In harsh industrial scenarios such as fine chemical industry, pharmaceutical synthesis, and hazardous chemical transfer, the stable conveying of strong corrosive fluids has always been the core challenge of the pipeline system. After long-term contact with concentrated acid and alkali, strong oxidants, and various organic solvents, ordinary rubber pipelines are prone to failures such as colloidal swelling, inner wall scaling, and aging cracking, which will not only cause medium leakage losses, but also may lead to workshop safety hazards. LETONE PTFE acid and alkali resistant rubber hose DN25 adopts polytetrafluoroethylene lining as the core, matched with a composite reinforcement structure, and has become the mainstream chemical corrosion-resistant conveying hose solution that combines strong corrosion resistance, high temperature resistance and high reliability in chemical scenarios.
Core Structure of PTFE Acid and Alkali Resistant Rubber Hose with Full-Medium Corrosion Resistance
This DN25 specification LETONE PTFE acid and alkali resistant rubber hose adopts a three-layer composite structure design, and each layer from the inside to the outside is specially optimized for chemical conveying conditions:
- The innermost layer is a high-purity polytetrafluoroethylene (PTFE) lining. Except for molten alkali metals and elemental fluorine, it can resist almost all strong corrosive media, including aqua regia, concentrated nitric acid, strong concentrated alkali, aromatic organic solvents, etc. It will not have medium erosion and penetration problems at all, and it is a real chemical corrosion-resistant and high-temperature resistant conveying hose
- The middle reinforcement layer adopts a multi-layer high-strength and high-flexibility steel wire braided winding structure, which greatly improves the pressure-bearing capacity of the hose. The conventional rated working pressure can reach 1.0-1.6MPa, which is suitable for the positive pressure conveying requirements of most chemical fluids
- The outer layer is a special synthetic rubber resistant to ozone and wear, which can resist oil erosion, mechanical friction and outdoor aging in the complex environment of the workshop, and greatly extend the outdoor service life of the pipeline.
DN25 Specification Perfectly Adapts to Mainstream Chemical Conveying Scenarios
The size design of DN25 nominal diameter makes this LETONE PTFE acid and alkali resistant rubber hose have extremely high scenario adaptability:
- The standard length of a single hose can reach 6 meters, and the short-distance process pipeline layout in the workshop can be completed without too many intermediate joints, reducing leakage risk points
- The flow performance is stable, and it can achieve 5-10 cubic meters of fluid conveying efficiency per hour under conventional working conditions, which perfectly matches the process links such as feeding of small and medium flow chemical reactors, waste liquid transfer, and chemical agent adding
- The minimum bending radius is only 250mm, which can easily bypass the corners of workshop equipment and frame obstacles, and complete the pipe routing in compact space without hard bending.
Wide Temperature Range Long-Term Operation Advantages of Chemical Corrosion-Resistant and High-Temperature Resistant Conveying Hose
Different from ordinary corrosion-resistant hoses, this DN25 PTFE acid and alkali resistant rubber hose has a long-term working temperature range from -60°C to +200°C, and the short-term peak temperature resistance can reach 260°C. It is fully adapted to the intermittent chemical production conditions with alternating cold and hot. Even when conveying high-temperature corrosive fluids, the lining layer will not bulge or delaminate. The PTFE material has a smooth inner wall and no adhesion, and the fluid friction resistance is extremely low. No medium scaling will remain in the hose after long-term use, which is especially suitable for the transportation of high-purity fine chemicals to avoid the medium being contaminated by pipeline impurities.
Model Selection and Operation and Maintenance Specifications for Chemical Scenarios
For the special chemical usage environment, the model selection and daily maintenance of LETONE PTFE acid and alkali resistant rubber hose DN25 must follow the core specifications:
- When purchasing, clarify the DN25 nominal diameter, adapted conveying medium, rated working pressure and operating temperature parameters. Prioritize finished hoses that have passed the 3-time burst pressure test before leaving the factory, and support special corrosion-resistant flange joints
- During daily use, avoid the outer rubber of the hose being scratched by sharp hard objects, regularly check the aging state of the PTFE lining layer, and replace the pipeline in time when there is a trace of medium precipitation and penetration
- Before replacing the conveying medium each time, rinse the inner cavity of the hose with a compatible solvent to avoid accidental reactions between different strong corrosive media in the hose.
Under the background of continuously upgrading chemical safety production requirements, this Liton PTFE acid and alkali resistant rubber hose DN25 has become a cost-effective upgrade choice for chemical enterprises to replace traditional ordinary rubber hoses and plastic-lined pipes by virtue of the core advantages of full-medium corrosion resistance and stable operation in a wide temperature range, building a solid safety line for the strong corrosive medium conveying link.
