Simulating group_concat MySQL function in MS SQL Server 2005?

I have two table namely ServiceEntryPart and Part. One service entry could have multiple parts. What I am trying to do is to concatenate different parts for the same service entry. The final entry I am looking for is to have something like below”

 ServiceEntryID     PartDescription
       3            2 ~ xyz Manager | 3 ~ Elevator

In the Column Part Description, different part ids are concatenated in one column by using part id first followed by a tilda and part description followed by a Pipe character and the same format for different parts in the serviceentry part. Any help would be appriciated. thanks

please find the structure below

dbo.ServiceEntryPart
ID   ServiceEntryID   PartID
266  2                1
234  3                2
234  3                3
233  5                4

dbo.Part
ID  PartDescription   
1   Sample Manager
2   xyz Manager
3   Elevator

SELECT ServiceEntryID, PartDescription = 
    STUFF((SELECT ' | ' + CAST(b.ID AS NVARCHAR) + ' ~ ' + PartDescription
           FROM Part b
            INNER JOIN ServiceEntryPart c
                ON c.PartId = b.ID
           WHERE c.ServiceEntryID = a.ServiceEntryID
           FOR XML PATH('')), 1, 3, '')
FROM ServiceEntryPart a
GROUP BY ServiceEntryID
