Nut metal hose usually refers to a type of metal hose that uses nuts as a connection method. Its common model parameters mainly include the following aspects:
1、 Basic dimensional parameters

1.  Nominal Diameter (DN) :
-Common nominal diameters include DN6, DN8, DN10, DN15, DN20, DN25, DN32, DN40, etc., up to larger diameters such as DN100, DN150, etc.
-The nominal diameter refers to the inner diameter or flow diameter of a hose
2.  Hose length :
-The length range usually ranges from 0.5m to 4m, with common lengths including 0.5m, 1m, 1.5m, 2m, 2.5m, 3m, 3.5m, 4m, etc.
-The length of the hose can be customized according to actual needs to accommodate different installation spaces and pipeline layouts.
3.  Wall thickness of hose :
-The range of wall thickness is usually between 0.15mm and 4.0mm, with common wall thicknesses including 0.15mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm, etc., up to thicker wall thicknesses.
-The wall thickness affects the pressure bearing capacity and service life of the hose, and thick walled hoses are suitable for high-pressure environments.
2、 Pressure and temperature parameters
1.  Work pressure :
-Common working pressures include 2.5KG pressure, 6KG pressure, 10KG pressure, 16KG pressure, 25KG pressure, etc. There are also working pressures expressed in MPa, such as 0.6MPa to 40MPa.

-The selection of work pressure should be determined based on the actual needs of the pipeline system to ensure the operation of the hoses.
2.  Working temperature :
-The common working temperature range is -196 ℃ to+450 ℃ (or -235 ℃ to 600 ℃), depending on the material and design of the hose.
-When selecting hoses, factors such as the operating temperature of the pipeline system and the thermal expansion coefficient of the medium should be considered.
3、 Connection method parameters
-The nut connection method includes connecting one or both ends with a nut and a joint, such as connecting one end with a ball head sleeve nut and one end with an inner cone joint, and connecting the two ends with ball head sleeve nuts.
-Nut connections have the advantages of simple structure, convenient installation, easy disassembly and maintenance.
4、 Material and Performance Parameters
1.  Pipe body material :
-Common pipe materials include stainless steel (such as 304, 316, 316L, etc.), carbon steel, etc.
-The selection of materials should be based on the medium
