Selecting the Right Food Grade EPDM Hose for Low-Concentration Sodium Hydroxide Transfer
EFSC Food Grade Hot Water and Steam Hose for High-Purity Chemical Processing
Introduction
Modern chemical processing facilities increasingly require fluid transfer systems that combine chemical resistance, hygienic materials, and long-term operational reliability. This trend is especially evident in high-end chemical manufacturing, where production processes often involve cleaning chemicals, process additives, or ingredients that require food-grade compliant materials.
Although sodium hydroxide (NaOH) is a common industrial chemical, applications involving low-concentration alkaline solutions and hygienic process environments demand careful hose material selection. The transfer hose must provide reliable chemical compatibility while meeting cleanliness expectations and maintaining stable performance under elevated temperatures.
To support these requirements, CJan Fluid Technology Co., Ltd. recommended the EFSC Food Grade EPDM Hot Water and Steam Hose for a chemical processing application requiring hygienic construction and dependable fluid transfer.
