Customized Size Hydraulic Sealing Washers Spiral Wound Graphite Gasket

 

Metallic spiral wound gaskets are made of quality metal tapes and soft materials by winding them up spirally layer by layer alternatively, and the metal tapes are fixed at both ends by point welding. Metal tapes include steel Q235, stainless steel AISI304, AISI304L, AISI347, AISI321, AISI317L, AISI2205, AISI316L, AISI904L, titanium alloy and nickle alloy, and soft materials include graphite tapes, asbestos-free materials, PTFE, mica, etc.

 

Metallic spiral wound gaskets have the best elastic performance among semi-metallic sealing gaskets, and the structure density can be made according to different clamping forces, and maximum pressing force can be controlled by the internal and external steel rings, the contacting flange surfaces do not have high-degree of accuracy.

 

Metallic spiral wound gaskets are especially suitable for situations where loads are not well distributed, combining forces are easy to lose, temperature and pressure have periodical changes and impacts and vibration exist.

 

Metallic spiral wound gaskets are the idealistic static sealing parts for the flange connecting places of pipes, pressure vessels, condensers, valves, pumps, heat exchange facilities, towers, manholes.

 

Scope of applications:

Petroleum, chemical industry, metallurgy, electric power, ships, machinery, medical and medicine industry, nuclear energy as well as aerospace industry.

 

 

Basic Type(type A)

There are no soft materials included within the last several circles of metal tapes near the inside and outside of the gaskets in order to keep the pressure force and sealing performance of the part.

 

Internal Strengthening Type(type B)

The solid internal ring plays a role of strengthening the performance of the gasket, the internal ring lies between the flange inner hole and the main ID of the gasket, the purpose of designing the inner ring is to prevent the accumulation of solid matters on the flange surface, to reduce the leakage of fluids as well as to reduce the corrosion of the fluids to the flange. Suitable for male and female face flanges.

 

External Strengthening Type(type C)

The external ring is designed to fix the gasket precisely on the surface of the flange and at the same time functions to prevent the collapse of the gasket when under pressure. Suitable for plain flanges and male flanges under pressure of less than 2500Mpa.

 

Internal and External Strengthening Type(type D)

To add an internal ring to the external strengthening makes the Internal and external strengthening type gasket, the internal ring functions to prevent the collapse and deformation when under pressure. Suitable for plain flanges and male flanges under pressure of more than 900Mpa or with corrosive fluids.

Quality Control:
We have strict auditing before determining to choose a supplier. The auditing covers machines, test facilities, records, management as well as supplier's management staff's attitudes towards our concept of business and our requirements.

The suppliers are required to keep records of and put labels to each incoming production materials and each production procedures to ensure that the products and quality are controllable and traceable according to ISO9001 system. We will carry out inspection of semi-finished products and finished products, not including the supplier's own internal daily in-process inspection, to guarantee that the quality of the goods will match and exceed customers' expectations.

And more importantly, each supplier will be carefully chosen before production because we have to ensure there will be no potential risks in production.

For parts to be used in automobile industry, we supplier full set level 3 PPAP documents and carry out SPC analysis to ensure the parts can reach customers' requirements.

Packing of Goods:
The goods are packed in neutral 20-25kg outer cartons, or in small boxes first then in 20-25kg cartons on fumigated wooden European-type or American-type pallets. And if customers have special requirements on cartons or small boxes with special prints, it will also be feasible for us.Moreover, we can also supply the goods in various kinds of plastic small boxes according to respective customer requirements.

 

Payment Terms:

30% wire transfer after order confirmation and the balance should be paid against copy of bill of lading after delivery, or we can do L/C at customer’s requirements.

 

Delivery Terms:

FOB, CIF or DDU according to customer’s requirements.

Shipment:
The agreed timetable of delivery of goods will be strictly followed. And in case of urgent need, we may also make special arrangement for customers. We may make shipments with full containers, less load containers or airfreight for customers.


Shipment documents:

We will supply commercial invoice, packing list, bill of lading, certificate of origin, insurance policy and certificate of inspection within 3-5 days after delivery.
