Foreword
This standard is one bite type pipe fittings series.
The standard tube fitting structure type and dimensions ISO 8434-1.2007 "Metallic tube connections for fluid power and general use
Part 1. 24 ° compression fittings "(in English) of the relevant part of the basic agreement.
This standard is GB/T 3737.1-1983 "card sets straight couplings" and GB/T 3737.2-1983 "card sets through connector
Amendment Style ". The main amendments are as follows.
--- The two standard content integration;
--- Modify the English name;
--- The nominal pressure G (250) and J (400) to modify the maximum working pressure of 10MPa ~ 63MPa, and is divided into LL, L and S three
Series; series of product size range of adjustment has been made;
--- Adjust the size of the pipe diameter range, and revised the relevant size;
--- Reducing the parameters should be part of the manufacturer's control;
--- Cancel the weight data;
--- Cancel the marked surface roughness, surface roughness is given in GB/T 3765 "bite type pipe joint technical conditions" in.
