يُستخدم الكبلن المخفّض لوصل ماسورتين مختلفتي القطر. وكلتا الفتحتين بسن أنثى، لكنهما ليستا بالمقاس نفسه.
وتغيّر القطر في الخط ليس مسألة أبعاد فحسب؛ فهو يغيّر أيضاً سرعة السريان. والانتقال من قطر كبير إلى صغير يرفع السرعة، وقد يسبب على خطوط البخار أو المياه عالية الضغط ضجيجاً وتآكلاً. ولذلك يهم الشكل الداخلي للانتقال ونعومة سطحه.
يُورَّد الكبلن المخفّض من توپي بالشكل رقم 240، وهو مصبوب من الحديد المطاوع وأسنانه في الطرفين مُشغَّلة على مواصفة BSP استناداً إلى EN 10242.
ويتوفر بمجموعة من توليفات المقاسات، مجلفناً وأسود.
The TUPY Brazil كبلن مخفّض is made in 26 sizes, from 3/8"×1/4" to 4"×3". 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.
The weight depends on the size: the 1.1/2"×1.1/4" size, for example, weighs 0.260 kg galvanised and 0.253 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.
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.
The figure 270 socket is female at both ends and joins two pipes of the same diameter; its reducing version is figure 240. The figure 280 nipple is male at both ends and joins two female parts; its reducing version is figure 245. The figure 241 reducer is male at one end and female at the other and screws inside a socket or a tee to bring the diameter down. The figure 529A M/F extension piece is longer and acts as a connector; its reducing version is figure 246.
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.
The TUPY كبلن مخفّض 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.
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.
