Tirupati Plastomatics Pvt. Ltd. had conducted System Approval Tests specified in Indian Road Congress (IRC:18-2000) and Fib. Bulletin-7 on Gemini Brand HDPE Sheathing Duct manufactured by them for assessing co-efficient of friction, wobble co-efficent, Bond Behaviour, Wear Resistance Properties of duct. These test were carried out by Indian Institute of Technology (I.I.T)-Mumbai, the most competent institute of India for Heavy Structures & Civil Engg. in November & December-2011 and the test results obtained are best in the industry. These test were witnessed by officials from DMRC, Jaipur Metro, MMRDA, Freyssinet Menard, ITD-ITD Cem JV, Simplex-Mumbai and consultants like Consulting Engg. Services, etc.

Tirupati Plastomatics Pvt. Ltd. has executed export orders from Oman, Nepal & African countries like Ghana during 2011-2012 for its Double Wall Corrugated Pipes & HDPE Sheathing Ducts.

For Underground Communication and Power Cable Protection, the IS specification is IS 14930 (Part I and Part II). In comparison of Double Wall Corrugated HDPE Corrugated Pipes vis-à-vis PVC pipes and Plain HDPE Corrugated Pipes, by perusing these comparatives, the differences between Plain HDPE Corrugated Pipes and Double Wall Corrugated HDPE Corrugated Pipes conforming to IS14930 could be appreciated.

The Units like Tata Power, Brihanmumbai Electric Supply and Transport Co. have switched over for utility cables from IS 4984 of 1985 (specification of ducts for potable water) of Plain HDPE Corrugated Pipes to IS 14930 (Part I and Part II) (specification for underground cable protection duct) of Double Wall Corrugated (DWC) pipes as Double Wall Corrugated HDPE Corrugated Pipes are superior to Plain HDPE Corrugated Pipes.

It will be interesting to note that plain HDPE Corrugated Pipes are costlier than Double Wall Corrugated HDPE Corrugated Pipes. In these circumstances, the merits of Double Wall Corrugated HDPE Corrugated Pipes must be considered in place of PVC pipes and Plain HDPE Corrugated Pipes.
