PTFE Lined Industrial Chemical Process Receiving Tank

PTFE Lined Industrial Chemical Process Receiving Tank is a dedicated intermediate collection vessel independently developed by Zhuoyan factory in China, exclusively supporting continuous chemical synthesis and rectification production lines. Different from large-volume raw material storage tanks, this receiving tank features small compact volume, fast medium transfer interface and stable vacuum bearing capacity, specially used to temporarily collect high-corrosion distillate, condensed liquid and reaction effluent generated in front-end reactors and distillation towers.

The integrated seamless PTFE lining avoids medium cross-contamination during switching production batches, and standardized flange sizes realize quick docking with various fluorine lined process equipment. It is widely matched in fluorochemical, pharmaceutical and new energy full-set production systems, with stable delivery records to Southeast Asian and Middle East chemical factories.

What is PTFE Lined Industrial Chemical Process Receiving Tank

PTFE Lined Industrial Chemical Process Receiving Tank is a small-to-medium pressure buffer vessel with carbon steel shell and seamless sodium-activated PTFE inner lining, specially set at the outlet end of reactors and distillation columns in closed chemical process lines. Its core function is instant receiving, temporary buffering and transition conveying of high-temperature, acid-base and fluorine-containing condensed media. Compared with general storage tanks, it has multi standard process nozzles reserved at top and side walls to match feeding, vacuum pumping, sampling and liquid level detection pipelines. The whole tank adopts no-dead-angle lining design to prevent residual medium from causing cross-batch pollution, and the structure is optimized for short-cycle continuous production switching, perfectly adapting intermittent and 24h cyclic industrial process working conditions.

Core Competitive Advantages

· Dedicated Process Matching Multi-Nozzle Design Reserved vacuum port, sampling port, liquid level port and discharge port at fixed positions, realize one-time docking with distillation column, condenser and lined pipeline without secondary transformation, greatly shorten production line installation cycle.

· Stable Negative Pressure Adaptation For Distillation Integral vacuum pasted PTFE lining closely attached to steel shell, can run stably under -0.09MPa long-term vacuum distillation environment, no lining bubbling or peeling risk during medium condensation.

· Compact Small-Volume Layout Adaptation 50L-3000L mainstream volume range, small floor space, can be installed on platform brackets above equipment without occupying large factory ground storage area.

· Zero Dead-Angle Lining To Avoid Medium Residue All inner wall corners, nozzle welding positions are fully wrapped by seamless PTFE material, no hidden medium retention gaps, effectively guarantee high-purity production standards for pharmaceutical and electronic chemical projects.

· Fast Batch Switching & Easy Cleaning Smooth inner PTFE surface reduces medium adhesion, quick discharge bottom structure shortens tank cleaning time between different formula batches, improve overall production efficiency.

· Unified Standard Interface System All flanges adopt HG20536 anti-corrosion unified standard, can be interchangeably matched with Zhuoyan full series PTFE lined reactor, column and pipe fittings, realize one-stop supporting procurement.

Professional Model Selection Suggestions

1.Select Volume Based On Production Cycle

Short-batch frequent switching process: choose 50L-500L mini receiving tank; 24h continuous rectification production line: adopt 1000L-3000L medium size model to reduce discharge frequency.

2.Select Lining Thickness According To Medium Property

Ordinary acid, organic solvent: 3mm standard PTFE lining; hydrofluoric acid, fluorinated condensate medium: upgrade to 4mm thickened seamless lining.

3.Vacuum Working Condition Matching

If the distillation system runs under long-term vacuum below -0.07MPa, inform our technical team to strengthen tank lining vacuum bonding process.

4.Matching Equipment Interface Confirmation

Provide the flange size and nozzle quantity of your front reactor/distillation column, we adjust receiving tank nozzle layout for free to realize seamless docking.

5.Installation Environment Differentiation

Platform suspended installation: supply light-duty fixed bracket accessories; ground independent placement: thickened anti-slip base structure customized.

Whole Production & QC Inspection Flow

· Steel Shell Precision Machining Full polishing of all nozzle and tank body welding seams, high-temperature degreasing to eliminate internal welding stress, avoid lining delamination caused by thermal deformation.

· Sa2.5 Grade Standard Sandblasting Uniform rough treatment on inner wall to maximize PTFE sheet adhesive force, ensure long-term vacuum operation stability.

· Sodium Activation Vacuum Lamination Import PTFE sheet after special activation treatment, vacuum seamless pasting in 10,000-grade clean workshop, double PFA welding at all nozzle joints.

· Full Wall 10KV Spark Scanning Inspection Inspect every inner corner and nozzle lining position one by one to find tiny lining gaps that may cause medium leakage.

· Hydraulic Pressure Holding Test 1.2 times design pressure water pressure test, keep pressure for 30 minutes without pressure drop to confirm overall tightness.

· Finished Cleaning & Protective Packaging Remove workshop residual dust inside tank, seal all nozzles with PTFE protective caps, adopt reinforced wooden case for sea transportation.
