Purchase Order of Gaskets from Russia

Cooperation Process

This customer is one of the stable customers for our company. We have been keeping in touch with each other since fist cooperation for nearly a near. Until now, We still get continuous inquiries from the customer.

As for this order, the sales just received a mail at first with description and amount. Because of the lack of technical details ,we assumed Li 10 was the gasket used for flanges, but the thickness of it didn't meet the standard requirement. So the sales sent mails to communicate with the customer but didn't get effective reply. We didn't arrange the producing because  there must be something misunderstood, so we continued to mailed them and noticed them the timeline.

At last , we got pictures for reference from our customer and supplied the right product to them.

What is Gasket ?

Gaskets are mechanical seals between two objects, usually used to prevent pressure, corrosion, and natural thermal expansion, contraction, and leakage of the pipeline between two objects. Since machined surfaces cannot be perfect, the use of shims can fill in irregularities.

Classification of Gaskets

• Non-metallic gasket: Gaskets made of asbestos, rubber, synthetic rubber, polytetrafluoroethylene and other non-metallic gaskets. A Non-metallic coated gasket Non-metallic jacket gasket with synthetic resin, etc.

• Semi-metallic gasket: Gaskets made of metal and non-metallic materials, such as spiral gaskets, metal-covered gaskets. Spiral wound gasket is a spiral wound gasket consisting of a V-shaped or W-shaped section of metal strip with non-metallic strips, spirally wound. The inner ring is set on the metal ring of the inner ring of the winding gasket. The outer ring is set on the metal ring of the winding gasket.

• Metal gasket: It is a gasket made of steel, aluminium, copper, nickel or Monel alloy.

• Winding gasket: It refer to gaskets that are toroidal with metal strips (usually V-shaped steel strips) and non-metal strips. Metal strips and non-metal strips are alternately wound. Because of their good elasticity, they are widely used in flange sealing structures in petrochemical, chemical, power and other industries. According to specific parts, steel rings can be added to the inner or outer layers of gaskets to locate or strengthen them.
