Product Description
Alloy 718 Introduction.
Alloy 718/2.4668 is a nickel-chromium iron alloy with niobium and molybdenum and low contained aluminum and tnum. Excellent mechanical properties in lower temperatures. Excellent corrosion resistance at high and low temperatures
Inconel 718 is a nickel based super alloy that is well suited for applications requiring high strength in temperature ranges from cryogenic up to 1400°F. Inconel 718 also exhibits excellent tensile and impact strength.

Threaded Latrolet/Elbolet Introduction
1.Product Definition:
Threaded Latrolet and Threaded Elbolet are forged integral branch reinforcement fittings manufactured to MSS SP-97 standard. Threaded Latrolet is welded on straight pipe for 45° angled threaded branch connection. Threaded Elbolet is mounted on 90° elbow to create threaded outlet. The branch end is machined with standard NPT thread for threaded pipe connection.
2.Structural Features:
One-piece forged construction delivers dense metallurgical structure. The curved saddle base fits tightly against the outer
surface of host pipe or elbow. Internal NPT threads are precisely machined, ensuring tight sealing. No extra reinforcing plate is required, which avoids weak points from patch welding.
3.Applicable Working Conditions:
They are widely used in petroleum, chemical, power and natural gas piping systems for medium and high pressure service. Available materials include carbon steel, stainless steel, alloy steel and Inconel 718. Common pressure classes are 3000LB and 6000LB, ideal for sampling, venting and instrument tapping points.
4.Installation Method:
The saddle base is welded onto the outer wall of the main pipe or elbow by continuous fillet weld. The threaded outlet directly mates with threaded pipes or instrumentation components. The integral reinforcement reduces stress concentration at the pipe opening and lowers the risk of cracking. Field installation is fast and convenient.
5.Core Difference between Latrolet and Elbolet:
Threaded Latrolet has a curved base matching straight pipe, providing a 45° threaded branch from straight pipe runs. Threaded Elbolet features a special curved profile to perfectly fit the outer surface of a 90° elbow; it can only be installed on elbows rather than straight pipe sections.
6.Quality Control & Testing:
All fittings undergo strict inspection including dimensional verification, visual check, liquid penetrant testing (PT) and
ultrasonic testing (UT). Thread gauge inspection is performed to guarantee thread accuracy. Material test certificates are
supplied with finished goods for traceability.

718 Threaded Latrolet/Elbolet Produce Processing
1. Raw Material Inspection：
All raw steel bars and forging blanks are strictly inspected before production. Chemical composition, mechanical properties and internal quality are verified in accordance with MSS SP-97 and relevant material standards. Unqualified materials are rejected to ensure overall product reliability.
2. Hot Forging and Blank Forming：
Qualified raw materials are heated and precision forged into integral Latrolet and Elbolet blanks. The forging process eliminates internal porosity, refines grain structure, and improves mechanical strength, toughness and pressure resistance of the branch fittings.
3. Heat Treatment：
Forged blanks undergo standardized heat treatment including normalizing, quenching or aging according to material requirements. This process stabilizes the metallographic structure, relieves forging stress, and ensures stable hardness and high-pressure performance.
4. Precision CNC Machining：
The blank is processed by CNC turning and milling. The saddle curved surface, outer contour, inner hole and welding bevel are precisely machined to fit the main pipe or elbow perfectly. All dimensions strictly follow standard tolerance requirements.
5. NPT Thread Machining and Calibration：
Standard NPT internal threads are precisely cut on the branch outlet. Each thread is inspected with professional thread gauges to ensure accurate taper, smooth tooth surface and reliable self-sealing performance for threaded connection.
6. Non-Destructive Testing and Quality Inspection：
All finished products undergo visual inspection, dimensional inspection, PT and UT non-destructive testing. Surface cracks, internal defects and dimensional errors are fully checked to meet industrial high-pressure piping standards.
7. Surface Treatment and Packaging：
Qualified fittings are cleaned, polished and rust-proof treated. Product marks such as size material grade and heat number are engraved. Finally, finished products are packed with protective materials and accompanied by complete inspection documents for delivery.
