Posted
on June 21, 2013
If,
you are going procutre a new Y Strainer for your proejcts and
think for long life and easy maintenace of it, here we provide
check list which will helpful to you to select a best quality
y strainer. In a market cheapest and costly strainers are
avaialbe but without of below point cover your strainer is
meaningless to install and not perfrom well as it should. When
you are going to fit strainer in line thinking somany
advantages of it like extend life of pump, remove foreign
particle surely, increase quality production with minimum
shutdown, easy cleaning of strainer filter element, less
cleaning of filter etc, but if you fail to choose proper
product then zero advantage.
1.
What is Filtration Area across the Line for quoted strainer?
2. Any
calculation available for Filtration Area surity?
3.
What is Pressure Drop - Delta P for quoted strainer?
4. Design
standard of Y Type Strainer?
5.
Arrangement of Drain?
6.
Online Filter Cleaning Provision?
7.
Is there provision to mount Differential Pressure Gauge?
8.
Bolted Cover design to easy open cover?
9. How reliable Casting Quality of Y Strainer Body?

Why
Magnetic Type Strainer?
What is advantage of Magentic Y Strainer?
Investment Casting rugged body construction bolted cover
Magentic Type Strainer design have main advantage is to stop
Iron (Mild Steel or Carbon Steel Metal) particle in line at
strainer element. By the use of fine mesh can also stop any
other sand, dust, mud or metal particle. Inside the strainer
body have provision to fix a HIGH FREQUENCY MAGENT
which help to stop iron particle. Mostly magenetic type
strainer used is Stainless body version a grade of ASTM A 351
GR. CF8 (Stainless Steel 304), ASTM A 351 GR. CF8M
(Stainless Steel 316), special grade also available on
request.

Purpose of Jacketed
Valve
Posted
on February 25, 2013
Main purpose for using of
Jacketed Valve is to maintain continuous free flow of pipe
line in liquid or flowable mode by the help of Jacket
surrouing valve body. Wherever in industries material solidify
at normal temperature like Sulfur, Asphalt, Coaltar, Bitumen,
Visous media etc, their mostly pipe line, valves & pumps
modify by Steam or Hot Oil Jacket. Mostly
all Jacketed valve flanges are one size higher due to proper
easy bolting clearance at flange. Same size as line of flange
valve also can do manufacturing but in that case jacket will
be half / partial type.

5211 Direct Mounting Pad Ball Valve Advantage
Posted
on January 1, 2013
Direct
mounting pad ball valve allows pneumatic, electrical,
motorized actuator or quarter turn worm - gear box can be bolt
easily directly on the mounting pad (as per ISO 5211 standard)
of the valve body. By the ISO Direct mounting pad design any
time easily to switch over by manual operation to automation
by pneumatic or electrical without requirement of any extra
parts.
No
requirement of any extra mounting brackets, couplers or
distance piece to joint connectors between valve stem and
actuator/gear box are required. The bottom of the actuator or
gear box is rest on the ISO 5211 mounting pad flange of the
valve body.
No
extra moving parts in this design which benefit is no chance
to twist of any parts after a long operation of valve. Due to
absence of bracket, adapter and coupler no chance of any
corrosion. Direct mounting pad design ball valve avoid a
number of problems and extend a operation life of valve.
Simply Engineering advantages of ISO 5211
