Customer Background

BASF / TOYO — Guangdong Integrated Project is a recognized participant in the industrial gas and specialty chemicals sector. The company’s operations involve process equipment that must meet stringent safety, quality, and performance standards demanded by the industry and regulatory authorities.

This project required Towers, HEX engineered to GB standards using ti, 316, reflecting the technical demands of the application and the client’s commitment to equipment reliability and regulatory compliance.

Challenges and Engineering Requirements

Thermal-Hydraulic Design for industrial gas and specialty chemicals applications

The heat exchanger design must balance heat transfer performance against pressure drop constraints on both the shell and tube sides. In industrial gas and specialty chemicals service, fouling factors, fluid properties at operating temperatures, and flow-induced vibration all influence tube layout, baffle spacing, and nozzle sizing. The design must achieve the specified duty while meeting the allowable pressure drops dictated by the process system.

Material Selection for Corrosion Resistance

Operating conditions in industrial gas and specialty chemicals expose heat exchanger surfaces to aggressive media that challenge standard carbon steel construction. The selection of ti, 316 addresses the corrosion environment specific to industrial gas and specialty chemicals service conditions. The material specification must account for both general corrosion rates and localized attack mechanisms — pitting, crevice corrosion, and stress corrosion cracking — that can cause premature failure at tube-to-tubesheet joints and other high-stress locations.

Code Compliance and Third-Party Inspection

Fabrication to GB requires documented quality control at every stage: material traceability from mill certificate to installed component, qualified welding procedures with welder performance qualifications, NDE per the applicable code requirements, and hydrostatic testing. Third-party inspection by the authorized inspector adds coordination overhead but provides the independent verification that end users and regulators require.

Why BASF / TOYO — Guangdong Integrated Project Selected Lmart

Multi-code fabrication capability. Lmart holds ASME U stamps, PED certification, and Chinese GB manufacturing licenses, enabling fabrication to whichever code the project requires — or multiple codes simultaneously for projects with mixed regulatory jurisdictions.

Special materials workshop. Lmart’s workshop is equipped for fabrication in duplex stainless steels, nickel alloys (Alloy 625, 825, C276), titanium, and other corrosion-resistant alloys. Dedicated material handling procedures prevent cross-contamination between carbon steel and alloy work.

Engineering and documentation depth. Each heat exchanger is delivered with a complete documentation package: design calculations per TEMA/HTRI standards, fabrication drawings, material certificates, weld maps, NDE reports, and hydrostatic test records. For international projects, documentation is prepared in the language and format required by the end user and their inspection agency.

Engineering and Manufacturing Solution

Lmart engineered and fabricated Towers, HEX for BASF / TOYO — Guangdong Integrated Project to GB using ti, 316. The scope of supply included complete detail design, material procurement, fabrication, inspection, testing, and documentation.

Key engineering considerations for this project included thermal-hydraulic performance optimization, material selection for the specific process environment, and compliance with GB requirements for design, fabrication, and inspection.

The equipment was manufactured at Lmart’s Zhangjiagang facility, which provides full-cycle fabrication capabilities including plate rolling, head forming, machining, welding (SAW, GTAW, SMAW), post-weld heat treatment, and NDE — all under a single quality management system.

Quality Control and Project Execution

All equipment was manufactured under Lmart’s ISO 9001-certified quality management system with the following key inspection milestones:

• Material verification: Incoming inspection of all plates, forgings, and fittings against mill certificates; PMI spot checks on alloy materials
• Welding quality: All welding performed by qualified welders using approved WPS/PQR; NDE per GB requirements including RT/UT on pressure-retaining welds
• Dimensional inspection: In-process dimensional checks at shell rolling, head forming, and final assembly stages
• Pressure testing: Hydrostatic test to GB requirements, witnessed by the authorized inspector and/or client representative
• Documentation package: Complete data book including material certificates, weld maps, NDE reports, dimensional records, and test certificates

Equipment was delivered to BASF / TOYO — Guangdong Integrated Project’s project site, meeting the project schedule requirements.

Results and Business Impact

Lmart successfully delivered Towers, HEX to BASF / TOYO — Guangdong Integrated Project, meeting the project’s quality, schedule, and documentation requirements. The equipment was manufactured in ti, 316 to GB standards, with full documentation packages accepted by the client and applicable inspection authorities.

This project reinforces Lmart’s position as a qualified manufacturer for industrial gas and specialty chemicals applications, demonstrating the company’s ability to deliver equipment that meets international quality and certification standards.

Customer Voice

“The equipment was delivered on schedule and the documentation package was complete. The quality of fabrication met our inspection requirements.”
