A support frame for pipe cutting comprises a frame body and rolling devices mounted on the frame body, wherein the frame body comprises two pieces of parallel angle steel (1) and two mutually parallel steel bars or steel pipes (2); the corner edges of the angle steel (1) face up; the steel bars or steel pipes (2) are horizontally welded between the corner edges of the two pieces of angle steel; the rolling devices are two rolling bearings or pulleys (3); and the two steel bars or steep pipes (2) are sleeved with the rolling bearings or pulleys (3) respectively. During pipe cutting operation, two support frames provided by the invention are adopted, workers only need to carry or lift a to-be-cut pipe manually and then place the two ends of the to-be-cut pipe on the rolling devices of the support frames respectively, and then the to-be-cut pipe can be rolled easily by one person. Therefore, time and labor are saved and safety and high efficiency are ensured.
