Project Challenges
The laboratory pipe system needed to withstand high pressure, acid-alkaline corrosion, and complex physical stress, posing stringent requirements on pipeline connectors. The harsh winter temperatures in Harbin demanded rubber joints that maintained elasticity and sealing at extremely low temperatures. The challenge was to provide joints that resisted aging while withstanding frequent high-pressure impacts.

Product Design and Customization
We provided customized rubber joints made from 100% natural rubber, ensuring high elasticity and long service life. Special anti-corrosion coatings were applied to withstand potential acidic and alkaline substances in the laboratory pipes. Stringent quality tests ensured the rubber joints performed optimally in extremely low temperatures.

Installation and Commissioning
During installation, our technical team worked closely with Heilongjiang University engineers, ensuring seamless connection of each joint to the pipe system. We provided detailed installation manuals and on-site technical support, conducting performance tests on sealing and pressure resistance during installation.

Project Outcome
Months after installation, the laboratory pipe system ran smoothly, with the rubber joints ensuring equipment safety and efficiency. The rubber joints demonstrated excellent performance in extreme low temperatures and resistance to corrosion and wear.

Client Evaluation
Heilongjiang University highly appreciated the product quality and services provided by Shanghai Songjiang Group. The reduced maintenance requirements for the pipe system saved time and costs. The university’s engineering team also praised our customized solutions and the smooth project execution.

Summary
This successful collaboration with Heilongjiang University further demonstrated Shanghai Songjiang Group’s technological advantages in complex environments. We will continue to provide high-quality products and professional services to assist more institutions with their infrastructure upgrades.
