Abstract
Использование: сборочное производст- во, нефт на промышленность, металлурги . Сущность изобретени : изготавливают трубу, замок в виде ниппел и муфты, соедин ют ниппель и муфту замка с трубой, изготавливают уплотнитель из меди или ее сплавов, деформируют его путем раздачи в радиальном направлении при температуре, равной 0,2-0,65 температуры плавлени материала уплотнител , и напр жении, равном 2-12 кг/мм2, охлаждают в воде, разгружают, соедин ют уплотнитель с резьбой ниппел и нагревают его до температуры , при которой осуществл ют деформирование.Usage: assembly production, oil for industry, metallurgists. The inventive pipe is made, the lock is in the form of nipples and couplings, the nipple and lock clutch are connected to the pipe, the sealant is made of copper or its alloys, it is deformed by radial distribution at a temperature of 0.2-0.65 melting points sealant material and a voltage of 2-12 kg / mm2 are cooled in water, unloaded, the sealant is connected to the nipple thread and heated to a temperature at which deformation is carried out.
Description
Изобретение относитс к области термомеханической обработки металлов и может найти применение в металлургии и нефт ной промышленности.The invention relates to the field of thermomechanical processing of metals and may find application in metallurgy and the oil industry.
Цель изобретени - повышение надежности трубы.The purpose of the invention is to increase the reliability of the pipe.
Изобретение отличаетс тем, что перед соединением уплотнител с резьбой ниппел осуществл ют деформирование уплотнител путем раздачи в радиальном направлений при температуре, равной 0,2- 0,65 температуры плавлени материала уплотнител , и напр жении, равном 2-12 кг/мм4, с последующим охлаждением в воде и разгрузкой, а после соединени уплотнител с резьбой ниппел его нагревают до температуры, при которой осуществл ют деформирование.The invention is characterized in that before connecting the seal with a threaded nipple, the seal is deformed by distributing in the radial direction at a temperature equal to 0.2-0.65 melting point of the seal material and a voltage of 2-12 kg / mm4, followed by by cooling in water and unloading, and after connecting the seal to the threaded nipple, it is heated to the temperature at which deformation is carried out.
П рим е р. Брали трубу В-114х9-Д ГОСТ 631-75 с ниппелем и муфтой замка ЗШ-178 по ГОСТ 631-75. Изготавливали взрывным штампованием под замковую резьбу 3-147 замка ЗШ-178 уплотнитель в виде тонкой (толщиной 0,1 мм) коническойR eme r. They took a pipe V-114x9-D GOST 631-75 with a nipple and a clutch lock ZSh-178 in accordance with GOST 631-75. Made by explosive stamping under the locking thread 3-147 of the ZSh-178 lock, a sealant in the form of a thin (0.1 mm thick) conical
оболочки с выдавленной резьбой из меди, которую после штамповани отжигали. Проводили Деформирование уплотнител путем раздачи в радиальном направлении в услови х ползучести при и напр жении 7,5 кг/мм с последующим охлаждением в воду. После наворзчиванй и зат жки уплотнител на ниппель уплотнитель вновь нагревали до 350°С, вызыва обратную ползучесть.shells with extruded copper thread, which were annealed after stamping. The sealant was deformed by distributing in the radial direction under creep conditions at a stress of 7.5 kg / mm, followed by cooling into water. After tightening and tightening the seal onto the nipple, the seal was again heated to 350 ° C, causing reverse creep.
