Nominal inside diameter: DN12-DN80 wall thickness (mm): 3.4-8 Material: EPDM Manufacturers (Origin): Hebei Hengshui Uses: acid liquids transportation or suction length (m): 20 米 HG / T2183 dilute acid and alkali-resistant soft rubber Pipe | most professional acid hose | HG / T2183 resistant rubber hose Product Name:? HG / T2183 dilute acid and alkali-resistant rubber hose product structure: acid corrosion within EPDM synthetic rubber layer, fabric reinforced layer, spiral wire skeleton anti negative layer, wear-resistant outer layer anti-aging, PPH, or other acid plastic connector. Uses: acid transport or pumping liquid product advantages: the inner layer made of high quality EPDM synthetic rubber, than ordinary acid hose has better resistance to acid swelling and aging, the outer layer has better wear resistance may drag on the ground. Connectors using acid plastics manufacturing, compared to ordinary acid hose assembly of stainless steel fittings have a longer life. Category: A type (there are no fabric reinforcement layer spiral steel skeleton for transporting acid liquid) B type (with enhancement layer and has a steel spiral skeleton for attracting acid liquid) C type (with enhancement layer and has a wire spiral skeleton, soft tube than type B, for Suction acid liquid) Product specifications:?
