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
Reducer pipe fittings are a type of pipeline component which reduces the diameter of the pipe from a larger to smaller bone. Comes in two different forms such as Seamless Reducer and Welded Reducer, we offer the international quality pipe reducers made up of steel and other alloys. The concentric type is easier and less expensive to produce, but does not allow quite the same. Nascent fittings exports and manufactures Buttweld reducer fittings in a variety of sizes, thickness and dimensions. It can be used as oil, gas, power plant, docks, water treatment plant, ship building chemical and petrochemical industries.
Typical applications
- Industrial piping and process systems using Buttweld Fittings
- Project supply of Buttweld Fittings for oil & gas, power, chemical and general industry
