The steel pipe cross is used when there is a branch on the main pipeline that needs to be connected. When the size of the branch is the same as the header pipe equal cross is used and when the branch size is less than the header size, then, unequal cross is better. Our company applies hydroforming and hot press forming to manufacture steel crosses which are made of seamless pipe. Hydroforming can complete steel pipe cross shape forming at once, thus getting high efficiency.
Materials for making our pipe cross are often low carbon steel, low alloy steel and stainless steel to strain hardening tendency. Cependant, if hot press forming technology is adopted and equipment required is of small tonnage. Besides, large diameter and large wall thickness steel cross are usually manufactured by means of hot press forming.
The maximum wall thickness of the steel pipe cross is 150 mm and some schedule numbers are sch10, sch20, sch30, norme, sch40, sch60, xs, sch80, sch100, sch120, sch140, sch160, xxs, sch5s, sch20, sch40 et sch80. Our steel cross and related pipe fittings are widely used in electricity, gasoline, pétrochimique, ship building, heat supply network, paper making and metallurgical industries among others.

CARBON STEEL BUTT WELD FITTINGS
- ASTM A234 Carbon steel Cross – Wrought Carbon and Alloy Steel Butt Weld Fittings : This specification covers wrought carbon steel and alloy steel butt weld fittings of seamless and welded construction. This is the most common material for carbon steel butt weld fittings (specifically grade WPB) and is seamless up to 24”, where diameters of 24” or larger may come seamless or welded. These butt weld fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.
- ASTMA860: This specification covers wrought high-strength ferritic steel butt weld fittings of seamless and electric fusion-welded construction covered by the latest revisions of ASME B16.9 and MSS-SP-75. These butt weld fittings are for use in high-pressure gas and oil transmission and distribution systems.
STAINLESS STEEL BUTT WELD CROSS FITTINGS
- Seamless and Welded Stainless Butt Weld CROSS FITTINGS: This specification covers the standard for seamless and welded wrought austenitic stainless steel butt weld fittings for pressure piping applications.
Pipe fittings are used in plumbing systems to connect straight sections of pipe or tubes, to accommodate different sizes or shapes, and for other purposes such as regulating (or measuring) fluid flow. These fittings are used in plumbing systems to control the transfer of water, gas or liquid waste within pipes or plumbing systems in domestic or commercial environments. Raccords (especially uncommon types) require money, time, materials and tools to install and are an important part of plumbing and plumbing systems. Common pipe fittings mainly include: bride, elbows, accouplements, unions, spools, reducers, bushings, tees, diverter tees, crosses, casquettes, plugs, barbs and valves. Although valves are technically fittings, they are usually discussed separately.
Les corps des raccords de tuyauterie sont généralement constitués du même matériau de base que le tuyau ou le tube auquel ils sont connectés.: cuivre, acier, PVC, CPVC ou ABS. Tout matériau permis par la plomberie, codes de santé ou du bâtiment (le cas échéant) peut être utilisé, mais il doit être compatible avec les autres matériaux du système, le fluide transporté, et la température et la pression à l'intérieur (et dehors) le système. Raccords en laiton ou en bronze sur cuivre Courant dans les systèmes de plomberie et de plomberie. Résistance au feu, résistance aux chocs, résistance mécanique, l'antivol et d'autres facteurs affectent également le choix du matériau pour les raccords de tuyauterie.

Les réducteurs concentriques sont utilisés lorsque la tuyauterie est installée verticalement et du côté refoulement des pompes.. Les réducteurs excentriques sont plus souvent utilisés lorsque la tuyauterie repose sur un support à tubes. A cause du côté plat, l'alignement et le montage sécurisé des tuyaux sur le rack sont plus faciles.
Bouchon à souder bout à bout Nous sommes fabricant de bouchons à souder bout à bout et fournissons tous les programmes dans des types de matériaux tels que l'acier au carbone., acier inoxydable, acier allié. Zizi produit des bouchons de tuyaux en ASME, DEPUIS, JIS et autres normes requises.
