The past month of November published the Spanish version of the new norm JOINS-IN 545:2011 “Tubes, racores and accessories of ductile smelting and his unions for channelling of water. Requirements and methods of essay”. It treats of the Spanish transposition of the European norm IN 545 approved to finals of the year 2010, which answered to the demand of the European Committee of Normalisation (CEN) to review regularly the different European norms. The aim of the review of the normative is to ensure the good adecuación of the norms to the needs of the users and integrate the innovations and the technical evolutions that allow a greater efficiency and optimisation of the consumption of the natural resources.

The main change in the new version of the norm JOINS IN 545:2011 it corresponds to the criterion of denomination and dimensioning of the pipes of ductile smelting, happening of a classification by thicknesses to a classification by classes of pressesure. Like this it creates a clearer system of classification of tubes, with a direct correspondence between the nominal diameter and the pressesure of operation.

Of this form, obtain the following classification: C20, C25, C30, C40, C50, C64 and C100; according to the functional approach that recommends CEN for the components of a network. This classification also coincides with the international rule of reference for the pipes in ductile smelting ISO 2531, and that considers the recommendations of the norm JOINS IN 14801:2007 'Classification of pipes of water in function of the pressesure', which conjuga the provision of pressesure with the different combinations regarding conditions of installation.

Classes of pressesure

The norm JOINS IN 545:2011 it allows to the user determine of way very clear the maximum levels and minima of pressesure in which a pipe of ductile smelting can use in function of the real needs keeping the coefficients of traditional hygiene of this type drivings.

The class of pressesure defines the PFA (Pressesure of Admissible Operation) of the component. C40 offers a provision of 40 bar regarding the pressesure that the component can resist of permanent form in service; remaining defined also the different notions of resistance to pressesure of the component:

- PMA: Admissible Maximum Pressesure, that integrates the on pressesures PMA = 1,2 x PFA

- PEA: Pressesure of Admissible Essay, maximum pressesure of proof for the reception of the installations PEA = PMA + 5 bar.

The PFA this determinate with a high coefficient of hygiene of three regarding the break. The mechanical resistance of the tubes of the classes of preferential pressesure allows a high provision to level of the installation, regarding the heights of maximum and minimum coverages, fulfilling with the cases more desfavorables that can give in the usual installations. For those cases in which the preferential classes do not satisfy the needs of the users, the norm allows the election of classes of upper pressesure for a wide range of diameters of pipes.

Pipes range 'PAM Irrigal'

In base to the new version of the norm JOINS IN 545:2011, that replaces and cancels totally the previous version of 2007, the range of pipes for irrigation ‘PAM Irrigal' that Saint-Gobain PAM Spain offers to his customers fulfils the specifications of the new version of this norm.

Of this way, the class C40 corresponds to diameters DN 150-300 mm and the class C30 to DN 350-600 mm.

With the norm JOINS IN 545:2011, Saint Gobain PAM replaces totally the pipes of previous irrigation.

Saint-Gobain PAM Spain has of the certification of compliance with the norm IN 545: 2010, established by a certifier organism for all the points of production and different ranges.

Advantages of the range ‘PAM Irrigal'

The contribution of the necessary dose of water to the crops by means of the irrigation demands hydraulics infrastructures that transport the water from his origin until the point of growth of the crop. The execution of these infrastructures supposes a strong economic investment, by what his provision have to be reliable and durable. Thus, the main advantages that offers the range ‘PAM Irrigal' of Saint-Gobain PAM Spain are: guarantee of estanqueidad; hygiene; ease of setting and installation; durability; adaptation to greater provision in the future; resistance to heavy traffic; compliance with the Spanish norm, European and international ISO; economy; experience of more than one hundred years in Spain and reciclabilidad.

To complement the range of irrigations, Saint-Gobain PAM Spain offers pipes DN 700-1000 Class C30 and an extensive range of accessories.

The new version of the norm JOINS IN545:2011 it collects significant changes with regard to the compatibility of the tubes and installed accessories. It does big upsetting in the importance of the hygiene and compatibility of the unions and, besides, demands a minimum thickness of 70µm in the revestimiento of the accessories.

Second phase of the project of irrigation located in the CCRR Virgin of the Snows of Aspe (Alicante).

From finals of the past year all the accessories of Saint-Gobain PAM Spain are revestidos according to norm. His offer happened of 35 to 70 µm in the range of accessories of big diameter, offering his innovative revestimiento by electrodeposición from DN 80 to 1200 mm. The accessories of Saint-Gobain PAM Spain, have a revestimiento only in the market. The application of painting epoxy by means of cataforesis offers a coating of the internal and external surface homogéneo; highly resistant to the corrosion; maximum adherencia of the painting to the matrix of ductile smelting and, thanks to the polymerisation of the resin, a big mechanical resistance and chemical in front of possible aggressions that the piece can suffer in the transfer, manipulation and/or installation. That is to say, a revestimiento for all his useful life.

The range 'PAM Irrigal' allows to combine tubes and accessories by means of different unions very was mechanical or automatic board.

Boards acerrojadas STD Saw (arrive) and Sees (down).

The union tube-tube, bell-smooth realises with the known Standard automatic board bilabial, that allows a maximum angular deviation, that guarantees the estanqueidad without need to realise any tighten external. The range of accessories of Standard mechanical union would realise by means of the same Standard board, what supposes a saving of costs or specific needs covers thanks to unions acerrojadas like the Standard Saw, Standard Sees, Universal Saw and Universal Sees available for the market of irrigation.

In what to the unions of pipe and accessories refers , Saint-Gobain PAM Spain engages with the current needs of the installations, offering unions pre-instalables thanks to the mechanical board Expresses and settings-desmontajes without hardly effort, with angular deviation, the maximum of the market of the channelling of ductile smelting.

Saint-Gobain PAM Spain has updated the triptych of the range 'PAM Irrigal' with the end to offer all the information to the relative user to the new normative and the changes produced in the range 'Irrigal'.
