For the purpose of heating the internally supported end section of the pipe, the end section is first heated until the end section has reached, substantially homogeneously, the glass transition temperature of polyvinyl chloride and is then further heated until the end section has reached, substantially homogeneously, a temperature near, preferably just above, the orientation temperature of polyvinyl chloride.

Process for forming laminated pipe

A laminated tubular structure is obtained by a process in which a fabric sleeve is applied about a tube of thermoplastic polymer, following which plugs are inserted into the opposing ends of the liner. A liquid, such as water, is then introduced to the liner, and the liner is rotated about a horizontal axis while heat is applied to the exterior surface of the liner, causing the surface to become molten. The heat also causes vaporization of some of the liquid in the liner and the resulting vapor pressure causes the molten surface of the liner to expand radially into the interstices of the fabric sleeve. The inner surface of the liner remains solid and form-maintaining by reason of the liquid within the liner and heat absorbed on vaporization of liquid. Upon cooling there is obtained a good mechanical bond between the liner and sleeve. The liner-sleeve composite can be further reinforced by a surrounding layer of a thermosetting resin containing reinforcing fibers, the resin layer being bonded ...

Method and device for heating preform

While blowing out cooling air to a preform which is biaxially stretched and blow molded into a bottle shape, heat sources are made operative by a high power and the first heating process as quick heating is performed to the preform. Subsequently, the heated preform is left as it is and a temperature adjusting process to reduce a temperature difference between an outer surface temperature and an inner surface temperature of the preform to a predetermined value or less is executed. The second heating process to heat the preform until the outer surface temperature is equal to a temperature which is slightly lower than a crystallization temperature of the PET is executed to the preform obtained after completion of the temperature adjusting process while blowing out the cooling air to the preform. Thus, the quick heating of the preform is safely accomplished without causing an overheating state.
