51 steel pipe network analysis of buried insulation pipe knowledge and polyurethane foam insulation performance

51 steel pipe network provides: Directly buried insulation pipe, also known as the "tube in the tube," which consists of "two steps", is composed of high density polyethylene outer protective layer, polyurethane rigid foam insulation material and steel pipe. The insulation material is a rigid polyurethane foam with a density of 60kg/m3 to 80kg/m3, which fully fills the gap between the steel pipe and the casing, and has a certain adhesive strength, so that the steel pipe, the outer casing and the heat insulation layer are among the three Form a solid whole. Polyurethane directly buried insulation pipe foam has good mechanical properties and thermal insulation properties, usually under high temperature resistance of 120°C. It can withstand high temperature 180°C through modification or combination with other insulation materials. It is suitable for all kinds of cold and hot water high and low temperature pipelines. Thermal insulation works. For more information on directly burying insulation pipes, please pay attention to our steel pipe knowledge channel: http://?id=3

Small Rotary evaporator 1l 2l 3l 5l for essential oil cbd hemp oil distillation and extraction


Rotary evaporator 1liter-- RE201D

Rotary evaporator 2liter-- RE201E

Rotary evaporator 3liter--RE301

Rotary evaproator 5liter--RE501 with ptfe bottom discharge valve


The purpose of the rotary evaporator rotovap is to remove low boiling organic chemicals, usually solvents, from a mixture of compounds .


The rotary evaporator always for distillation and extraction under vacuum pressure . The motor runs the rotation flask moving and heating water oil bath pass hot energy to the mixture of rotary flask . Then low boiling point of mixture will be heated and form a thin film and make evaporation . The lower boiling point mixture make morphological change from liquid to Vapor or hot air . Then hot vapor meet condenser cooling coil then become liquid again and fall down to collection flask .
