PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is performed.

FIELD OF INVENTION:
This invention relates to the steam traps used on the pipeline in the process industries or where steam is required to be carried through pipes. More particularly it discloses about a universal mounting arrangement in one product.
BACKGROUND OF INVENTION:
The steam traps are used on the pipeline in the process industries or where steam is required to be carried through pipes up to user location. During travel of steam through pipes it is likely to get condense. This condensate presence in the pipeline is not recommended. This need to be removed as and when it is formed. For this automatic removal of condensate process and not to allow live steam to escape, this product is used.
In the existing conventional flange mounting arrangement, the flanges have to be in stock for 2 sizes ratings i.e. Sizes 15/20 NB and rating as #150 & #300. Hence one has to keep 4 components in stock. Further to this, these flanges do require in different international standard compliances like weld neck raised face (WNRF), socket weld raised face(SWRF), slip on raised face (SORF) Hence it will lead for 4X3 = 12 variances. As against the same, integral flange arrangement will eliminate above and manufacturer can accommodate either of these basic 4 sizes and ratings as per customers requirement.
Further, the existing art work calls for welding activity. This calls for approval of welder and process. In addition to above extra manpower is required. All above activity is laborious and lead to large manufacturing cycle time for job completion. In existing art, few customer demand for pipe and flange with butt weld joint. To perform the same, high skill sets of welders are required as this process calls for radiography inspection for compliance of joint correctness and is mandatory with most of the regulations. This further adds to cost of mfg.
In existing method, pipe is required, which will be eliminated in proposed invention to minimize no. of assembly components, inventory and cost too. In the existing method due to welding process feasibility overall length will be @ 160.0 mm.

In present process of manufacturing steam traps welding activity is involved. Various components like Pipes & flanges are required. Working fatigue is high. Being small in size welding is tedious which adds to fatigues & stress to the workmen. The manufacturing process needs additional non destructive tests hence addition in cost. In the conventional method there are chances of leakages at joints as joints are likely prone to the leakage as welding is joining process. The overall dimensions of the conventional steam traps are more.
Existing art ask need based mounting arrangement products on pipe line i.e. for four different mounting arrangement we need to have four different products in stock.
The attached cross sectional drawing is for the product called as steam traps. These are used on pipelines in the process industries which carries steam as a media. This media is likely to get condense during its travel & formation of condensate in steam pipeline is not recommended. This condensate need to remove from the pipeline as & when it is formed. For this above said product is used.
To mount this product, variety of arrangements are available in pipeline engineering as per the international standards. One of them is flanged end connection. These flanged ends are rated with different pressure ratings based on pipeline pressures. The most commonly flange ends widely preferred by customers is class 150 & class 300. There are various types of steam traps viz. Thermodynamic steam traps, Thermostatic steam traps, Bimetallic Thermostatic steam traps, etc.
Referring to Figure 1 the body of the conventional Thermodynamic steam trap along with top cover and Filter cap forms a steam trap. This steam trap if it is to be fitted on the pipeline in the process industries or where steam is required to be carried through pipes up to user location through flanged connections, then said steam trap has to be welded with components like seamless pipes & flanges. Moreover after manufacturing the said product needs additional non destructive tests hence addition in cost as there are chances of leakages at joints as the joints are welded and they are likely prone to the leakages.

Referring to Figure 2 the body of the thermostatic steam trap along with top cover and filter cap forms a steam trap. This is having bellows which expands when steam enters and contracts when condensate comes. These expand when temp, is high (i.e. when steam enters the trap ) & contracts (i.e. when condensate enters in the trap). After expansion the bellow seats on the valve seat making trap to close and does not allow steam to pass. This steam trap if it is to be fitted on the pipeline in the process industries or where steam is required to be carried through pipes up to user location then said steam trap has to be welded with components like seamless pipes & flanges. Moreover after manufacturing the said product needs additional non destructive tests hence addition in cost as there are chances of leakages at joints as the joints are welded and they are likely prone to the leakages.
Referring to Figure 3 the body of the Bi-metallic thermostatic steam trap along with top cover and strainer cap forms a steam trap. This is having Bi metallic controller plates which are sensitive to temperature. These Bi metallic controller plates expand when temp. is high (i.e. when steam enters the trap ) & contracts (i.e. when condensate enters in the . trap). These are provided with stem guide & nut for its positioning with respect to seat. This steam trap if it is to be fitted on the pipeline in the process industries or where steam is required to be carried through pipes up to user location then said steam trap has to be welded with components like seamless pipes & flanges. Moreover after manufacturing the said product needs additional non destructive tests hence addition in cost as there are chances of leakages at joints as the joints are welded and they are likely prone to the leakages.
We will have to develop a steam traps which normally has no welding involved in manufacturing and will eliminate all above drawbacks.

The bimetallic controller plates senses high & low temp, of media & accordingly expands & contract respectively.
The Integral one piece flanged type bimetallic steam trap is manufactured from a solid bar by drilling and machining operations. The valve seat (45) provided is either integral with the body (41) or is a separate piece. The steam trap is abstained from any additional non destructive tests being a one piece assembly. The Integral one piece flanged type Bimetallic steam trap is compact within a range of 80 to 140 mm length leading for compact assembly.

Advantages of Invention:
• Integral single piece assembly
• No fatigue on the assembly being single piece assembly
• No welding activity involved hence no non-destructive tests are required
• Full proof mechanism as no chance of leakage being one piece assembly
• Universal mounting arrangement in one product.
Universal mounting arrangement ensures one product suitability for four different mounting arrangements. Four combinations can be taken from one basic part size during machining. For example four holes at four different Pitch circle diameters (PCD's) can be accommodated in the same steam trap during manufacturing so that pipes of different sizes and different pressure rating can be incorporated without maintaining specific inventory for flanges of various sizes. As per the general principle for low pressure pipe lines the PCD of the mounting holes can be of smaller diameter and as the pressure increases the PCD of mounting holes goes on increasing. This variation can be easily accommodated in the body of the present steam trap design. This also helps in eliminating the dependency of the vendors supplying the said flanges thereby reducing the product delivery time.
In second embodiment (referring to figures 8, 12, 15) the aforesaid steam traps are also provided with threading (15, 35, 65) at the inlet openings (9, 33, 63) and at the outlet opening (10, 34, 64) respectively such that the same can be matched with the threaded portions of the pipes of the pipeline for assembling said steam traps in required location on the pipeline.
In third embodiment (referring to figures 9, 13, 16) the aforesaid steam traps are also provided with plain openings (16, 38, 68) at the inlet opening (9, 36, 66) and at the outlet opening (10, 37, 67) such that the same can be matched with the non-threaded pipe portions of the pipes of the pipeline for assembling said steam traps in the required location on the pipeline by welding.
