The company adheres to strict quality standards for tower and internals, ensuring products meet or exceed industry requirements:
- Material standards:
- Stainless steels: ASTM A240, A312; exotic alloys: ASTM B575, B622.
- Welding consumables: AWS A5.9 (stainless steel), AWS A5.11 (nickel alloys).
- Manufacturing standards:
- Pressure vessels: ASME Section VIII, Division 1; EN 13445.
- Tower internals: TEMA (for heat exchangers), API 650 (for storage tanks), but adapted for process towers.
- Testing protocols:
- Non-destructive testing (NDT): 100% visual inspection, dye penetrant testing (DPT) for welds, ultrasonic testing (UT) for thick sections.
- Hydrostatic pressure testing: 1.5 x design pressure for towers, 1.3 x design pressure for internals.
- Performance testing: Liquid distribution uniformity (±5% across tower cross-section), gas distribution pressure drop (verified via CFD simulation).
- Quality management system: ISO 9001:2015 certified, with traceability from raw material to finished product (material test reports, welding logs, inspection records).
Third-party inspection (ABS, DNV, Lloyd’s) can be arranged per client requirements.

Frequently Asked Questions

What types of towers and internals does your company supply, and what materials are used?

We supply various towers and internals, including liquid orifice distributors, trough distributors, ladder distributors, spray nozzle distributors, and gas distributor spargers. Materials include special alloys, ceramics, graphite, plastic, and stainless steel. Designed for uniform distribution in packed beds, considering factors like scaling and foaming, we also offer packing supports, bed limiters, and mist eliminators (mesh/chevron types) to enhance purity and prevent equipment damage.
Our expert team offers comprehensive support for R&D, production, process optimization, supply chain management, and environmental compliance. Services include process optimization to boost efficiency, sustainability solutions for regulatory compliance, safety risk management, IP protection strategies, and supply chain integration to reduce costs. We provide customized guidance across the entire chemical technology operation cycle.
We optimize energy efficiency in plant design through high-efficiency heat exchangers for energy recovery and energy-saving pumps/fans to lower operational energy consumption. Advanced automation controls adjust equipment parameters in real-time based on production load, preventing energy waste. We also offer energy management consulting to establish monitoring systems, achieving dual economic and environmental benefits.
Our intelligent solutions integrate big data analytics for process optimization and equipment fault prediction, AI algorithms for real-time control of reaction parameters (temperature, pressure), and IoT technology for remote equipment monitoring. Engineers can access device status, receive alerts, and perform remote maintenance via mobile devices/computers, improving operational efficiency and reliability.

Customer Reviews

Lisa Wilson

We needed tower internals for a challenging project with frequent foaming issues. The team provided tailored liquid ladder distributors that perfectly addressed our medium-to-high flow needs in the stripper column. The pressure-driven design ensures consistent distribution, and the ceramic materials withstand corrosion flawlessly. Their expertise in process factors like scaling made all the difference.

Michael Brown

The tower internals from Changzhou Sanli Tech have transformed our packed bed operations. The liquid trough distributors efficiently handle high flow rates, and the gas spargers ensure uniform steam distribution. Made from durable stainless steel and special alloys, they resist scaling even in harsh conditions. The mesh mist eliminators have significantly improved product purity while reducing equipment damage. A reliable solution for our chemical processes!
