48.3*5.1 Pipe Elbow Fittings ASTM 403 WP304L 45° 90° 180°

PIPE ELBOW FITTINGS 90° 48.3*5.1 Silver white ASTM 403 WP304L .45° and90° 180°are the most commonly used

In a pipeline system ,an elbow is a pipe fitting that changes the direction of the pipeline. According to the angle ,there are 45° and 90° 180° three most commonly used,in addition,according to the engineering needs ,there are other abnormal angle bends such as 60'.Thematerials of the elbow are cast iron ,stainless steel,alloy steel,malleable cast iron,carbon steel,non-ferrous metals and plastics.

The ways to connect with the pipe are:direct weiding(the most commonly used way)flange connection ,hot melt connection ,electric fusion connection ,ephemeris connection and socket connection ,and so on.Other names:90degree elbow,right angle bend,etc

becase most of the pipe fittings are used for welding, in order to improve the welding quality, the end of the car is formed into a groove, leaving a certain angle side ,thie reqirement is also relatively strict .The thickness of the edge ,the amount of angle and the range of deviation specify that the surfacec quality and mechanical properties are basically the same as those of the pipe .For the sake of welding convenience ,the steel between the pipe fittings and the pipe to be connected is the same as that of the pipe to which the pipe is connected .The species are the same

That is ,all the pipe fittings should be treated bu surface taeatment ,the iron oxide coating on the inner and outer surface should be sprayed out by shot peening treatment ,and then coated with anticorrosive paint .This is what the exit needs ,and then in orded to facilitate transportation to prevent corrosion and oxidation ,,all of them hane to do this work in China .

The requirement for packaging is that for small pipe fittings ,such as export, it is necessary to make wooden cases ,about1 cubic meter ,prescribing that the number of elbows in such boxes shall not exceed one tonne.This standard allows for suits ,that is ,large sets and small sets ,but the total weight shall generally not exceed 1 ton. For the big Y ,you have to package it ,like the 24",you have to package it ,and it's the packing label. Remeber, the mark is to indicate the size ,steel number ,bath number, manufacturer's trademark and so on.
