CPVS Pipe Grade

CPVC pipe is produced from a specialty blend of chlorinated polyvinyl chloride material with unique physical properties desirable for piping applications (i.e., improved impact resistance and good fire resistance capabilities). Pipe grade CPVC product line includes schedules 40 and 80 piping from 1/4″ through 24″ diameters. CPVC piping systems can handle more than three-fourths of the temperature/pressure requirements of today’s typical process plants. CPVC pressure pipe has an upper working temperature limit of 200° F (93° C), or approximately 60° F (15° C) above that of Type I Grade I PVC. As with all thermoplastic piping systems, CPVC’s ability to withstand pressure varies with pipe diameter, wall thickness, and temperature. As the pipe diameter and temperature increases, the pressure rating of the product decreases. For example, 1/2″ Schedule 80 CPVC pipe is engineered for continuous service of 850 psi @ 73°F (23°C). The same pipe in service @ 180°F (82°C) carries a maximum working pressure rating of 210 psi at this temperature. 6″ Schedule 80 CPVC pipe is designed for 270 psi @ 73°F, and 54 psi @ 200°F.

PTFE Lined Pipe and Fittings

Use PTFE lined piping in any application where superior chemical resistance is required. Compared to other plastic pipe lining, PTFE has been proven to reduce permeation rates by up to 60%. It is also far more resistant to corrosion and high temperatures, and it features a full vacuum rating up to 450°F.

As a result, PTFE lined pipe and fittings are ideal for severe service applications, including pulp and paper processing, and power generation. Compared to exotic alloy materials or glass lining, PTFE is an economical choice that gets the job done right.

PTFE Lined Pipe

PTFE lined pipe provides unmatched chemical resistance at temperatures to 260ºC. Because its carbon chains are completely fluoronated, PTFE is chemically inert to the following broad range of commercial chemicals:

• All acids including hydrofluoric, hydrochloric, sulphuric and aqua regia
• Chlorides - organic and inorganic
• Sulphates - organic and inorganic
• Bleach solutions
• Solvents
• Phenols
• Caustics
• Peroxides

Combined with the chemical inertness of PTFE are its usual non stick properties. Thus a PTFE lined pipe system eliminates and/or minimises build up of deposits on the pipe walls, which otherwise would reduce flow and possibly affect processing operations.

PTFE Lined Pipe for chemical resistance at extreme temperatures

• Size range - 25 - 300 NB
• Steel Pipe - Welded or seamless, schedule 40
• Flanges - Any speciation (ASA 150lb STD)

PTFE lined pipe is suitable for water, acid, chemical, food, mining, petroleum, gas, medical and energy applications.

 

ptfe lined pipe, teflon lined fittings

Our PTFE lined & jacketed steel dip pipes and spargers are manufactured to the highest standards in the industry. All units are given extreme stress tests to validate their integrity and ensure long life.

PTFE is one of the most versatile materials used for lined pipe and fittings. It is near-universally chemically resistant and capable of withstanding temperatures as high as 450°F (230°C), making it ideal for handling nitric acid, oleum, nitrobenzene and other fluids used in industrial and manufacturing processes.

Choose a PTFE pipe fitting for pharmaceutical, food and beverage, and other applications where performance can’t be sacrificed in the name of cost savings.
