SAFE CONNECT A comprehensive and reliable local waste water collection and removal solution to protect human health and the environment and support existing infrastructure. This is a very important criteria for any waste water collection and removal system. Another important criteria is that the waste water network‘s pipe joints must remain hermetic throughout the system’s operational life, without causing additional local stresses on the surrounding environment at pointtype pollution sites.

We obtain CANDAS system connections which during the operational life of the pipes prevent infiltration of underground water (groundwater), and prevents seepage of polluted waste water into the soil, thus preventing local point-type soil pollution. The assembly of the pipe components at the construction site is a simple matter of lubricating the end of the pipe with the rubber sealing ring then inserting the pipe extension, using basic tools. A tight fit for the pipes is achieved thanks to profiled EPDM rubber sealing rings, which guarantee the hermetic sealing of the connection points (pressure 0.5 bar).

EPDM raber sealing which optimises interaction between the extension and the rubber sealing ring, further improving the positive characteristics of the flexible pipe system.

Complies with EN 13476-3+A1 and INSTA SBC EN 13476

QUALITY OF THE DWC PIPES The voluntary compliance with the institute and the acquisition of the quality certification involves: • PROCESS CONTROL through monitoring, recording and checking process and product parameters (temperature, pressures, extrusion speed, processing anomalies) • PRODUCT CONTROL, all the tests made according to EN 13476-1 are carried out on the product at a steady cadence. These tests are the minimum requirements that must be withstood and maintained by the product. The tests results are summarized in a “test report” that is at the customer’s disposal and it certifies the tests that have been carried out successfully.

• PERIODICAL CONTROL AUDITS: CANDAS carries out, through its network os inspectors, control visits and sample tests on the finished product and on the operating documents.

As a complete guarantee of this, the manufacturer has implemented a Company Quality Management System, in keeping with the UNI EN ISO 9001:2000 norm.

An element of quality of the CANDAS product is the ability to fully comply with the strict specifications defined by the relevant norm EN 13476-1.

This quality must be guaranteed to the client and maintained steadily in all the phases of the production process in order to assure use suitability and resistance throughout the life of the products.

For this reason the manufacturer has decided to refer to a third body for what concerns the guarantee of the CANDAS product quality by means of conformity to the EN 13476-1.

REFERENCE NORMS: EN 13476-1 GUIDELINE FOR INSTALLATION & USE TRANSPORT •

Suitable vehicles shall be used, with at platforms and no sharp edges which may damage the pipes.

•

Carefully load the pipes and secure them by suitable load restraints to the truck.

•

Load by alternating the pipes so that the sockets of the pipes don’t squash during transport.

•

In the loading lay-out, put the bigger sizes at the bottom and the smaller sizes at the top of the load.

FIG.1 Check the conformity of the goods

RECEPTION While unloading always check the conformity of the goods to the purchase speci cations and/or the reference norms, in particular: •

check indications given by marking;

•

check macro defects of geometry or any other visible defect (e.g. abrasion, surface conditions);

•

check the integrity of the joining components.

Particular of the sealing gasket joint system and marking

FIG.2 Transport in pallets Transport of spare pipes with ropes

UNLOADING& HANDLING •

Use suitable devices for unloading and handling the pipes.

•

Avoid fork damage, injuries, abrasions, rough handling and any other damage. The safety of the operator shall be ensured any case.

•

While unloading do not make use of hooks at the ends of the pipes.

•

Use ropes or strops instead.

Stocking gaskets and ttings

STORING •

Store the pipes by laying them on a at surface, with wood gluts put at a suitable distance, without sharp edges, stable, protected and sheltered.

•

The height of the stack will be according to the size of the pipes.

•

Stack the pipes alternating the pipes, in order to put the socket in one side and the plain end in the opposite side.

•

Store ttings and sealing gaskets in special places protected by sun rays, heat, oil and grease.

•

Do not install gaskets during storage.
