Technology account ：
The A. B.S. plastic pipe, pipe outfitting, valve take shape by extrusion and injection with A. B. S resin as raw materials. Its tripartite structure boasts many kinds of fixed performances, is the copolymer of propylene, butadiene, styrene, propylene with one CN gene, making the products have strength and enough hardness relatively , improve chemicalproof corrosivity, heat resistance. The butadiene molecule itself is ontoughness, short range repel strength and little inside rotate location, very small effect between molecules, compose the pliancy to the molecule link of the tripartite structure, making the products have certain elasticity, higher percussive resistant intensity under the low temperature, and difficult to bend while being fragile. The styrene makes the molecule link keep rigidity, the material endure, with luster and keep good electric performance and hot mobility, it is apt to process shaping and colouring.

The A.B.S. resin is shallow ivory white , opaque , nonpoisonous , tasteless , its comprehensive performance is better, a relatively ideal engineering plastics, adopted extensively by all trades and professions including aviation , shipbuilding , textile , automobile , building , chemical industry , especially water supply, water pilot, water treatment , food , brewing, medicine,is regarded as the first-selected nonmetallic materials.

The main performances of the premium A.B.S. resin can be manifested as bellow:
1． Boasts high percussive intensity in a quite wide temperature range.
2． Light weight, small investment, its weight is just one tenth of the steel, reduced the structure weight, 　　
　　labor intensity and material consumption, saving the engineering investment.
3． The heat distortion temperature is high with good stability of the product size.
4． Quite stable chemical performance, nonpoisonous, tasteless,comply with the health security
　　requirements of food, medicine, drinking water completely.
5． Its long life performance is in pace with the building, even longer under ground or in the water.

2． Pipe outfitting should in line with the following regulations：
（1） Pipe disconnection tool should select detailed tooth saw , cutting knife or special disconnection
　　　machines ;

（2） When disconnecting, the fracture should be levelled, is perpendicular to the pipeaxis ;

（3） Should remove the burr and of the fracture ;

（4） Should examine the cooperation degree of the socket while outfitting the pipe. Conduct pilot
　　　inserting of the socket , try inserting taking the 1/2-3/4 depth of it, and make marks.

3． The pipe conglutination should comply with the following regulations：
（1）It is not suitable to conduct pipe conglutination under great humidity
　　 environment,and the operation site should far away from fire source to
　　 prevent from the strike, should not conduct under -20 Centigrade
　　 degree；
（2）Applying the foam adhesive should use the bristle brush and the dry
　　 cloth used to clean the socket should not have oil mark and dirt；
（3）Before daub the foam adhesive, one should clean the conglutination
　　 surface of the socket with cloth and polish by the emery cloth；The
　　 conglutination surface should not have dust, water mark, and oil mark.
（4）While daubing the adhesive, one must daub the bear-mouth first , and
　　 then the socket. While daubing the bear-mouth should from the inside
　　 to the outside. The adhesive daubing should be even , right amount.
（5）After daubing the adhesive, the conglutination should finish within
　　 60s.；
（6）At the time of sticking , one should insert the socket gently in the
　　 bear-mouth , finish rapidly aiming at the axis. Should reach its bottom
　　 in the depth. Is can rotate slightly, but can't exceed 1/2 of the circles
　　 to insert and connect, can't insert to the bottom and then rotate (see
　　 the dynamic account);
（7）After finish the conglutination, the outstanding adhesive of the
　　 connector should be cleaned immediately.
4.　The just finished-conglutination connector should avoid receiving
　　strength, must continue installing after a certain time of quiet
　　solidification.

5.　Operating under zero centigrade degree should not't make the adhesive
　　freeze , can't adopt flame or electric stove to heat the adhesive. The
　　solidification of the connector should lengthen correspondingly .

6.　After the pipeline is connected, the solidification can come into operation
　　24 hours later,the measure index is 72 hours as solidification.
