Both screw pumps (single screw) and rotary lobe pumps are positive displacement pumps, primarily used for conveying high-viscosity pastes and shear-sensitive materials. They are self-priming, and their flow-through components can be made of 316L stainless steel, while seals are made of FDA-compliant EPDM or PTFE. Although their applications overlap, their structures differ, resulting in significant differences in conveying performance, maintenance methods, and material compatibility.

Stainless steel flanges are widely used in various industrial sectors, from heavy chemical industry to pharmaceuticals and food processing.

Stainless steel piping systems are widely used in various industrial sectors, from heavy chemical industry to high-purity biopharmaceuticals. However, there is a fundamental gap in cleanliness requirements between "industrial grade" and "hygienic grade," and the logic behind their connection methods is also completely different.

Butterfly valves, as a type of valve with a simple structure and rapid opening and closing, play an important role in industrial pipeline systems. When stainless steel is chosen as the main material of a butterfly valve, its design needs to make fuller use of the corrosion-resistant properties of the material, based on the general butterfly valve structure.
