Metal pipe fittings
Jiangyin Tianning Metal Pipe Fitting Co Ltd, founded in 1990, specialises in
the manufacture of straight and reducing tees, 90° and 45° elbows, concentric
and eccentric reducers, caps, crosses, stub ends, flanges and forged fittings,
according to ASME, ANSI, MSS, JIS, DIN, GB, SH and HG.
The products range in size from ½" to 64", in thicknesses from SCH5S to
SCHXXS. The products have been supplied to major projects for domestic
and international markets, and are used in oil and gas, power plant, chemical,
metallurgy, electricity, ship-building, paper making and water supply industries.
The company’s strict inspection policy covers every aspect of the production
process, from purchasing of raw material to delivery of products. The company
has obtained ISO9001:2000 quality management system certification, PED
97/23/EC, AD2000-Merkblatt/W0 certifications under TÜV approval, and has
become a supplier member of Sinopec Materials Source Market and National
Petroleum Corporation Materials Source Market.

Beswick Engineering has launched
manifold mount versions of its miniature
pressure regulators. These models
include the PRDB8 high accuracy,
single stage pressure regulator, PRD28
two-stage pressure regulator, and the
PRDHF8 high flow regulator.
The PRDB8 regulator is amanifoldmount
version of Beswick’s PRDB pressure
regulator with a patent-pending valve
mechanism designed to provide high
precision/high reliability at low flows
and at low set pressures. It controls
output pressures from 0 to 30 psig
and is particularly suited to regulating
pressures as low as 0.5 psig.
The PRDB8 connects via a 10-32 UNF
threaded port. Its maximum supply
pressure is 500 psig and it weighs
approximately 25g in stainless steel. The
PRD28 two-stage manifold regulator can
also accurately reduce high-pressure
inputs (up to 500 psig) down to 0 to 20
psig.
It is designed to regulate pressures as
low as 0.5 psig, and exhibits minimal
droop and rise even with wide swings in
inlet pressure and flow.
The regulator is suited to applications
such as regulating fuel gas pressures
from storage tanks, where the inlet
pressure decays significantly over time.
The PRDB28 connects via a 5/16-
24 UNF threaded port and weighs
approximately 52g in brass.
The PRDHF8 regulator is used in
applications that require higher flows
Miniature manifold mount style
pressure regulators
than those supplied by the PRDB
pressure regulator. It controls output
pressures from 0 to 30 psig and is
designed to regulate pressures as low as
0.5 psig. Maximum inlet supply pressure
is 500 psig. The PRDHF8 connects
via a 5/16-24 UNF threaded port and
weighs approximately 52g in brass and
stainless steel.
Typical applications for these pres-
sure regulators include hydrogen fuel
cells, medical equipment, instrumenta-
tion, laboratory equipment, ink jet print
engines and semiconductor manufac-
turing equipment. The PRDB8, PRD28
and PRDHF8 have patents pending.

Aluminium flanges
Fonderia Fazzini has produced
aluminium flanges for 40 years. The
company’s range includes loose flanges
for collars for steel pipes according
EN-DIN-ANSI standards PN6, PN10,
PN16, 150LB; blind flanges PN 10/16;
loose flanges for PE/PVC plastic pipes
UNI-DIN PN10/16; and special flanges
according to customers’ drawing.
The company’s patented Lite flanges
feature an exclusive truncated cone
shape, allowing them to be 30% lighter
than current aluminium flanges.
Loose aluminium flanges are an
interesting alternative to those made
from other materials, and they benefit
from the characteristics of aluminium,
including light weight, hardness,
corrosion resistance and cost
efficiency.
