PTFE Lined Chemical Storage Tank

If you need long-term safe containment of multi-component corrosive chemical raw materials, Zhuoyan factory’s PTFE Lined Chemical Storage Tank is your ideal storage solution. Different from single-acid dedicated storage vessels, this series tank is engineered to adapt alternating acid & alkali stockpiling, mixed fluorine-containing solvent temporary storage and large-batch industrial raw material inventory management. The integral seamless PTFE lining eliminates hidden leakage risks at tank bottom and flange connections, which frequently occur on cheap lined storage tanks with spliced lining layers. We provide vertical ground type and horizontal saddle type two mainstream structures to match different factory workshop height and ground layout requirements.

What Is PTFE Lined Chemical Storage Tank

PTFE Lined Chemical Storage Tank is a carbon steel pressure storage vessel integrated with seamless sodium-activated PTFE inner lining, specially designed for mass storage of various corrosive industrial chemical raw materials, semi-finished intermediates and waste liquid buffer materials. The high-strength Q345R steel shell provides stable mechanical support for long-term static storage, while the inert PTFE liner isolates all kinds of corrosive media from metal shell erosion. Unlike PFA sprayed storage tanks with thin coating easy to wear, our plate-lined PTFE layer has thick uniform thickness, resisting long-term static medium soaking. Standard volume covers small lab buffer 100L up to large chemical park 100000L storage specification, working temperature range -180℃~260℃, supporting atmospheric and slight negative pressure storage working conditions.

Core Unique Advantages For Chemical Storage Projects

· Integral Seamless PTFE Plate Lining Technology Whole tank inner lining adopts one-piece large PTFE sheet vacuum lamination, only minimal V-type welding at manhole, greatly reduce medium penetration risk compared with segmented spliced lining of small manufacturers.
· Wide Medium Compatibility For Mixed Chemicals 3–5mm adjustable thick PTFE liner can bear alternating storage of acid, alkali and organic mixed media, no need to replace different tanks for various raw materials, cut total storage equipment procurement cost.
· Complete Matching Lined Pipeline System Support one-stop purchase of PTFE lined elbow, tee, valve and discharge pipe, realize fully closed anti-corrosion storage & conveying system without medium leakage.
· Strict Full-Process Anti-Leak QC Standard Each tank goes through sandblasting roughness inspection, high-temperature degreasing, full-wall 10KV spark scanning and hydraulic tightness test before leaving factory, zero hidden lining leakage risk.
