Project Overview
Project: Russian LNG Project
Customer: Hangzhou FST Cryogenic Equipment
Industry: LNG
Application: Coil-Wound Heat Exchanger
Supply Scope
Product: Seamless Stainless Steel Coiled Tubing
Material: TP321
Size: Ø12 × 1.0 mm
Quantity: Approx. 180 tons
Project Background
The project required seamless stainless steel coiled tubing for the manufacture of coil-wound heat exchanger equipment used in an LNG application for a Russian natural gas project.
The tubing required reliable dimensional and surface quality, together with strict inspection requirements for heat exchanger fabrication.
BAOFENG Supply
BAOFENG supplied approximately 180 tons of TP321 seamless stainless steel coiled tubing in Ø12 × 1.0 mm specification to Hangzhou FST Cryogenic Equipment for the project.
The tubing was used in the manufacture of coil-wound heat exchangers.
Key Technical Requirements
• Inner surface roughness below Ra 0.8 μm
• Flattening test requirements
• Flaring test requirements
• 100% borescope inspection for every tube
• TP321 stainless steel suitable for demanding heat exchanger fabrication
Project Highlights
• Approx. 180 tons total supply
• TP321 seamless stainless steel coiled tubing
• Ø12 × 1.0 mm specification
• 100% internal borescope inspection
• Applied in LNG coil-wound heat exchanger manufacturing
Result
This project demonstrates BAOFENG’s capability to supply TP321 seamless coiled tubing for LNG heat exchanger applications requiring strict surface quality, forming performance and full internal inspection.
