Product Description

The size of the head


Reducer reducer decorated capitulum, reducer, and went all the way through.One of the chemical pipe fittings, used for two different tube


The connection between the diameter of the pipe.According to the shape of the different, divided into concentric big small head and eccentric reducer.


Size head size materials including stainless steel (304304 l316316l), alloy steel, carbon steel reducer, reducer


Made of 20 # steel and Q235, Q345, 16 mn etc.The main producing area in hebei province and taking mengcun hui from salt mountain county


County area.




National standard American standard British standard as well as a variety of non-standard products.


Power division standard GD0506 ~ 0507 form a complete set of pressure vessel flange, tubesheet corresponding standard: JB/T4700-4707 -


2000 national standard (GB/T9112-2000), the mechanical standard (JB/T81-1959, JB/T74-1994


), plus standard (SH3406-1996), Marine standards GB/T10752-1999, the chemical standards


(HG/T5010-1958, HG/T20592-2009), and so on.Export forged steel flange in the American ASTM material


A105 standards.


Seamless reducer


Reducer (reducer) is a kind of pipe fittings used in pipe size.Usually adopted for reducing the forming process of repression


And hole enlargement to neutralize or reducing hole enlargement, for some specifications of the reducer and stamping can be applied.


Reducing/forming hole diameter


Size reducing forming technology of the head is with the head big end diameter equal to the size of the pipe into the forming mould, pass along


Tube axial direction of repression, shrink along the cavity movement and metal forming.According to the size of the reducer reducer,


Divided into one of pressing or more press forming.


stamping


Besides using steel as raw material to produce the size of the head, on the part of the specifications of the size of the head can also be used steel plate by stamping


Process for production.Used by stretching die shape inner surface size design, with reference to the size of the head with the die


After the steel plate stamping stretch forming.


Size head before bonding, use dry cloth to bell mouth and socket lateral wipe the handle, must be used when the surface with oil pollution


Acetone is wiped clean, have the following points to note:


1, control diameter: DIN standard (DN10-6), 3 a/IDF criteria (1/2 "to 6"), which ran on ISO standards


(12.7-152.4 Ф Ф);


2, the international industry standard: DIN, ISO, SMS, 3 a, IDF, etc;


3, the product material: 304, 316, 316 l stainless steel;


4, quality and use: size head inside and outside processing with high-grade polishing equipment, meet the surface precision requirements;This product


Applicable to the dairy, food, beer, beverage, pharmaceutical, cosmetics and other industrial fields;


5, external processing, can according to user requirements to map, sample processing non-standard products;


6, connection mode: clamp (fast), welding, thread (live).


Pay attention to the size of the head is also suitable for pipe diameter changes in environmental protection industry, are generally steel plate welding and cutting


Into, pipe diameter sizes and materials




Standard system of folding


The pipe flange on international standard, there are two main system which represented by Germany DIN (including the former Soviet union) European tube


Flange system and represented by the United States ANSI flange pipe flange system of America.In addition, Japan JIS


Tube flange, but generally only used in petrochemical unit for the utilities, and less affected in the world.now


Will the tube flange profile below:

Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon luo drain, PVC, PPR, RFPP (reinforced polypropylene


Ene), etc.


In producing method


Can be divided into pushing, pressing, forging, casting, etc.


In manufacturing standards


Can be divided into the national standard and electric standard, vessel standard, standard, water standard, American standard, Germany standard, Japanese standard, the standard and so on.


Radius of curvature to points


Can be divided into long radius elbow and short radius elbow.Long radius elbow refers to its radius of curvature is equal to 1.5 times of the pipe


Outside diameter, that is, R = 1.5 D;Short radius elbow refers to its radius of curvature is equal to the pipe diameter, R = 1.0 D.(D to bend


Head diameter, R for the radius of curvature).5. If according to the grades of pressure points: about 17 species, and the tube of the United States


Is the same, the sub standard has: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD,


Sch40, Sch60, Sch80s, XS;Sch80, SCH100, Sch120, Sch140, Sch160, XXS;its


STD and XS is the most commonly used in two kinds.
