Single Bellows Expansion Joints

Accord custom manufactures single bellows expansion joints in 1-1/2" through 96" diameters. Bellows design follows EJMA (Expansion Joint Manufacturers Association) standards and all welding is in accordance with ASME Section IX. T-321 stainless steel is the most widely used material for bellows applications. Accord can also fabricate expansion joints in other alloys such as Inconel 625, Inconel 600, Inconel 825, Monel 400, Hastelloy C276, T-316-L stainless steel, T-304 stainless steel, T-310 stainless steel and many other alloys.

Non-standard and metric sizes can also be furnished by Accord.

Plate Flange Single Bellow: Economical plate flanges are drilled to ANSI B16.5 specifications with machined flat face finish. Raised faces are optional. Standard material is A-36 carbon steel with stainless steel and other alloys available. Accord has complete machining capabilities to meet your custom flange requirements.

Forged Flange Single Bellow: Forged flanges may be required to meet codes or elevated pressure requirements.  A105 forged steel and A184 stainless raised face slip on flanges are available in 150#, 300#, 600#, and higher classes with many different flange facings.

Vanstone Flanged  Single Bellows: Accord manufactures vanstone stub ends in a variety of materials and thickness.  Stainless steel, Inconel, and Monel stubs can be used with carbon steel back up flanges. The flow media only contacts the bellows and stub ends.

Forged Lap Joint Flanged Single Bellows: High-pressure applications may not be able to use vanstone stub ends. Lap joint stub ends can also be furnished in many different alloys and pipe schedules.

Plate Flanges With Tie Rods: Accord utilizes a triangular design on standard tie rod flanges. When (4) rods are required for pressure considerations, a square flange design is used. Standard flange drillings are to ANSI B16.5 specifications. Custom flanges are always available to meet customer requirements.

Beveled Weld End Single Bellows: Standard wall A53 carbon steel pipe is cut to any length and beveled for welding. Other pipe such as A106 GR B seamless, T-304 stainless steel, T-316 stainless steel and other exotic alloys can be furnished in all available pipe schedules.

Flanged Bellows with Pipe Spacers: With the use of pipe extensions, expansion joints can be made to required overall lengths.  These joints can reduce the cost of additional modifications in the field. Pipe spacers also provide an area for optional flow liners to travel.

Exhaust Bellows Expansion Joints

Expansion joints provide the ultimate vibration isolation and flexibility at the engine exhaust manifold.  System expansion joints are required to absorb the thermal expansion of the piping.  The sales and engineering departments at Accord are eager to assist in selecting the proper expansion joints for your system.

Fixed Flanged  Exhaust Bellows: Flanges are welded rigid on both sides. 1/2" thick plate flanges are most common for exhaust and blower applications. Stainless and carbon steel flanges can be fabricated with any bolt pattern in any size.

Vanstone Flange Exhaust Bellows: Floating flanges or vanstone flanges eliminate bolt alignment problems.  Accord fabricates vanstone stub ends in stainless and other alloy materials. Carbon steel back up flanges are an economic solution.

Multi-ply Flanged Bellows: By design these joints have very low spring rates. On engine manifold applications, multi-ply expansion joints can absorb and isolate vibration and at the same time absorb certain amounts of thermal expansion.  For critical applications such as marine and co-generation, multi-ply joints are a must.

Flanges with Spacer Tube: The bellows length is generally limited to 12" in length. When a longer assembly is required, fabricated stainless steel tubes are used.  For standby applications, carbon steel tubes are available.

Flanged with Spacers and Liner: Flange spacers are furnished in T-321 stainless steel. Expansion Joints can economically be furnished in any length. When a flow liner is required, spacer tubes prevent contact damage to the bellows.

Polly Pig - Pipe Line Cleaners

Accord polly-pigs are constructed of open cell polyurethane foam of various densities and is available with various types of external coatings. Although each pig has a specific application, some pigs are interchangeable according to the user's preference within certain parameters.

Polly-Pigs are molded of polyurethane foam material of light, medium, or heavy density. Its bullet shape is designed to aid in traversing fittings and valves. Concave ends are available for bi-directional service. The length of the pig are approximately twice its diameter to reduce the possibility of the pig tumbling in the pipeline. The diameter of the Polly-Pig is larger than the inside diameter of the pipe. This is done to exert a frictional drag between the foam pig and pipe wall. Pigs can be ordered to any custom size requirements.

Polly-Pigs have a concave base plate with a 90A durometer polyurethane coating. This provides a maximum rear sealing surface for the propelling forces of the fluids or gases being used.

Swabs or bare pigs, which have only the bases coated, are normally used in drying or batching operations. Special double-nose or double-dished pigs are used in bi-directional service. The exterior coating on the foam bodies consists of criss-cross type spirals of 90A durometer polyurethane. These spirals add strength and give greater wiping and scraping action as compared with bare foam.

Notes: Density: Scarlet = 8 lbs. / cu. ft.; Density of Red = 5 lbs. / cu. ft.; Density of Yello

Reflex Gage Glass, Conbraco Water Gage, Sight Glass, Washers, Glass Cutter, Polycarbonate Tubing

Reflex Gage Glass: Are specifically designed to make reading liquids easier. Reflex gage glass have prisms in the face, as the liquid flows across the glass it reflects giving a clear view of the level. Accord also supplies the gaskets and mica to make a complete replacement kit.

Conbraco Water Gages: These water gages are equipped with ball checks to prevent scalding the operator in the event of glass breakage. The sudden rush of steam and water will carry the balls to their seats thereby shutting off the escape of steam and water. 1/4" Needle Drain Valve in lower arm standard - 1/4" Pet cock in lower arm available upon request. Note: Conbraco water gages do not include glass tubing or brass guard rods. Accord International can supply both items. Glass tubing can be cut to your specifications.

Circular Sight Glass: Are used to allow observation within a sealed vessel or hazardous area. Applications include port holes, pressure vessels, chemical tanks, etc.. Circular sight glass is available in both toughened and annealed forms. Please provide Accord technical sales with the maximum temperature and pressure the glass will be exposed to and we will be pleased to offer solutions.

Gage Glass Washer: These gaskets are made from a heat resistant compound that is flexible enough to allow proper expansion of the molded lip against the glass. Correctly installed, with lip toward the bottom of the stuffing box, the applied pressure will force the lip tightly against the glass forming an effective seal and at the same time cushioning the glass from the metal. The outer wall will simultaneously expand against the stuffing box nut preventing pressure escape from the outside. The washer section is made thin enough to allow the glass to become adjusted to its proper alignment without any danger of breaking. When installing gaskets the nut should be made up thumb and finger tight. A wrench should not be used.

Gage Glass Cutter: This gage glass cutter has a chain that is wrapped around the glass tube and scores the glass allowing for nice clean cuts. The gage glass cutter can be used to cut any length from 1/2" to several feet long. This is the most popular glass tubing cutter.

Polycarbonate Tubing: Properties of polycarbonate tubing are much lighter than the weight of comparable glass, better shatter resistance and has excellent durability. Polycarbonate tubing will not warp, crack, corrode, resist aging and maintains good stability under heat, cold, moisture and other exposure.
