About the Curva, M/F

A curva M/F é a mesma curva de raio longo, exceto que uma das pontas tem rosca macho (externa) e a outra rosca fêmea (interna) — exatamente a diferença entre um cotovelo macho e fêmea e um cotovelo comum.

Essa combinação reúne duas vantagens: a passagem suave do escoamento que a curva proporciona e a possibilidade de rosquear diretamente numa válvula ou num equipamento com bocal fêmea, sem niple intermediário. Menos perda de carga e uma junta a menos na linha.

Na sucção e no recalque de bombas, onde o espaço é apertado e o escoamento é rápido, é uma escolha comum.

A ponta macho veda na rosca, de modo que a precisão da usinagem importa. A curva M/F TUPY é fornecida como figura 1; ferro fundido maleável, rosca BSP conforme EN 10242, galvanizada ou preta.

Frequently asked questions about the Curva, M/F

In which sizes is the TUPY Brazil Curva, M/F made?

The TUPY Brazil Curva, M/F is made in 11 sizes, from 1/4" to 4". The full list of sizes, with the dimensions in millimetres and the weight of each piece, is in the dimensions and weights table on this page.

How much does one TUPY Curva, M/F weigh?

The weight depends on the size: the 1" size, for example, weighs 0.364 kg galvanised and 0.349 kg black. The weights of every size are taken from the official TUPY catalogue and are listed in the table on this page, so they can be used to work out shipping weight and freight cost.

Is the thread on the TUPY Curva, M/F BSP or NPT?

TUPYBSP fittings are threaded to BSP in accordance with ISO 7-1; the male thread is tapered and the seal is made on the thread itself. BSP is not interchangeable with NPT, and screwing the two together will leak. TUPY also produces a separate NPT line, which is covered in the downloads section.

What is the difference between a bend and an elbow in TUPY fittings?

An elbow has a short radius and turns the line within a short distance. A bend has a longer radius, causes less pressure loss and suits high-velocity flow or lines that scale up. The figure 1 bend is male at one end and female at the other, the figure 2 short bend is female at both ends and the figure 3 long bend is male at both ends.

What is the maximum working pressure and temperature of TUPY fittings?

According to TUPY's technical catalogue, the working pressure of TUPYBSP fittings is 25 bar between −20 °C and +120 °C. It falls to 20 bar above 300 °C, and intermediate values are interpolated. The design pressure in the hydrostatic test is 100 bar for sizes up to 4 in and 64 bar for 5 in and 6 in.

To which standards is the TUPY Curva, M/F manufactured?

The TUPY Curva, M/F is manufactured to EN 10242 / ISO 49. TUPY malleable cast iron fittings are built to ISO 49, EN 10242 and ABNT NBR 6943, and their threads follow ISO 7-1. The factory certificates can be seen in the standards and certifications section on this page.

How can you tell a genuine TUPY Brazil Curva, M/F?

On the body of every genuine TUPY fitting the factory mark, the figure number and the size are raised in the casting, not etched or printed. The threads are clean and free of burrs, and the galvanised coating is even. The surest check is to weigh the piece and compare it with the weight table on this page; counterfeit pieces usually come out lighter than the official catalogue weight.
