START ProfTHE WORLD’S FIRST PIPE STRESS ANALYSIS SOFTWARE

PSRENTP Truboprovod


START Advantages compared to other pipe stress software Low price. Two times lower than other pipe stress software

Has a long history since 1969 Has a lot of active users, well tested, quality assurance system Very smart, easy and friendly user interface. Even the beginner can perform pipe stress analysis without a special training. Faster piping modeling than other software Exclusive software that implements the Russian pipe stress code and widely accepted by Russian expert companies Very smart, fast and easy to use soil modeler Can check the insulation stress No need to think about load cases. All load cases are pre-defined Can calculate the creep effect at high temperature piping: creep stress relaxation in operating state and creep self-springing in cold state Can calculate the cold state of piping after cooling down from hot state considering the reverse effect of friction forces


START Advantages compared to other pipe stress software Can easily perform plastic piping analysis PE (polyethylene), PP

(polypropylene), PVC (polyvinyl chloride), PB (polybutylene), PVDF (polyvinylidene fluoride) Can easily perform FRP/GRP/GRE piping analysis Easy vacuum piping stability analysis from pressure, and internal forces Automatic on-the-fly pressure design checking of all pipes and fittings

Soil Database contain soil properties, depth, soil type and insulation type is specified in pipe properties. That’s all you need to model buried piping with START


No need to select restrained and unrestrained zones for buried piping. Everything calculated automatically

No need to run soil modeler each time you change your model. Soil springs are placed automatically during analysis. Very fast


START also consider the buoyancy of water and changing of the soil properties located in water (soil liquefaction)

START consider the remaining friction forces at the cold condition of the pipeline. No analog in other software. It is important for pre-

stretched buried pipelines

Operation condition of above ground pipeline

Cold condition of above ground pipeline (after cool down). There’s a big anchor force due to remaining friction
