Mandrel, SIFO-1EC 2.375" 4.7# EUE BxB with 1/2" NPT | Side-Pocket Gas Lift Mandrel – 4130 LHT, H₂S Service Rated
Product Overview
The SIFO-1EC 2.375" EUE BxB Gas Lift Mandrel is a high-integrity, side-pocket mandrel designed for casing flow gas lift operations. Constructed from 4130 LHT alloy, this inseparable mandrel is built for sour service (H₂S) environments and supports external pressure testing, internal pressure ratings up to 6000 psi, and high tensile loads. Its robust side-pocket design enables valve insertion/removal under pressure and makes it ideal for artificial lift optimization programs in deviated or high-pressure wells.

Frequently Asked Questions (FAQ)
Q1: Is this mandrel certified for sour service (H₂S)?
A: Yes — manufactured from 4130 LHT and designed for H₂S compatibility.
Q2: What is the difference between WC-349 and QPP-236 coatings?
A: WC-349 is the external coating procedure (painted); QPP-236 is for internal protection.
Q3: Can I use this in tubing-conveyed gas lift operations?
A: Absolutely — designed for tubing-integrated EUE 2.375" configurations with side-pocket valve access.
Q4: Does it come with valve or latch assemblies?
A: No — sold as mandrel only. Compatible valve options and latches sold separately.
Q5: Are test reports or documentation included?
A: Yes — MTRs, pressure test logs, and QC release documentation can be included upon request.
