Types & Applications

Keyser offers a comprehensive range of flexible hoses. The main advantages of metal hose include high resistance to both high and low temperatures, high strength, high corrosion resistance. They also reduce significantly any vibration or noise. They connects rigid piping which are misaligned to moving parts of machinery and equipments. A variety of choice of metal is available. Eg. Bronze, stainless steel, monel and inconel.

		Corrugated Metal Hose Our complete range is widely used for conveying high pressure and temperature, corrosive and non-corrosive liquids, searching gases and dry materials. We are capable to manufacturing a full range from 1/4 to 16 ID. Available Materials Monel, Bronze, Carbon Steel, 321 SS, 316 SS
		Interlocking Hose Interlocked metal hose by helically winding and folding together the edges of specifically pre-formed metal strip. For low-pressure application or where pressure loss is to be held at a minimum, a pre-formed groove inside the interlocked joint is packed with copper/stainless steel wire and asbestos cord.
		Bellows Used primarily used as valve seals and pressure sensing devices, as well as flow channels for all types of media, Keyser Bellows are formed from lap-or butt-welded stainless steel, monel, inconel, hastelloy or any materials that can be weld. Available Materials Galvanized Steel, Stainless Steel, Bronze, Aluminum
		Interlocked Pressure Hose High grade treated non-metal packing is simultaneously wound with the metal strip and located in a formed groove. This non-metal high temperature packing in fully-locked construction withstands the pressures to conduct safely non-searching media like water, oils etc. Available in sizes from 1through 4 diameters.
		Tar & Asphalt Hose Used for handling dangerous hottar, asphalt and oil because of their great strength and dependability, Keyser Tar & Asphalt hose incorporates a special helical winding with an non-metal high temperature packing. These are available in a variety of sizes from 3/4 to 4 ID.
		Vibra Masters Keyser Vibra Masters are available in annular corrugated stainless/carbon steel or bronze hoses. Noises, together with pump vibration will be absorbed by these Vibra Masters. Available Materials Bronze, Steel, Stainless Steel

Types of Protections

A flexible metal casing is used to protect the annular corrugated metal hose when it is subjected to external abuse such as dragging etc. Flex-wound interlocked metal hose provides this additional protection. Other coatings such as synthetics are also available on request. There are 2 methods of protection.

Protection Cover
This basic construction type can be categorized by:
   a. Double overlap interlock type with packing
   b. Double overlap interlock type without packing
   c. Simple overlap squarelock type
   * Materials used are Monel, Bronze, PVC, Zinc & Stainless Steel

Double Braided

For very high pressure applications, double braided is recommended and for of moderate pressure applications, single braided is recommended. In low pressure applications, braiding is not necessary.

Types of Braid

		Ribbon Strip Braids These can be applied where cracks can be easily formed due to fatigue and high movement frequencies.    a. Exceed 3m in length    b. Used for stationary piping
		Flat Wire Braids    a. Used most frequently    b. Used primarily for moving pipes    c. Excels in flexible resistance and pressure resistance
		Braided Braids    a. Resistance to pressure significantly increases without sacrificing flex resistance    b. Increase in stretch ability    c. Maximum of 20 plys    d. Used primarily for moving pipes
