Stainless steel pipe fittings have certain guiding significance for actual production.
Stainless steel pipe fittings
are widely used. With the rapid development of science and technology, stainless steel pipe fittings are widely used in aviation, electronics, chemistry, atomic energy and other industries, and the quality requirements for stainless steel pipe fittings are getting higher and higher. Based on the forming characteristics and finite element principle of LD type three-roll cold rolling mill, the large-scale nonlinear finite element simulation software MSC. Marc was used to simulate the three-roll cold rolling process of 302 stainless steel pipe fittings.
The research results of stainless steel pipe fittings have certain guiding significance for actual production. The effects of different process parameters such as feed rate, swing angle, friction coefficient and opening angle on the rolling results were analyzed. The influence of different feed rates and opening angles on the rolling force and the influence of the angle of rotation on the deformation induced movement of the pipe are discussed. Through the comprehensive analysis of the simulation results, reasonable process parameters are obtained, which provides a basis for parameter optimization. It can significantly improve the mechanical properties, dimensional accuracy and surface quality of stainless steel pipe fittings.
The calculation of stainless steel pipe fittings is most commonly calculated according to the seamless pipe. This means that the product is placed flat on the ground and viewed from above as the head of a pipe. The theoretical formula of the seamless pipe knows how to calculate it. It is possible to fit onto this large flange, which is the theoretical data of a carbon steel product (outer diameter - thickness) X thickness X0.02466.
The wear behavior and wear mechanism of stainless steel pipe fittings under seawater were measured by microhardness tester under different friction conditions, and the variation of hardness under seawater sliding conditions was analyzed.
Vifaa vya mabomba ya chuma cha pua vina umuhimu fulani wa kuongoza kwa uzalishaji halisi. Vifaa vya mabomba ya chuma cha pua hutumiwa sana. Pamoja na maendeleo ya haraka ya sayansi na teknolojia, fittings pikipiki chuma cha pikipiki ni sana kutumika katika anga, umeme, kemia, nishati ya atomu na viwanda vingine, na mahitaji ya ubora kwa fittings pikipiki chuma cha pikipiki ni kupata juu na juu. LD-Tip 3 Roll Cold Rolling Mill ni aina ya LD 3 Roll Cold Rolling Mill, ambayo ni aina ya LD 3 Roll Cold Rolling Mill. Kwa mfano, katika kesi ya mviringo wa baridi, mviringo wa baridi wa pua ya chuma cha pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua ya pua. Matokeo ya utafiti wa fittings pikipiki chuma cha pua na baadhi ya kuongoza umuhimu kwa ajili ya uzalishaji halisi. Athari za vigezo tofauti za mchakato kama vile kasi ya kulisha, pembe ya kugeuka, coefficient ya msuguano na pembe ya kufungua juu ya matokeo ya rolling zilichambuliwa. Ushawishi wa viwango tofauti vya kulisha na pembe za ufunguzi juu ya nguvu ya rolling na ushawishi wa pembe ya mzunguko juu ya mwendo wa deformation induced ya bomba ni kujadiliwa. Kupitia uchambuzi wa kina wa matokeo ya simulation, mantiki mchakato vigezo ni kupatikana, ambayo hutoa msingi kwa ajili ya parameter optimization. Inaweza kwa kiasi kikubwa kuboresha mali ya mitambo, usahihi wa vipimo na ubora wa uso wa fittings bomba chuma cha pua. Mahesabu ya fittings pikipiki ya chuma cha pua ni kawaida mahesabu kulingana na bomba seamless. Hii inamaanisha kwamba bidhaa ni kuwekwa gorofa juu ya ardhi na kutazamwa kutoka juu kama kichwa cha bomba. Theoretical formula ya seamless bomba anajua jinsi ya kuhesabu ni. Kwa mfano, kwa mfano, flange ya chuma ya kaboni, ambayo ina data ya kimantiki ya kipenyo cha nje na unene wa X 0.02466. Utendaji wa kuvaa na utaratibu wa kuvaa wa fittings za bomba la chuma cha pua chini ya maji ya bahari ulipimwa na mtihani wa microhardness chini ya hali tofauti za msuguano, na tofauti ya ugumu chini ya hali ya kuingizwa kwa maji ya bahari ilichambuliwa.
