Information / Plastic or cast iron hatch?

Plastic or cast iron sunroof?

Let’s first go back to the question – “Why is a sewer hatch necessary?”
First of all, ensure road safety. Secondly, create access to the communication system and last for many years.

What is the advantage of polymer-sand hatches? Probably only because of their cheapness. Therefore, if your choice fell on a plastic hatch, then remember the expression: “The miser pays twice.”

Of course, in parks or in green areas, you can resort to installing polymer-sand hatches. But, as practice shows, an unpleasant circumstance can arise here too. After all, a pedestrian’s sharp heel can easily get stuck in such a lid, or at worst, the kids will break through the lid with a stone. Let’s keep silent about the quality of the installation.
Contractors who purchase plastic hatches do not think about safety; their direct desire is to save money.

The superiority of cast iron is obvious. Firstly, it will last a long 20-30 years. This will significantly save your budget compared to polymer-sand hatches, which at first glance seem many times cheaper. Secondly, they fulfill their intended purpose according to GOST.

The NurKazMetal plant produces cast iron sewer manholes in accordance with GOST standards. Each product undergoes strict certification.

Rain receivers. And is it really necessary?

Unfortunately, the construction of storm sewers is impossible without installing storm wells. So, according to the SNIP norms.

Basically, the storm water inlet is located in the courtyard of a high-rise building, on a park alley, along the sidewalk and pedestrian crossing, of course, if there is an autonomous sewer system. Also on the road along the path of the storm routes.
The devices are manufactured in the form of gratings. This is done with the intention that large debris will linger on the surface of the roads. This way the drain will not become clogged.

You may have a question: “What is the advantage of cast iron rainwater inlets?”

It was not in vain that we, as manufacturers, chose this particular metal, since it compares favorably with other materials.
At least because it can withstand any load class and has excellent throughput. Cast iron is a pure alloy, so we can easily characterize it with the word “environmentally friendly”. It is resistant to acid-base environments and will last for decades.

Our plant produces both round and rectangular types of rainwater inlets:

  • Round

Universal. The cover is easy to remove. You do not need to dismantle the well to clean the drain. You can install it: on the highway, and along the road, in the park, in the square, and even in the yard.

  • Rectangular

The design is in demand when it is necessary to accept huge volumes of wastewater. For example, in regions where there is a lot of rainfall.

Information / Iron casting

Cast Iron casting

Cast iron is an alloy of iron with a carbon to carbon ratio of at least 2.14%. Mostly metal is divided into 2 types: gray and white. In the first, the silicon and graphite content is from 2.9 to 3.7%.

On the main page, we have given a sequential description of the stages of work.
Here, we want you to familiarize yourself in detail with the basic methods of iron casting:

Casting in molds from a clay-sand mixture;
Gypsum, or shell form;
Metal protected form;
Under pressure;

Inside the mold itself, we place a model of the finished product, which repeats it, but is larger in size according to the amount of casting shrinkage.
The mixture is compacted and compacted so that it completely adheres to the model. Next, we carry out casting through the holes (sprues).

Products made of high-strength cast iron are produced using the method of casting into a gasified model, using molds from a sand mixture.
In order to improve its properties, high-strength cast iron undergoes heat treatment:

We heat the material to 850 °C;
We keep it warm for several hours;
Let cool with mineral oil at 350°C;
This method helps us relieve the internal stress of the metal, and protect ourselves from the appearance of cracks in the application, as well as increase its homogeneity.

You may be wondering what are the benefits of cast iron?

  • Durable product quality;
  • Reasonable and very affordable prices;
  • Wear resistance and strength;

Ultimately, industries that in the recent past have chosen steel over cast iron. Over time, however, they return to old and proven material.

Professional equipment helps to produce material in large volumes, without neglecting quality.
