Why Vessel Accessories Matter for Your Piping System
Vessel accessories bridge the gap between piping and process equipment. In many chemical, pharmaceutical, and industrial plants, plastic-lined piping systems handle corrosive acids, solvents, or other aggressive fluids that would quickly degrade metal surfaces. By extending the same protective fluoropolymer lining into tanks, reactors, and vessels, these accessories create a seamless barrier from one end of the system to the other.
Properly engineered vessel accessories provide several advantages:
- Maintain corrosion protection from the pipe to the process vessel
- Reduce contamination in sensitive or high-purity applications
- Prevent costly downtime caused by leaks or material failures
- Improve product consistency and process efficiency
- Simplify installation and long-term maintenance
Whether you’re designing a new system or upgrading existing process equipment, selecting the right vessel accessories helps your investment in lined piping perform as intended throughout its service life.

Dip Tubes
Dip tubes are used to deliver or withdraw fluids below the liquid surface inside a tank or reactor. When lined with PTFE, PFA, or other fluoropolymers, they provide exceptional chemical resistance even under harsh process conditions.
Marspec provides you with dip tubes are engineered to match the lining material and dimensions of your piping system, minimizing the risk of chemical attack or mechanical incompatibility.
They are frequently used for:
- Introducing reactants into vessels
- Sampling process liquids
- Draining tanks without exposing internal metal surfaces
- Preventing splashing or vapor formation during fluid transfer
By integrating lined dip tubes into your process vessels, you maintain consistent corrosion resistance and reduce the risk of cross-contamination between materials.
Spargers
Spargers are vessel accessories that disperse gas into liquid, creating a fine bubble stream for mixing, aeration, or chemical reaction. In corrosive environments, unlined metal spargers can deteriorate rapidly. Plastic-lined spargers—often PTFE-lined or constructed entirely from fluoropolymers—offer a durable, non-reactive alternative.
Typical applications include:
- Gas dispersion for neutralization or oxidation
- Mixing processes in chemical manufacturing
- Aeration in biological or wastewater systems
We supply spargers designed to integrate seamlessly with lined piping connections, ensuring uniform gas distribution while maintaining complete chemical compatibility throughout the system.
Nozzle Liners
Nozzle liners protect vessel nozzles, manways, and inlets where pipes connect to the vessel wall. These areas are often exposed to high flow rates, turbulence, or direct impact from process fluids—all of which can accelerate corrosion.
A properly installed nozzle liner extends the fluoropolymer barrier from the pipe into the vessel, maintaining full corrosion protection across the connection. Marspec offers a range of materials and configurations to suit different vessel types and operating conditions.
Benefits of lined nozzles include:
- Continuous corrosion barrier between vessel and piping
- Extended vessel lifespan and reduced maintenance
- Simplified retrofit options for existing equipment
Reactor Sampling Systems
Reactor sampling systems allow operators to safely extract representative samples from vessels without interrupting production or exposing personnel to hazardous materials.
In lined systems, sampling points must maintain full corrosion resistance and prevent contamination. Marspec supplies components that integrate smoothly with PTFE-lined or PFA-lined piping systems, allowing consistent material performance across the entire process line.
Common uses include:
- Quality control during chemical reactions
- Monitoring of batch consistency in production
- Verification of concentration or purity levels
By using properly lined sampling systems, you can achieve accurate results without risking product contamination or corrosion-related leaks.
Tank Bottom Valves
Tank bottom valves provide a clean and efficient way to drain vessels completely. When lined with fluoropolymers, these valves maintain full chemical compatibility with the rest of the system, preventing corrosion and product buildup at one of the most critical points in the process.
Marspec offers tank bottom valves designed for:
- Full drainage of corrosive or viscous materials
- Integration with lined piping and vessel connections
- Easy cleaning and maintenance
They offer smooth operation, minimal dead space, and long-term reliability—making them ideal for demanding process environments where uptime and cleanliness are priorities.
