Specification of material and cross-sectional data of tees (Input Table)

Data description/conditions:

TEE-REF:

Reference name of tee connection

Required / Must be unique and correspond with TEE-REF defined in table TEECONF

TYPE:

Type of tee

Required / Prescribed names: Welded, Reinforced, Unreinforced, Extruded, Welded-In, Welded-On

(For definition of tee types see NEN-EN 13480-3 APPENDIX H. Available are: welded tee, reinforced fabricated tee with pad or saddle, unreinforced fabricated tee, extruded welding tee, welded-in contour insert tee and branch welded-on fitting tee.) (2)

MATREF:

Material reference of tee

Must occur in lists specified in tables ISTROP and / or ANTROP, may be left blank

(If Undefined (empty), the material is taken as specified in table MATL.)

MATBRN:

Material reference for branch of tee

Must occur in lists specified in tables ISTROP and / or ANTROP, may be left blank

(If Undefined (empty), the material is taken as specified in MATREF. If this in turn is also blank, the material is taken from table MATL.)

D-RUN:

Outside diameter of run

> 0. / Undefined (1)

(If Undefined (empty), the diameter is taken from table DIAM.)

T-RUN:

Wall thickness of run

> 0. / Undefined (1)

(If Undefined (empty), the wall thickness is taken from table WALL.)

(If value entered, the wall thickness corrosion allowance and the wall thickness tolerance (relative or absolute) are taken from table WALL.)

D-BRN:

Outside diameter of branch

> 0. / ≤ D-RUN / Undefined (1)

(If Undefined (empty), the diameter is taken from table DIAM.)

T-BRN:

Wall thickness of branch

> 0. / Undefined (1)

(If Undefined (empty), the wall thickness is taken from table WALL.)

(If value entered, the wall thickness corrosion allowance and the wall thickness tolerance (relative or absolute) are taken from table WALL.)

TE:

Thickness of pad or saddle

> 0. in case of Reinforced type, otherwise blank

R0

Radius of curvature of external contoured portion of outlet

> 0. in case of Welded, Extruded or Welded-In type, otherwise blank

CON:

State of transition of the weld for Reinforced, Unreinforced and Welded-On tees

Prescribed name Smoothed (smooth concave contour) or blank (not smooth)
