, oils and chemicals has witnessed many gloomy stories of several tragic accidents. With the PTFE Flange Guards the valves and pipelines are safeguarded to save the world from uncertainties caused by the leakage of all the hazardous materials.

Used widely for sealing the joints as to prevent the leakage they are Pvc flange spray shields. For the flawless application throughout every industry and each time they are available in different sizes and materials.

Whether it is the leakage of the chemicals or water Leakage is the most common problem of every industry.

Fighting back especially when you are operating with the hazardous chemicals is necessary with the leakage of the chemicals.

Widely used to prevent the leakage of the gases, oils, and liquids Flange Guards and Gaskets are the products from the huge range of the products. With various materials the gaskets are available in the market as per the application of the product.

, spray outs and mist formation.

While keeping the liquid flowing inside free from the contamination they are excellent at protecting the same against the dust formation, dirt and corrosion apart from protecting the joints from leakage.

For fantastic heat and chemical resistance The PTFE products are known. Using the PTFE material to exceed the application to provide the industry shielding guards, the engineers work harder to design a product.

, mist formation and leakage the Ppl flange spray shields are installed at the flange joints, pipelines and valves etc.

Due to the high concentration of the chemicals further protects the joints and the environment from the formation of rust and harmful chemicals they seal the joints perfectly. Formation of rust as well as the chances of failure is avoided by the regular maintenance.

Against temperatures and load The PTFE has excellent tolerance, which even under the extreme pressure keeps the product unaffected by the chemical. While keeping the liquid flowing inside and the environment safe the barrier between the outer and inner wall prevents the liquid from coming out.

A PH indicator In PTFE Flange Guards

The PH indicator to detect the leakage easily comes with the product. Dangerous circumstances may be the outcome of some moments when the user failed to install the product perfectly but the situations can be tackled better by a PH indicator.

We have all heard of a leap year - that extra day added to the calendar every four years. It may give us a longer February but it is also essential in keeping our calendars and seasons accurate. If the extra day is not added to a leap year then eventually (admittedly after over a century) the Winter will begin in July and the summer will start around Christmas (and vice - versa in the southern hemisphere) because the Earth takes an extra six hours longer than the 365 days of a year to circle the sun.


A leap year may be a bit of a fudge but the alternative would be to have a quarter day at the end of the year which would of course throw our days and nights out of sync with each other (and could you imagine just having a six hour day - some of us struggle to get things done in 24!).


We have of course always measured time in relation to the movement of the Earth - a day being an entire revolution

, a year an orbit of the sun. However, as our way of measuring time became more and more accurate it soon became apparent that there were more irregularities in the Earth's rotation than just the extra six hours in a year.


GMT (Greenwich Mean Time) was developed because there was a need for a time scale where the mean position of the sun at noon, averaged throughout the year

, is above the Greenwich Meridian (zero longitude) and daylight saving hours are added or taken away depending on the time of year.


However, in 1955 the first atomic clock went into operation following the discovery of the stability of the caesium-133 atom which vibrated at an exact rate (9,192

,631,770 a second). Impressed with this accuracy, The International System of Units of Measurement (SI) decided that a second should be defined as this number of oscillations of the caesium-133 atom.


Following the SI second a time scale called International Atomic Time (TAI - from the French Temp Atomique International) which was a simple count
