Overview list of specified characteristics of joints in pipeline based on element list (Output Table)

Data description/Result options:

ELEM:

Element number assigned to joint

JOINTREF:

Reference name from input tables PIPES and JOINTS or JNTSPRS

TYPE:

Type of joint

(Socket-L:        socket-spigot connection without stop
Socket-S:        socket-spigot connection with stop
Spigot-L:        spigot-socket connection without stop
Spigot-S:        spigot-socket connection with stop
Sleeve-L:        double socketed coupling sleeve without stop
Sleeve-S:        double socketed coupling sleeve with stop
Ball:                ball hinge (free rotations in all directions)
Hinge:                pin hinge (free rotation around one axis)
Tight:                connection with resistance to tensile strain, no free translations and rotations
Bellows:                bellows type of connection with axial, transverse, rotational and torsional stiffnesses)

x-C:

Clearance in axial socket direction in case of compression ¹

x-T:

Clearance in axial socket direction in case of tension ¹

MaxRot:

Maximum possible free lateral rotation ²

Rotdir:

Angle between the plane of rotation and the horizontal plane ³

IniRot:

Initial lateral angular difference in the joint

THETA:

Initial angle between plane of the elements adjacent to the joint and the horizontal plane

OVALtype:

Indication of ring stiffness of joint construction to be used for redistribution of element ovalisations in function 6.1

[Default: a FREE end condition]

k-AX:

Axial stiffness of joint

k-LAT:

Lateral (transverse) stiffness of joint

k-TORS:

Torsional stiffness of joint

k-ROT:

Rotational stiffness of joint

 


¹ Undefined for TYPE = Ball, Hinge or Tight


² Undefined for TYPE = Tight only


³ (≥ 0. AND < 360.) if TYPE = Hinge, else Undefined

 

Info The stiffnesses remain constant during the calculations in Design Function 5.
