Quality as the Foundation, Integrity as the Bridge——Our Insulation Sleeves Are Exported to Vietnam

On a winter afternoon, the campus of Jiecheng Company is bathed in pale golden sunlight: outside the window, shrubs draped in bright yellow leaves sway gently, the glass of distant buildings reflects the pale blue sky, and the silence is broken only by the soft rustle of wind brushing through the branches.

2026 has arrived as promised, brimming with fresh hope and boundless possibilities, and a magnificent new journey has officially begun! Jiecheng Novel Materials Co., Ltd. hereby extends our sincere and warmest New Year greetings and best wishes to every partner who has walked alongside us, every customer who has trusted and supported us, and every colleague who has devoted themselves to the industry!

Currently, the attached images of the insulation sleeves are based on on-site feedback from visiting clients at this workshop. The exposed valves operate at an internal working temperature of up to 170℃, with the surrounding ambient temperature reaching approximately 70℃—an extremely high level. Notably, a surface temperature of 110℃ far exceeds the human body's tolerance limit, posing a significant scald risk to on-site operators. Meanwhile, the elevated ambient temperature around the equipment may compromise working comfort and reduce production efficiency. High temperatures directly translate to substantial heat energy dissipation, meaning the energy consumed during equipment operation is not effectively utilized in the production process but wasted as heat. Long-term operation will inevitably drive up energy costs. Furthermore, sustained high temperatures can accelerate the aging and wear of equipment components such as outer cladding materials and seals, increasing the likelihood of equipment failures and maintenance frequency, which indirectly raises production and operational costs.?

This evaluation conducts an analysis on the energy-saving benefits achieved after installing thermal insulation jackets on valves and equipment. Before the renovation, the high-temperature components of valves and equipment dissipated a large amount of thermal energy through radiation and convection, resulting in ineffective energy consumption. Meanwhile, it elevated the ambient temperature of the surrounding area, which compromised the comfort of operation and the stability of equipment operation. The installed insulation layer can mitigate the temperature fluctuations of equipment, reduce thermal stress damage, and lower the failure rate as well as maintenance costs. From the perspective of return on investment, the renovation input can be recovered within a short period through energy-saving gains. It delivers both economic and environmental benefits, providing strong support for the green and low-carbon development of enterprises. Field test results show that: the indoor ambient temperature is approximately 45–60℃, and the exposed surface temperature of operating valve equipment ranges from 110℃ to 190℃. The heat loss in all cases has seriously exceeded the maximum allowable heat dissipation value specified in the national standard GB/T 8174-2008.?
