ກະດານແມ່ນຫຍໍ້ເປັນແປນເຊິ່ງເປັນພຽງ ຄຳ ສັບທົ່ວໄປ. ມັນມັກຈະ ໝາຍ ຄວາມວ່າມີການແກ້ໄຂຫລາຍໆຮູທີ່ຖືກສ້າງຂື້ນຮອບບໍລິເວນໂລຫະຄ້າຍຄືແຜ່ນ ສຳ ລັບເຊື່ອມຕໍ່ສິ່ງອື່ນໆ. ສິ່ງນີ້ໄດ້ຖືກ ນຳ ໃຊ້ຢ່າງກວ້າງຂວາງທາງກົນຈັກ, ສະນັ້ນມັນເບິ່ງຄືວ່າແປກ, ຕາບໃດທີ່ມັນຖືກເອີ້ນວ່າ aແປນ, ຊື່ຂອງມັນແມ່ນມາຈາກພາສາອັງກິດ.
ກະດານ is also called ແປນ or ແປນ. The parts connecting the pipe and the pipe are connected to the pipe end. There are holes in the ແປນ, and the bolts tightly connect the two ແປນs. The ແປນs are sealed with gaskets. ກະດານ is a disc-shaped part, the most common in pipeline engineering, ແປນs are used in pairs. In pipeline engineering, ແປນs are mainly used for connection of pipelines. At the end of the two pipes that need to be connected, install a ແປນ each. Low-pressure pipes can use wire ແປນs, and welding ແປນs for pressures above 4 kg. Add a gasket between the two ແປນs, and then tighten with bolts.
ຄວາມກົດດັນທີ່ແຕກຕ່າງກັນ ແປນs ມີຄວາມ ໜາ ແຕກຕ່າງກັນແລະໃຊ້ໄລປະຕູຕ່າງໆ.
ໃນເວລາທີ່ປັwaterມນ້ ຳ ແລະວາວເຊື່ອມຕໍ່ກັບທໍ່, ບາງສ່ວນຂອງອຸປະກອນເຫລົ່ານີ້ກໍ່ຖືກຜະລິດເຂົ້າກັນແປນ shapes, also called ແປນ connection.
Any connecting parts that are bolted on both sides and closed at the same time are generally called "ແປນs". For example, the connection of ventilation pipes, this type of parts can be called "ແປນ parts".
ກະທູ້ແປນ is a kind of ແປນ. The connection structure of the threaded ແປນ is a combination, which is composed of a pair of ແປນs, a number of bolts, nuts and a gasket.
