Based on DAAB documentation, the SqlHelper class also support transaction. What you have to do is create Connection and Transaction object manually and then passing it into you SqlHelper static method class.

For example :

using (SqlConnection cnn = new SqlConnection(ConnectionString))
{
    cnn.Open();
    SqlTransaction trans = cnn.BeginTransaction();

    try {

    // using ExecuteNonQuery with passing transaction object
    SqlHelper.ExecuteNonQuery(trans, "sp_YourSP1", [parameters collection]);
    SqlHelper.ExecuteNonQuery(trans, "sp_YourSP2", [parameters collection]);
    SqlHelper.ExecuteNonQuery(trans, "sp_YourSP3", [parameters collection]);

    trans.Commit();

    } catch (Exception ex) {

        trans.RollBack();

    }

}

CMIIW.
