A:
The coupling is manufactured using AISI 5140 alloy steel, which is highly resistant to hydrogen embrittlement.
Q:What surface treatment options are available?
A:
Customers can request phosphate chemical treatment or black oxide coating for the coupling surface.
Q:How does the thread rolling process improve strength?
A:
Thread rolling creates compressive stress at the root of the thread, strengthening the traditional weak point of cut-thread couplings.
Q:What is the warranty period for these products?
A:
The warranty period for all our products is 1 year, covering mechanical defects.
Q:What is the friction coefficient of the spray metal coating?
A:
