Recently, LIB successfully completed the factory inspection, commissioning, and technical training for a Mixed Noxious Gas Corrosion
Chamber ordered by an Indian agent. The project included detailed equipment inspection, operational guidance, gas control calibration, safety system verification, and maintenance training to ensure stable long-term operation after delivery. This cooperation further strengthens LIB's partnership with the Indian market and demonstrates LIB's professional capabilities in corrosion and environmental reliability testing solutions.
【LIB Provides Advanced Mixed Noxious Gas Corrosion Testing Solutions】
LIB's Mixed Gas Flow SO₂ H₂S NO₂ Cl₂ Corrosion Chamber is specifically designed to simulate complex industrial atmospheric corrosion environments through precise control of corrosive gases, temperature, humidity, and airflow circulation. The chamber is widely used for accelerated corrosion testing of metals, coatings, electronic components, connectors, automotive parts, and electrical systems exposed to polluted industrial or coastal environments.
The system supports accurate mixed-gas testing involving SO₂, H₂S, NO₂, and Cl₂ gases in accordance with international corrosion testing standards including IEC 60068-2-42, IEC 60068-2-43, IEC 60068-2-60, ASTM B845, ASTM B827, ISO 9227, MIL-STD-810, ISO 16750, and GB/T 2423 series standards.
【Precise Gas Control and Stable Environmental Simulation】
The Mixed Gas Flow Corrosion Chamber uses high-precision mass flow controllers to independently regulate SO₂, H₂S, NO₂, and Cl₂ gas concentrations before mixing them uniformly inside the chamber. The gas concentration can be adjusted according to different testing requirements, helping customers accurately reproduce industrial pollution, exhaust emissions, and marine atmospheric corrosion conditions.
Typical testing parameters include:
|
Temperature range: 15 ℃ to 100 ℃ Humidity range: 30 % to 98 % RH SO₂ concentration: 1–30 ppb H₂S concentration: 10–100 ±10 ppb |
NO₂ concentration: 200 ±20 ppb Cl₂ concentration: 10–20 ±5 ppb Air exchange rate: 3–10 times/hour |
The equipment integrates PID intelligent temperature and humidity control technology, maintaining temperature fluctuation within ±0.5 ℃ and humidity deviation within ±1 % RH. A built-in centrifugal airflow circulation system ensures uniform gas distribution throughout the test area, eliminating dead zones and improving testing consistency.
【Corrosion-Resistant Design and Comprehensive Safety Protection】
To withstand long-term acidic gas exposure, the chamber interior is manufactured using SUS316 stainless steel, while the exterior adopts A3 steel plates with protective coating. The gas pipelines are specially treated to prevent corrosion and leakage during long-term operation.
For hazardous gas testing applications, LIB integrates multiple protection systems including:
|
Gas leakage detection system Automatic exhaust neutralization unit Over-temperature protection Over-current protection |
Water shortage protection Emergency shutdown protection Earth leakage protection |
The chamber also features an electromagnetic door lock, programmable color LCD touch screen controller, Ethernet communication, PC Link remote monitoring, and automatic water purification supply system for stable and intelligent operation.
【Comprehensive Inspection and Technical Training for India Agent】
During the factory inspection process, LIB engineers conducted complete equipment performance verification together with the Indian agent, including gas concentration calibration, temperature and humidity stability testing, airflow uniformity inspection, and safety protection system checks.
LIB's technical team also provided detailed operational training covering:
|
Mixed gas flow control operation Standard test programming Daily maintenance procedures |
Gas sensor calibration Safety operation guidelines Troubleshooting methods |
The Indian agent highly recognized the chamber's stable performance, precise gas control capability, and intelligent operating system. Through this training program, the customer can independently operate and maintain the equipment efficiently after installation.
【LIB Delivers Full-Service Global Support】
In addition to advanced corrosion testing equipment, LIB provides comprehensive global service support for all customers:
|
Customized chamber sizes and gas configurations Sample holder customization for different industries 36-month warranty and lifetime technical support 24/7 English-language after-sales service |
Global spare parts delivery within 7–15 days Remote troubleshooting and online technical assistance Export-standard packaging and international logistics support |
"Through this successful inspection and training project, we further strengthened cooperation with our Indian partner and demonstrated LIB's professional technical capabilities in mixed gas corrosion testing," said LIB's Global Sales Director. "LIB will continue providing reliable environmental testing solutions and complete after-sales support for customers worldwide."
