High-pressure movable elbow
The produced movable elbow is a metal pipe joint with ball bearing, with its specification being 1"4" and
its rated working pressure being 14140MPa( 2000psi20000psi); It is feasible to provide various models
of movable elbows used under ordinary temperature, low temperature and sulfurous gas as well as the
maintenance packages.
The movable elbows have 2 types: long radius elbow and short radius elbow. The major radius movable
elbow has smooth drift diameter, which can minimize the resistance generated when liquid passes; The
resistance to erosion and corrosion of fluid for the wall thickness at the turning position of long radius elbow
is better than that of short radius elbow. However, long radius elbow is also used in consideration of the
limit of field installation space or lower pressure.
JIANGSU HAOTIAN PETROLEUM EQUIPMENT CO.,LTD
The blank bend of movable elbow is molded on the numerical control machine, which has even wall
thickness and long service life. The wall thicknesses difference at the positions of inside and outside
circular arcs reaches FMC standard, and its appearance quality can match with the imported blank;
The movable elbow has 3-ball groove design, so that it can effectively bear overload and radial load, it is
stable at the time of bearing pressure and the vibration in pipeline is smaller at the time of bearing various
loads;
All the specifications of movable elbows are the same as the like products produced by FMC Company,
and their coupling dimensions completely comply with American standards, so that they may replace the
like products of FMC Company used for well cementing and fracturing equipments.
The sealing element is made of synthetic rubber, equipped with the blowout prevention ring and
designed with the pressure release vent, so that it is possible to automatically reduce pressure in case of
any leakage in the sealing element to prevent the pressure from being accumulated in the ball groove
cavity, and thus greatly improving its safety;
For the field maintenance of movable elbow, it is only required to make lubrication occasionally to
ensure its normal operation.
Union
The hammer unions which are produced on the basis of the absorption and digestion of the technologies
transferred by American SPM and are used for connecting various pipeline include threaded connection
type, welded type and hydrogen sulfide gas resisting type, with the specification being 1"4" and the cold

Credibility seal performance : The seal ring is made of imported sizing materials through compression, so that its loading capacity and
sealing property are improved greatly and prevent the joint from corrosion. The sealing types differ
according to the pressure and application range.
Quick installation: Regardless of position and space, the wing nut and rigid self-locking type ACME thread are so designed
that they can be quickly tightened and dismounted without using special tools.
Highly interchangeability: The structure and coupling dimension of all the unions comply with the international product standards, in
the unit of inch size; the seal rings of unions completely may be interchanged with the products of American
SPM and FMC companies; the marks of specification and pressure on the wing nut are formed through
one-time die forging.
Advanced processing and inspection means: The spherical joint processed by the high-precision numerical control machine and the LP thread
processed by the imported special cutter provide reliable guarantee for high pressure seal; All the wing
nuts are processed by the numerical control machine, which have no relief groove, so that the product may
have sound strength and high bearing pressure; The materials for welding unions and the dimension of
welding bevel comply with the requirements of APISPEC16C specification; The unions used under the sour
environment are designed and manufactured according to American NACEMR0175 "Sulfide Stress
Cracking Resistant Metallic Materials for Oilfield Equipment" and APIRP- 14E standard.

Annular Manifold
The produced annular manifold is applicable to the discharge pipeline, infusion pipeline, well testing
pipeline and well cementing mud line used for various high-pressure operations of oil field as well as the
other liquid flow transfer lines under high-pressure operating conditions, which is composed of movable
elbow and straight pipe assembly. It increases flexibility and durability, so that fluid can flow more smoothly.
In addition, it can be quickly installed and conveniently disassemble/assembled; At the time of field use, it
is feasible to realize the connection with the pumper or the other ground manifolds only through opening
the union cap at the position of union assembly.
The annular manifolds mainly include 3 types: Short-radius movable manifold, long-radius movable
manifold and integral movable manifold, with specification being 1-1/2", 2", 3" and 4" and working pressure
being 35MPa105MPa( 5000psi15000psi).
The movable elbow equipped for annular manifold has such characteristics as flexibility, shock resistance,
