How much water can I get through my screen

One question I get asked reguarly is this.

“How much water can I get through my screen”?

This can be calculated, so I designed a online calculator on the web site that can easily help you
get the answer you need plus  there are charts where the calculation has been done for you.

The link to the calculator is

The Data sheet

http://deps.com.au/data-sheet-hidden-menu/open-area-slotted-pvc

Let me explain the difference between flow and velocity.

Flow is the amount of water coming through the pipe, the larger the pipe the more flow you can have.
can be expressed as “litres per second”

Velocity is the speed of the water flowing through the pipe.
Meters per second.

An Example is, if you are standing in front of a large pipe and the water is flowing out slowly, you could stand in front of this, and get knocked down possible, but if it flows at a great velocity
it would knock you down quickly and no chance of getting up.

A fire truck water hose has a lower flow but massively high velocity, this is why you will often see 2
fireman holding the hose, as it would fling one person.

If your slotting pattern or pipe size is not on the data sheet then please use the calculator.

In part 2 on this topic, which will be sent next week, we will look at the factors needed,
when designing the screen for your bore.

Bore Screen Names

It’s always hard for everyone when a product has more than one name and that name is also associated to a completely different product.

This is the case with bore screens, this specialized product in its standard formation , is made from UPVC pressure pipe and is slotted with horizontally around the pipe, standard slotting is 0.8mm wide slots with 10mm between the slots and between 3 and 8 rows around the pipe.

 

Some of the different names and types, that people use, plus the different spelling are

Happy New Year

Hi

Wishing you a Happy and Successful New Year,

2015 is here and the pace of work Is slowly building up already.

When I was home enjoying the break, I was thinking about 2015 and what I needed to do and what I would like to do

I knew that I didn’t want to make any sill new year resolutions that get broken immediately, but I knew that I needed to change things to ensure that

My plans would happen.

 

How do you make a good plan when there is an event that could change your life and your not in charge.

 

It’s a bit like when a worker gets seriously hurt and you’re the manager, your life gets turned upside and possible Jail.

 

Next week I go to court over my Grandkids, and who knows what the judge will do, so until then my plans are put on hold.

 

This has not stopped me looking ahead and planning areas that I am still in  control off, In the next news letter which will be a Jan – feb issue

I will have some links to slides and handouts that will help you look at 2015 in a new way and may be change your thinking of setting goals.

Setting goals may be hurting you not helping you.

 

With DTH closing we are looking at ways to fill this hole that has been left by them and looking at better ways how we can help you.

 

If you have any specific needs please feel free to contact us and see if we can be of assistance to you.

 

