About
About Buttweld Fittings
Nascent fittings is a reputed manufacturer and exporter of a wide range of Buttweld fittings which are used in industrial pipe systems to change direction, branching and to mechanically connect equipments to the system including high temperature conditions like furnace.
Manufacturing note
Swage nipples are used to bring the flow of fluids from one pipe size to another pipe size. The function of a swage nipple is to change the pipe's diameter and to connect two pipes of different sizes. The swage nipple is divided into concentric swage nipple and eccentric swage nipple. Concentric swage nipple is mainly used for vertical pipelines; eccentric swage nipple is mainly used in horizontal pipelines. Nascent fittings produce swage nipples of customers with specific requirements. there are two types of swage nipples i.e. 1. Concentric swage nipples and 2. Eccentric swage nipple with numerous dimensions, sizes, materials and standards. The customers appreciate Swage nipples because they are manufactured with the highest quality components available and also for long service life, light weight, high strength and accurate dimensions.
Typical applications
- Industrial piping and process systems using Buttweld Fittings
