## Casing Burst & Collapse Calc Description
Worried about casing failure downhole? Stop guessing burst and collapse ratings for every string design. Casing Burst & Collapse Calc gives you instant API 5CT pressure ratings so you can verify your casing program before running pipe.

Enter casing OD, weight, grade, and well data to get burst pressure (Barlow formula), collapse pressure with mode identification, tensile body yield, and biaxial stress checks — all with configurable safety factors.

BURST PRESSURE (INTERNAL):
- Barlow formula: Pb = 2 x Yield x t / OD
- Adjustable safety factor (default 1.25)
- Allowable burst rating for field decisions

COLLAPSE PRESSURE (EXTERNAL):
- Automatic collapse mode detection (yield, plastic, transition, elastic)
- D/t ratio calculation
- Safety-factored collapse allowable

TENSILE & BODY YIELD:
- Body yield strength in lbs
- Biaxial stress check per API TR 5C3
- Combined burst-tension envelope

WELL DATA INPUTS:
- True vertical depth (TVD)
- Mud weight (ppg)
- Formation pressure equivalent
- Safety factor override

CASING DATABASE:
- Sizes: 4.5", 5.5", 7", 9-5/8", 13-3/8"
- Grades: H-40 through Q-125
- Multiple weight options per size
- Auto-calculated wall thickness

Built for drilling engineers, casing designers, and wellsite supervisors. Works completely offline — no internet required.
