Method for use of stainless steel elbow

Written by

The main alloying element in stainless steel is a Cr (Cr), only when the Cr content reaches a certain value, the steel corrosion resistance. The corrosion resistance of stainless steel decreases with the increase of carbon content, and therefore, most of the stainless steel and carbon content are low, the largest of no more than 1.2%, some steel wC (carbon content) and even lower than 0.03% (such as 00 cr12).
Stainless steel is generally at least 10.5% Cr (chromium) content. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, si and other elements.
The stainless steel elbow in accordance with the method of accurate and reasonable use.
A, stainless steel elbow of ball valve, cut-off valve, gate valve, when using only for full open or full close, do not allow for regulating flow, lest sealing surface erosion, accelerated wear and tear. Gate and thread on the globe valve with pour sealing device, the handwheel back to the top position and tighten, to prevent leakage of media from the packing.
Second, the long-term storage of stainless steel elbow, should be timely check, often appear the processing surface should be clean, remove dirt, neatly stored in a dry indoor drafty place, it is strictly prohibited stacking or in open air. Often kept stainless steel elbow dry and drafty, keep clean and tidy, deposit deposit according to the accurate method.
Third, when installation, stainless steel elbow can be device directly based on the mode of connection in the way of tube, carried out in accordance with the use of the location of the installation. In general, can be installed on the pipeline at any position, but need to test for easy manipulation, should pay attention to the flow direction of medium by the stainless steel elbow is high, the longitudinal disc below stainless steel elbow can only be installed horizontally.
Stainless steel elbow should pay attention to when installing sealing to prevent leakage phenomenon, on the affect the normal operation of the pipeline. Precipitation hardening stainless steel common brands such as 04 cr13ni8mo2al. It can pass the precipitation hardening (also known as the age hardening) dealing with the hard (strong) of stainless steel.
