Henan Laphan Industry CO.,Ltd:
1. Since 1988, Top 3 manufacturer of stainless steel bellows in China;
2. The Main Drafting Committee of National Standard for Bellows;
3. Qualified Supplier for Nuclear Power Plant;
4. ISO9001:2008 and ISO14001:2004 Certified.
1.Structure Parts:
Body, Sealing, short pige, Nut, Bolt.
2.Performance of metal metal flexible pipe coupling:
1) Flexible expansion joint provide adjustability to equipment installations by combining a Flanged Coupling Adapter
and a Flanged Spigot into one assembly.
2) Equipment connection applications include valve, pump, meter and other flanged fitting installations.
3) Longitudinal adjustment is provided by the telescoping action of the Spigot inside the Flanged Coupling Adapter.
4) When final installation position is achieved, the bolting procedure for the Flanged Coupling Adapter and the Flanged Spigot can be completed.
3.Applicable Scope of unclear industry metal flexible pipe coupling:
The metal product is functioned with pull and pres-sure resistance and excellent seal performance and easy installation. Hence it is widely used in power, metallurgy, drainage and sewage disposal to connect pump, vale and pipe, etc. It also has some multi-directional displacement during pipes operation so as to release blind plate propulsion and protect pipes, especially it makes it easy to install and maintain pipes. However, force- transferring joints shall be used on the pipe corner and pump exit, because, the joints can transfer blind plate propulsion from pump start to pump and pipe through force- transferring bolt and prevent pull to centralize close to pipe or pipe or damage equipment by impact force. Other joints can be selected freely for other positions. Our tenet: Your trust is our honor and we will manufacture high- quality products for you.
We can design and make the products according to your drawings and techincal requirements. The quality is better and the price is lower than the similar products another company make
4.Delivery time:
Within 30 days after receipt of the deposit
Packaging trem:
Unfumigation wooden case (Out package) and Plastic film and Textile membrane(inside package). We can make change as your request.
