mill Test Certificates were issued, covering dual-grade chemical heat analysis, Charpy V-notch impact test values, and pressure test logs.
Sourcing through a certified ASTM A106 Grade B PSL2 seamless pipe supplier guarantees full code alignment and zero downtime during field integration.
