SIGNOR PIPE CORPORATION (SPC) is a well-known manufacturer in the industrial, municipal, agricultural/irrigation, domestic pipe markets.
Proper raw materials with specified grades (PE63, PE80 & PE100) are selected for production and these polyethylene are polymerized in controlled environment thus producing PE pipes of high quality products, superiority on nature. Polyethylene (PE 100) pipes can carry potable water, waste water, slurries, chemicals, hazardous wastes, & compressed gases. In fact PE-100 is strong, extremely tough and very durable when compared to it preceding materials like PE-80, & PE-63 Grade. PE-100 Pipe has superior qualities in terms of mechanical and also other properties when compared to PE-80 & PE-63. The polyethylene material used for the manufacture of pipeline systems are classified and dimensioned by long term performance under hydrostatic pressure in accordance with IS 4984:2016. The design basis used in IS 4984:2016 for Pressure rating (PN) of PE Pipes in order to determine the minimum wall thickness for each diameter and PN rating provides for the steady and continuous application of the maximum allowable working pressure over an arbitrary period of 50 years. The selection of the long term hydrostatic design stress values (HDS) is dependent on the specific grade of PE and the pipe material service temperature.
The inherent flexibility of the HDPE Pipes provides this product with its inherent minimum pipe stiffness of 320 kPa or 210 kPa. The smooth inner wall provides longitudinal stiffness which enables alignment and grade to be maintained in the trench during installation.
HDPE Pipe contains a minimum of 2% carbon black additives to protect the product from ultraviolet light. This gives HDPE Pipe maximum weather resistance in applications where continuos exposure to the elements is expected.
HDPE has the highest level of chemical resistance of all traditional sewer products. HDPE pipe brings the gravity flow sewer market the same exceptional performance remaining tough and resistant under conditions that could seriously damage pipe made of other conventional materials.
HDPE material provides excellent resistance to both acidic and alkaline environments with strong acids through all base, ranging PH 1.25 to 14.
Tests indicate that HDPE Pipe is highly resistant to abrasion, giving it a significant advantage over other pipe materials in both acidic and abrasive environments. Piping made from polyethylene is a cost effective solution for a broad range of piping problems in municipal, industrial, marine, mining, landfill, duct and agricultural applications. it has been tested and proven effective for above ground, surface, buried, slip lined, floating and sub-surface marine applications.
Polyethylene Pipe & fittings are inherently tough, resilient and resistant to damage caused by external loads, vibrations and from ressure surges such as water hammer. even in cold weather polyethylene pipe is tolerant to handling and bending.
The design and construction of HDPE product offer a distinct weight advantage over conventional pipe. They Provide ease of handling, positioning, installing and connecting those conventional pipes cannot match. HDPE pipe affords these important ben-efits to the user.
Due to its light weight, less manpower and lighter machinery is needed to transport, handle & connect HDPE pipe compared to most of the other pipes. That’s real saving and real value added by using HDPE pipes.
PE pipe is highly resistant to the rigors of installation handling in tough environment prevailing at the site location. HDPE pipe can be installed with confidence in the hottest of summer or the coldest of winter conditions.
