Standard and Customized Lined Pipe and Fittings
The right choice of piping and fittings plays a key role in the success and efficiency of your processes. When it comes to fluid handling, manufacturers today have a larger number of options available to them than ever before. Working with a supplier you can turn to for expert advice is the best way to choose the combination of products that will offer the best performance in your application. External pipe material is available in carbon steel or stainless steel.
SEMCOR carries off-the-shelf standard pipe fittings and piping in a wide range of materials, sizes, and configurations. We are also fully equipped to modify an existing product so that it performs better in your specific application. Follow the links below for more information about the pipe fittings products we offer our clients in the chemical processing, power generation, pharmaceutical and other industries.

PTFE-Lined Pipe and Fittings
Fluoropolymer (PTFE) or Teflon lined pipe and fittings offer exceptional resistance against corrosive chemicals, as well as superior flexibility and the ability to handle high-temperature liquids. SEMCOR is an authorized distributor of Baum and Resistoflex® PTFE-lined pipes and fitting products. We supply the companys’ complete lineup of PTFE-lined piping and accessories in sizes ranging from 1” to 12”. With the strength of steel and superior corrosion resistance, PTFE-lined piping is an excellent choice for many industrial applications. SEMCOR has one of the largest inventories of PTFE lined pipe and fittings in the entire Midwest and can fabricate pipe spools in-house that have up to a 10-inch diameter. Do you need field fabrication tools for your project? We have you covered for those as well. We have the lined pipe field fabrication tools for purchase or rent to meet your requirements.
Polypropylene (PP)-Lined Pipe and Fittings
Polypropylene (PP) lined pipe is our most economical option for industrial fluid handling. Polypropylene lining delivers excellent resistance to acidic and basic fluids and can handle temperatures up to 225˚F (110˚C). However, it does not handle solvents and VOCs well, and can become brittle in low temperatures. Typical uses for Polypropylene-lined piping include water treatment, chemical processing, and power generation. PP-lined piping is also a popular choice for use in food and beverage manufacturing, processing and packaging.
Baum PTFE-Lined Pipe and Fittings
Baum PTFE piping has been designed to reduce permeation rates by up to 60%. Made from specially formulated resins, Baum PTFE liners deliver optimal crystallinity and strength, even in severe service applications. As a result, they can withstand exposure to both aggressive chemicals and higher temperatures. For more information and detailed product specifications, contact SEMCOR directly.
PVDF-Lined Pipe and Fittings
PVDF lined pipe — also known as Kynar® lined pipe— is extremely tough and durable, with superior abrasion resistance compared to other types of lined piping. It has a high thermal expansion coefficient and is suitable for use with halogens and high-strength acids. As a result, PVDF-lined piping is often used for pulp and paper manufacturing, chemical processing and electronics manufacturing. Kynar is less suitable for processes involving pH levels higher than 11, or temperatures above 275°F (135°C).
Ceramic-Lined Pipe and Fittings
Ceresist manufactures ceramic lined valves, fittings, piping, orifice plates and custom engineered ceramic products. Ceramic products are designed for the most severe service applications by using corrosion and abrasion resistant ceramic materials.
Application Engineering and Material Selection
Choosing the right lined piping system requires a clear understanding of how process conditions interact with liner materials, external pipe construction, and connection methods. SEMCOR supports these decisions by helping facilities evaluate temperature exposure, chemical compatibility, permeation risk, abrasion potential, and mechanical stress. This guidance is especially valuable for operations that handle aggressive media or operate under variable thermal conditions. By aligning material selection with real world operating demands, facilities can improve system stability and reduce long term maintenance needs.
System Integration and Connection Planning
Lined piping systems must integrate smoothly with pumps, valves, tanks, and instrumentation. SEMCOR assists customers in reviewing flange types, gasket materials, bolt torque requirements, and spool lengths to help ensure proper alignment and sealing. This planning helps prevent issues such as liner pull out, uneven compression, or premature wear at connection points. Proper integration also supports smoother installation and reduces the likelihood of rework during commissioning.
Lifecycle Management and Inspection Strategies
Lined piping systems are designed to withstand challenging environments, but long term performance still depends on proactive maintenance. SEMCOR helps customers develop inspection strategies that include visual checks for blistering, liner deformation, permeation indicators, and external corrosion. Understanding how different liner materials behave over time allows teams to schedule service before performance declines. This approach supports better budgeting, fewer unexpected shutdowns, and improved reliability across fluid handling systems.
Frequently Asked Questions
What Factors Influence Lined Pipe Selection?
Media type, temperature range, permeation risk, abrasion potential, and system layout all play a role in determining the right lined piping solution.
How Can Facilities Extend the Life of Lined Piping Systems?
Regular inspections, proper installation, correct gasket selection, and monitoring of operating conditions help maintain long term performance.
