Why choose us?

Diverse Tower and Internals Supply

We provide a wide range of towers and internals in materials like special alloys, ceramics, graphite, plastic, and stainless steel. Liquid distributors (orifice, trough, ladder, spray nozzle types) and gas distributor spargers are designed for uniform distribution, considering scaling/foaming factors. Packing supports, bed limiters, and mist eliminators (mesh/chevron types) are offered to enhance purity and prevent equipment damage.

Comprehensive Chemical Technology Support

With an expert team, we offer full-cycle technical support and consulting 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.

High-Quality Industrial Equipment Provision

Specializing in chemical industry equipment, we offer top-grade materials resistant to corrosive/abrasive chemicals (solvents, acids, oils, etc.). Product lines include diverse pumps (barrel, pneumatic diaphragm, centrifugal) and customized skid-mounted systems for single-point connection. All equipment meets API standards, with pumps complying with ANSI for guaranteed reliability.

The company provides comprehensive installation support for tower and internals, ensuring safe and efficient commissioning:
- Pre-installation planning:
- Detailed installation procedures (IPA) developed, including lifting plans (crane capacity calculation, rigging details), sequence of installation, and safety precautions.
- Mock-up installation in workshop for complex internals (e.g., multi-tray columns), verifying fit and functionality before site delivery.
- On-site installation support:
- Technical supervisors onsite to oversee installation, ensuring compliance with engineering drawings and standards (bolt torque sequences, gasket placement).
- Specialized tools provided: laser alignment systems for tray support beams (accuracy ±0.5 mm/m), hydraulic lifting systems for heavy internals.
- Post-installation testing:
- Water distribution testing: Flooding the tower with water to verify liquid distribution uniformity (sample points at tower cross-section, variation < 5%).
- Gas flow testing: Air flow through tower to check pressure drop (compared to design, variation < 10%), identify leaks in flanged connections.
- Training and documentation:
- Operator training on routine maintenance (gasket replacement, manway sealing), emergency procedures (internal access safety).
- As-built documentation including installation records, inspection reports, and test certificates.

Customer Reviews

David Taylor

The liquid spray nozzle distributors are ideal for our short-bed towers in refinery operations. They deliver uniform distribution patterns, enhancing heat transfer efficiency. The stainless-steel construction resists abrasive chemicals, and the packing supports provide stable bed limits. Installation was straightforward, and the team’s guidance on maintenance has extended equipment lifespan.

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!
