SIDE ENTRY SUB

Offshore Operators are now specifying Integral Side Entry Subs manufactured from one piece of steel, but the problems are:  

Technical Specification:
› Very high material and machining cost.  
› When the WECO™ gets damaged the whole sub is written-off.  
› The integral one-piece design can result in hardness / strength variation in critical areas  
   
  The Sub-drill Flanged Side Entry Sub design is the answer:  
› The flanged side entry WECO™ can be replaced easily if damaged.  
› Avoids the welding and stress relief problems with 4145 H Mod steel of fabricated subs.  
› Reduced initial purchase cost compared to integral designs.  
› Special spigot design reduces strain on flange bolts.  
   
  When ordering, specify:
1 Rotary Connection types.
2 Lengths L / 2
3 WECO™ size and type