Look out for our Australia Day specials coming soon

UPVC Vs MPVC & OPVC

The material called as MPVC comes from the PVC which is Ploy vinyl Chloride. It is mainly Modified Poly vinyl chloride. The product called UPVC stands for Unplasticised Poly Vinyl Chloride and the term OPVC stands for oriented poly vinyl chloride. First we would take the purpose the types of PVC pipes. The utilization of the MPVC is manly in small wall thickness attachments whereas the areas of high thickness and high stress areas like sewage lines etc. The UPVC is used as they are more durable and due to the absence of plasticizing polymers, which makes them quite tough to external deformations. OPVC usage has many specific areas as it is oriented poly vinyl chloride. They are also in use for the sewage systems as well at water distribution areas of municipal corporations and other areas. These pipes are almost 35% lighter and easier to handle than general PVC pipes and quite easy to maintain. MPVC is fundamentally a thermoplastic alloy with additions of modified agents to increase the physical properties like ductility and toughness. It has been developed in recent years and has got wide applications in high pressure industrial applications, irrigations and water purification. These pipes do hold the structure and properties of PVC and with that added agents. When taking UPVC into account its physical structure and production procedure is same as any other PVC, but only thing is that as in case of PVC in the end it has not been softened by plasticizing which makes it tough for any impact. Basically because of its ability not get biologically decomposed, reshaping at high temperature (easy recycling) and stable under normal climatic conditions. They found immense applications at the conservatory manufacturing industry. It is also used in windows and door manufacturing. The thermoplastic capabilities of UPVC make it suitable for 10,000 applications in different forms. Now coming to OPVC and its differences from other two in terms of manufacture and structure is that while it is made, it is made by realigning the PVC molecules by means of biaxial orientation. The thickness gets reduced to up to 45% and the greatest physical enhancement that it gets is of its impact resistance which increases eight times. The strength also gets doubled. These pipes  have large bore capacity with increased hydraulic capacity. The use of OPVC has been increased in several folds in last seven years and has taken over UPVC. Whereas the leader in the market remains the MPVC which has got the highest spread of applications worldwide. In terms of Eco friendly factor,  OPVC cleans sweeps off other two as it has been proved that the future of PVC types lies with OPVC as they are most Eco friendly pipes available. Some of the other features of OPVC which makes them stand alone are its high corrosion resistivity, light weight, smooth bore with lowest frictional losses, high strength and recyclable. Whereas the currently existing  market, maximum used PVC pipes known as MPVC gives resistance to cracking, and low level stresses only which are not enough for current market. The use of UPVC has been in the rise for last ten years and almost equal and in some cases higher than use of MPVC because of its chemical resistivity, fire resistance and hygienic properties that it maintains. The first change of sewage system pipes from cast iron pipes to UPVC pipes have proved of be of significant help in every sphere. Indeed all three OPVC, UPVC and MPVC have its own importance and specific areas of application even though the future of piping lies with UPVC and OPVC pipes.

UPVC is the type of pipe that is used in the drilling sector because of its core strength as described above

Case Study 48 – Trench Drains

Trench drain is an effective as well as popular solution for evacuation of surface water, chemical spills and utility lines. It will function for a long time and generally referred to as channel drain, line drain, slot drain, linear drain or strip drain. Trench drains offer multiple advantages and they are available in wide number of varieties in the market. The best trench drains have economical cost, easy installation and long-lasting performance with little to no maintenance. They are specially designed to provide durability, performance, reliability, and trouble free water evacuation process, where water clogging is maximal.

It is specific drain type, which consist of main channel shaped body utilized in drawing water quickly without clogging and jamming on the land surface. It is made of solid coating or grating cover that has long length and narrow width. The land surface is slightly inclined towards the trench drain so that the process of evacuation of water is quick and without any clogging.

DEPS trench drains

DEPS trench drains

The trench drain is available in multiple sizes that should be bolted together to lay down complete system. The process of installation is rapid, simple and unproblematic. The best thing about the trench drain is that it doesn’t require multiple sloping and since it runs all along the sideways of the ground, there is 100% probability that water will never clog and choke. One thing to keep in mind during installation is to position the drain in trench and make footer, form as well as grade with only one pour. These will definitely saves you money, time and resources. The anchor stand will make installation easy and allows easy grade adjustments.

There are many types of trench drains like cast-in-place, pre-cast concrete, liner systems, former systems, fiberglass, plastic, radius drains, custom drains and stainless steel. They are resistant to rough, coarse and acidic liquids whether it is in residential or commercial areas. The interior surface of the trench drain smoothly drains the water and keep it clean and unsoiled.  Their applications are extensive, widespread, and used particularly for its easy drainage system whether it is for residential purpose or commercial purpose. The diverse types of Trench drains are extremely useful for different purposes. These features make trench drains an excellent choice in managing surface drainage.

Trench drains are used in airport, swimming pool, roads, highways, kennel, industries, manufacturing units,  factories, car dealership units,  residential areas, fire stations, sports complex, stadiums, arenas, docks,  trucks garage, hospitals, pedestrian walkways, parking lots, garages, schools, waste water treatment plants, car wash centers, food processing units, gas stations, kitchens, utility centers, laboratories, veterinary hospitals, landscapes, fountains,  shops, gasoline stations, and many more places. They are usually mistaken as French drains and slot drain that are buried in gravel bed and opens at surface of the ground respectively. Nevertheless, they are best and effective drains for surface drainage system.
