The main factors that cause the cracking of the cylinder tube

What are the main factors that cause the cylinder tube to crack?There are the following points:

1. Raw material selection:In order to save costs, some oil cylinder pipe manufacturers will choose round steel produced by small steel mills for processing, but the round steel produced by these small steel mills will have a large number of air bubbles and gas holes after post-processing, which is easy to cause cracking.Procurement from manufacturers, certificate of reliable supply.

2. Insufficient heat treatment temperature control:Small manufacturers do not have professional production experience and technology.Workers in the workshop cannot guarantee whether the heat treatment of the steel pipe is in place only by the heating temperature and duration. Heat treatment will affect the change of the mechanical properties of the steel pipe. Meet customer requirements performance indicators.
