The welcome visits Shandong Hairui Zhonglian Pump Industry Co. , ltd. Website, the conduit pump that my company is a major produces manufacturer. When you need conduit pump type selecting, we will provide the before-sales service such as price of pump of conduit pump model, conduit, in order to offer your referenced alternative. This product information is the knowledge that reachs pipe fitting requirement to stainless steel flange about pump of stainless steel conduit:
Pump of stainless steel conduit uses the pump that stainless steel material makes character, commonly used have 304 commonly, 316, 316L, stainless steelConduit pumpHave certain corrosion resistance can, the flange when using stainless steel pump and conduit also are had normally be able to bear or endure corrupt sex, stainless steel flange is commonly used link unit, because of medium caustic, what do flange and pipe fitting have to cankerous influence?
Stainless steel pipe fitting and flange produce a business, want to consider pipe fitting produces cost, but should consider the factor that prevents to corrode and improve product quality more, accordingly, flange of stainless steel pipe fitting produces a process to adopt solid dissolve technology, enhancing pipe fitting security is very necessary, heat treatment craft is having crucial effect to pipe fitting character and safety. As we have learned a few enterprise is managing cost in pipe fitting production, did not take solution treatment, use polishing spray only arenaceous wait for methodological processing, masked the blemish of pipe fitting and inadequacy, this will be used to pipe fitting bring permanent hidden trouble.
Austenite stainless steel connects overheat to handle bate, heat stainless steel to 950 ～ 1150 ℃ are controlled, heat preservation is certain time, make carbide dissolves equably with all sorts of alloying element in austenite, those who say for solution treatment.
The element of dissolve of solid of stainless steel pipe fitting: The actor bad of craft of dissolve of solid of stainless steel pipe fitting is right of stainless steel be able to bear or endure brilliance of corrode sex, surface has very big effect, and the treatment function to stainless steel, having conclusive effect. Accordingly, the heat treatment craft of stainless steel, very significant position is in in production of stainless steel pipe fitting.
1, solid dissolve time. Austenite stainless steel is heating in the process, leftover ferrite content is followed in steel heat the extension of time and decrease. Accordingly, pipe fitting solution treatment should control stainless steel to be controlled in 1050 ℃ , make carbon achieves saturated status, rise be able to bear or endure corrode sex. Cool quickly in air after that, in order to achieve solid dissolve result.
2, solid dissolve temperature. According to the characteristic of composition of stainless steel chemistry, temperature of dissolve of stainless steel solid wants 950-1150 Celsius, ability achieves bate result, make stainless steel hardness reductive to 220HV less than, achieve conduit to install card to control quality demand. If temperature control is unreasonable, appear easily all sorts of quality blemish.
3, solid dissolve speed and heat preservation. The coefficient of thermal conductivity of stainless steel is inferior, 27% what be carbolic steel only in the coefficient of thermal conductivity when normal temperature, accordingly, stainless steel is in the process warms up to answer when microtherm heats slow undertake. If heat rate is too rapid, easy generation is out of shape, stainless steel should be controlled to warm up in solid dissolve speed, note heat preservation time. If 316L steel is controlled in 1100 ℃ , heat preservation time is long, the content of leftover ferrite can decrease ceaselessly.
Credit must choose when choosing pump of stainless steel conduit and flange of stainless steel pipe fitting so reliable, the high grade manufacturer that quality assures, also can raise conduit pump the assurance of service life.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is aboutPump of stainless steel conduitTo stainless steel flange and the introduction that pipe fitting asks, still think to this problem like you deep one pace understanding, or the problem that has price of model of type selecting of product of other pump industry, water pump, water pump, water pump needs to solve, contact this water pump manufacturer please, my company returns production to suck pump oneself, welcome you at any time seek advice.
