Product Detail1

Shanghai Metal Corporation is a leading Bourdon tube manufacturer and supplier.

The elastic deformation of the Bourdon tube converts the elastic deformation of the Bourdon tube into a rotary motion via a conversion mechanism of the movement inside the watch, causing the pointer to deflect to display the pressure.

Our company has LG30, LG20, LD15 multiple cold Rolling mill production line, 6T, 3T, 1T multiple cold drawing machine production line, Bourdon tube automation, semi-automatic production line. It is equipped with a complete set of production equipment such as straightening machine, bright annealing and ultrasonic.

Q1.What is the MOQ and production lead time?

A:MOQ is 3000 pcs per specification; production lead time is typically 15~20 working days after order confirmation

Q2.What information do you need for a custom quotation?

A:Material grade, drawing and quantity

Q3.How long does sample preparation

A:Samples are prepared within about 20 working days after the specification is confirmed

Q4. How do I choose the right Bourdon tube material for my medium?

A:For non-corrosive media (air, water, oil) choose CuSn bronze tubes; for corrosive media in chemical and process industries choose 304/316/316L stainless steel; for strongly corrosive media (seawater, concentrated alkalis, hydrofluoric acid) choose Monel 400.

Q5. What range and dial size should I select?

A:Select a range so that normal working pressure stays within about 75% of full scale under steady load, protecting accuracy and tube life; choose Y40–Y70 for compact OEM or confined spaces, Y100/Y150 for panel mounting or reading at distance.
