Inner String Cementing 
Utilizing the proven stab-in system for placement, Innovex’s inner string cementing products are well-suited for large diameter casing and offshore well cementing.
By pumping through the drill pipe or tubing, operators can reduce circulation time and pump rates while eliminating the need for drilling out a large volume of cement from the casing.
306 Stab-In Float Shoe
The 306 Series utilizes Innovex’s proven HFX phenolic plunger valve, and is typically fitted with a round nose that helps guide the casing to the target depth. It can also be provided with ports (up, down and side) and various types of noses to suit different applications.
341 Stab-In Float Collar
Complete with the high temperature, high strength phenolic HFX valve, the 341 Series Stab-In Collar features a balanced spring force that ensures sealing occurs even in low differential pressures.
316 Stab-in Float Shoe
The 316 Stab-In Float Shoe is fitted in the HFX plunger valve and robust stab-in receptacle for optimum inner-string cementing. Like the 306 Series, this float shoe can be provided with ports (up, down and side) and various types of noses to suit different applications.
351 Stab-In Float Collar
Like the 341 Float Collar, the 351 Series is ideal for large diameter casing, where cement can be pumped through drill pipe or tubing, reducing cement displacement time and volume pumped.
