The NB 530/900 manhole is made of rotationally molded polyethylene and is intended for embedding in concrete blocks for various types of district heating chambers, both for new installations and for repairs of older leaky chamber roofs.

The descent well is supplied with an EPDM rubber embedding ring (W802). The embedding ring is mounted with a hose clamp and can be adjusted on site to suit different embedding heights.

The manhole cover, made of rotationally molded polyethylene, is rubber ring sealed and insulated with polyurethane cellular plastic, which provides a waterproof and heat-insulating manhole cover.

Frequently asked questions about sealings

How much load can the sealings generally withstand?

It is important to note that the sealings are not intended to act as supports. The pipes must be supported on both sides of the seal.

Which sealings can withstand axial movements?

W801, W803 and W804 are all tested for generous axial movements.

Do your sealings protect against both radon and water?

Many of our sealings protect against both radon and water. You can see from the labels on the products which ones protect against what.

Where can I find more data sheets for other products?

How big sealings can you deliver?

We have sealings in stock with a diameter of up to 1000 mm. We have the ability to build custom sealings and have supplied sealings up to 2000 mm diameter, but there are no limits to how large sealings we can make.

Call or email us to discuss your sealings needs in more detail. 033-10 04 40 or info@skelda.se

Does W802 work on corrugated pipes?

It is possible to install W802 on corrugated pipes provided that it lies on one or more of the tops of the pipe. Should there be very wide gaps on large pipes, it may be necessary to seal the gap in the corrugation before installing the seal.

Do you have any radon sealing that is Nordic Swan Ecolabeled?

W802 is included in the House Product Portal and is therefore approved for Nordic Swan Ecolabel projects. These types of sealings cannot be Nordic Swan Ecolabeled and this also applies to competitors' products. But if they are included in the House Product Portal, it works.

Which sealings are approved for radon?

W801, W802, Link Seal, Compact and Nofirno are all approved radon sealings.
