塑料管道系统。玻璃纤维增强式热固性塑料元件。检验带有弹性密封件的刚性锁定管座套筒接头设计的试验方法。
Plastics piping systems. glass - reinforced thermosetting plastics components. test methods to prove the design of rigid locked socket - and - spigot joints with elastomeric seals.
初步设计工作应集中在关键元件上，这些关键元件的尺寸将影响其他元件的设计，例如有眼螺母和刚性支柱连接部件。
Initial design work should focus on components whose dimensions may affect the required designs for other components e. g. eye nuts and rigid strut connecting parts.
然后，通过回流焊接将安装元件固定到刚性板上，接着突出板被从安装元件上卸下。
Then, through reflow soldering, the installation element is fixed on the rigid board, and the protrusion board is detached from the installation element.
