Why does clotting of blood not take place in uninjured blood vessels?

Blood clotting does occur for blood in uninjured blood vessels due to its insulation from air. Our bodies produce what is called heparin that prevents clotting of blood in vessels. Heparin allows our lungs to transfer oxygen to our blood. When blood is exposed to air it clots so heparin allows the blood to come in direct contact with the air we breath without clotting.

How many minutes will take to blood clot after death?

Blood clotting begins shortly after death due to the cessation of circulation, with the process typically starting within minutes. However, the complete clotting process can take several hours to fully develop, depending on various factors such as temperature and the individual's health prior to death. Generally, noticeable clots can form within 20 to 60 minutes post-mortem, but significant changes in the blood's state may continue for hours.
