User industries

Pharmaceutical:
Uni Polymers supply equipment to all the main Pharmaceutical companies in the India. Large scale project supply has seen the completion of several pharmaceutical manufacturing plants with all the lined piping and valves being supplied by Uni Polymers.
Crop Science :
The production of biocides, fungicides, herbicides and insecticide involves the use of highly corrosive chemicals, Uni Polymers have supplied large amounts of HDPE /PP / PTFE lined piping and valves to these manufacturers.
Water Treatment :
Chemicals such as Chlorine and Sodium hypochlorite are extensively used in water treatment plants. Whilst these are diluted significantly with the water, the pure chemical holding and injection / mixing lines are subject to corrosion. Our range of HDPE / PP and PTFE Lined Pipes have been supplied into these applications
Chemical Manufacturing :
Many chemical manufacturers use Uni Polymers lined piping products in their facilities, feed stock chemicals such as, sulphuric acid, nitric acid etc are all corrosive and require the use of corrosion resistant piping HDPE / PP/ PTFE lined piping is the ideal solution
Cleaning and Detergent Products :
Chemicals used in cleaner and detergents can derive from very corrosive and toxic chemicals, our HDPE /PP/ PTFE lined piping has replaced many bare polypropylene and other thermoplastic piping systems which have prematurely failed on these applications.
Fine Chemical Manufacturers :
Manufacturing of chemical substances for use in manufacturing drugs, commonly called APIs (active pharmaceutical ingredients) often involves the use of highly corrosive substances.HDPE / PP / PTFE lined pipes are widely used to convey such substances, it is FDA approved and is easily cleanable.
Process Plant Manufacturers :
Uni Polymers can help with the design and specification of components required in the manufacture of process skid units, process packages etc. utilizing HDPE, PP and PTFE lined products. Our piping products and valves are often used around specialist components such as filter assemblies, dryers, scrubbers etc.
Power Stations :
Fossil fuelled power stations can suffer a variety of corrosion issues, the steam and cooling water requires treatments which can corrode steel piping and valves. By using HDPE / PP /PTFE lined pipe and valves on these applications prevents the corrosion of the equipment.


 

Our Details

The Unique Process

Pipes:
The lining process for Pipes positively locks the plastic liner in the metal pipe housing while effectively relieving stresses that could cause unwanted liner movement in service.
The liner is processed under controlled conditions to a size somewhat larger than the I.D. of the steel housing into which it will be installed. It is then thoroughly inspected for conformance to specifications. Next, the liner is subjected to a battery of quality tests designed to ensure liner integrity.
The liner is then drawn through a sizing die at carefully controlled draw rates which results in a calculated reduction in the outside diameter.
A programmed heating cycle relaxes the liner inside the steel housing, resulting in a snug liner fit.Design allowances are incorporated in this procedure to eliminate undesirable stresses in the finished product.
Both liner ends of the pipe spool are then hot flared. Temperature, time and pressure are carefully monitored.
The finished pipe is then tested in accordance with ASTM F1545 standards.
This unique lining process provides lined pipe with dimensional stability under vacuum, pressure, and thermal cycling conditions, which prevents liner buckling and cracked flares within operational limits. Fittings: All fittings are lined by automated Transfer/Injection moulding process. Our in house tooling facility insures uniform lined wall thickness.

Inspection and Tests

Hydrostatic Pressure Test: All Piping products are tested for 150 % of maximum recommended working pressure. Test pressure reaches in 1 minute and maintained for 3 minutes.
Electrostatic Test: All Lined products are tested with non-destructive high voltage tester at an output voltage of 10 Kv. to detect lining integrity or pin holes.
Visual Inspection: All finished products are visually inspected for any spots or cracks.
External Finish: All pipe and fittings are coated with Red Oxide OR as per customer specifications with an extra cost.
Note: Other customer-specified coatings are available. Upon review of the data sheets of the requested paints, however, Uni Polymers reserves the right to decline quoting customer-specified coatings based on MOC content, manufacturing incompatibility, or other factors.
Note: Normal shipping and handling can cause paint damage that requires touch-up at the job site. Costs associated with paint touch-up are for Buyer's account.
