Ductile iron fittings

The properties of ductile iron are due to spheroidal shape that particles of graphite that eliminate the spread of possible ruptures lines. This is achieved thanks to a stage of the production process in which magnesium vapour injection causes the nodulation of graphite. All our tubes and accessories are made with regard to the rules IN 545:2007 and ISO 2531:1998. Tuberia Moreno has them certified and approvals that guarantee his fitness for design, manufacture and market parts cast of casting ductile according to them criteria of quality of the normative current.

Coating

Types of coating inside and outside:

ECB: Epoxy e-coat blue 70 μm

PECB: Powdered blue reinforced epoxy 250 μm

VEC: Epoxy Cataphoresis black 35 μm

VBi: 70 μm bituminous varnish

pressure maximum manageable

Them pipes of "Tuberia Moreno" are designed to withstand pressures high, in general very upper to them values common of operation of them networks. Pipes must be to support the numerous solicitations to which they are subjected during its construction and with the passage of time. For this reason the maximum pressures are established safety coefficients that take into account, not only efforts due to internal pressure, but also other solicitations, sometimes accidental.

The resistance to the pressure of an accessory depends of:

· The resistance of the body

· The type of used Board

Thrust force

Thrust forces are calculated:

F = K / S P F = thrust (N)

P = pressure inside maximum or pressure of test in work (Pa)

S = cross-section - interior for flanged joints; outdoors for all remaining types (m2)

K = coefficient, function of the geometry of the accessory used.

types of flanges

Flange gasket is made up of two opposing flanges, elastomer gasket washer and screws, whose number and dimensions depend on DN and PN. It sealing is achieved by compression axial of the washer obtained by the tighten of them screws,therefore, the tightness is function directly:-of the pair of tighten of them screws and -of the design of the washer of together (with or without soul metal). Its main features are: · Precision of Assembly · Possibility of mounting and dismounting online (repair, visit, maintenance) for DN < 600, the brackets are adjustable.
