Description

Series 65  – Jet Nozzle Assembly –  (316 Stainless Steel)

Our stainless-steel components have proven to improve durability, reducing damage caused by rust and corrosion to the body and nozzle retaining threads significantly reducing maintenance and costly tool repairs”. More importantly nozzle sizes can be quickly changed out in the field, without costly delays and/or down time,  allowing the operator to get back on bottom, focusing on production. 

The series 65 jet nozzle assembly comprises of a four part assembly, comprising of a weld on socket, tungsten carbide jet nozzle, threaded nozzle retaining jacket and O-ring. This assembly is ideal when building in-hole tools where high presser fluid is used to aid in the cutting (hole opening) by flushing the cutting surface, thus extending the life of the cutters and aiding in the cutting of  formations .

Properly placed jet nozzles are proven to increase the rate of penetration (ROP).  Increased ROP, reduces time and cost of the hole-opening operation thus reducing the overall operating cost.

High pressure flow, exiting the nozzles adjacent the cutting face, washes cuttings away from the cutting surface thus helping to increase the ROP, while improving the life of the cutters. Efficiently dislodging and moving the cuttings away from the leading edge of the cutter, insurers that cuttings are not being re-cut or act as an abrasives which will shorten the of fixed mechanical cutters.

The socket weldment can be ordered in two materials, C1045 Alloy Steel and 316 Stainless Steel.

Failsafe Nozzle Tool

A redesign of the Smith slotted extraction tool has virtually eliminated the problems associated with the design, i.e stripping of the tool and/or retainer slots.

Our retainer design uses a standard 1/2″ (S65) or 3/8″ (S45) socket/breaker bar for removing retainers and nozzles. This improved design eliminating the downtime resulting from damaged tools and/or nozzle slots.

It should be noted the thread-bore details are shown  “WITHOUT LEADING COUNTERSINK” & “WITH LEADING COUNTERSINK” leading face.  Where space permits, we recommend WITH LEADING COUNTERSINK as it helps protect the lead-in thread and Retainer face.

 

 

 

316 Stainless Material/Welding Notes

Physical Characteristics

“Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.” (Written by AZoM)

Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). Grade 316H, with its higher carbon content has application at elevated temperatures, as does stabilised grade 316Ti.


Corrosion Resistance

Excellent in a range of atmospheric environments and many corrosive media – generally more resistant than 304. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60 °C. Considered resistant to potable water with up to about 1000 mg/L chlorides at ambient temperatures, reducing to about 500 mg/L at 60 °C.

316 is usually regarded as the standard “marine grade stainless steel”, but it is not resistant to warm sea water. In many marine environments 316 does exhibit surface corrosion, usually visible as brown staining. This is particularly associated with crevices and rough surface finish. (Written by AZoM)


Welding 316 Stainless-Steel 

Excellent weldability by all standard fusion methods, both with and without filler metals. AS 1554.6 pre-qualifies welding of 316 with Grade 316 and 316L with Grade 316L rods or electrodes (or their high silicon equivalents). Heavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance. This is not required for 316L. Grade 316Ti may also be used as an alternative to 316 for heavy section welding.

Referenced below are links and excerpts from two widely recognized welding authorities for your quick reference. In addition to these, there are many others covering this topic throughout the internet as well as your local welding supply.

When in doubt, consult with a trusted welding distributor for advice on the process. Doing so can help ensure the durability — and the cost-savings — sought in an application featuring both stainless steel and carbon steel.

Tips for Successfully Welding Stainless Steel to Carbon Steel

“Welding differing materials, such as stainless steel and carbon steel, can be a more economical choice and it can improve durability of the completed components”.

“When welding stainless steel to carbon steel, it is critical to pay attention to chemistry, mechanical properties and corrosion resistance to avoid potential trouble. For all three factors, choosing the right filler metal can help reduce concerns.         

As an example, when joining 304L stainless steel to mild steel, the most commonly recommended filler metal is 309L. During the welding process, the weld becomes diluted with some of the stainless steel from one side of the joint and some of the mild steel from the other side, mixing in material from each side of the weld. The goal is to create a final weld deposit whose chemistry is compatible with each side of the weld joint.”
