A connector includes a connecting body with a fluid passage at least part way therethrough, and a seal is provided with an outer portion of a fluid tube. A cartridge proximate to the connecting body has a hollow portion therethrough. A grab part has at least one tooth to retain the fluid tube and is between the cartridge and the seal. A demount part within the hollow portion moves the teeth to allow release of the fluid tube. A latch is located on one of the connecting body or a sleeve covering at least part of the cartridge or the connecting body. A mating catch is located on the other of the sleeve or the connecting body, and engagement of the latch with the catch connects the sleeve to the connecting body and helps restrain cartridge movement.

The present invention relates to a header configuration block for a hydrocarbon well comprising a header configuration block housing having a plurality of transversal bores each in fluid connec-tion with a discrete longitudinal main bore. At least one cut off valve is located in each transversal bore. A first connecting surface is parallel to and similar with a second connecting surface, whereby the first connecting surface and the second connecting surface are adapted to be connected to at least one further similar header configuration block. The invention also relates to a manifold branch configura-tion block and a well fluid manifold assembled of header configuration blocks, branch configuration blocks and flow line configuration blocks.

A modular fluid-carrying manifold apparatus is provided for use in hydraulic fracturing blenders and other devices. A manifold can include one or more interchangeable sections. Each section may have a flat front face with ports cut into the front face. Components such as valves and hammer unions are directly removably connected to the ports via bolts. This eliminates the need for welded-on piping. Removable, wear-resistant inserts can be located in the ports. The removable components may be considered consumable and replaced when worn out.

A system may include a manifold having a plurality of fluid inlets, a first pump truck having a first pump disposed thereon with a first fluid outlet, and a first flexible pipe. The first flexible pipe may include a first end of the first flexible pipe coupled to a first of the plurality of fluid inlets, a second end of the first flexible pipe is coupled to the first fluid outlet, and a first outer shell mounted on the manifold. The first outer shell may extend from the manifold a length between the first end and the second end. Additionally, the first outer shell may be curved to have a radius to arch the first flexible pipe from the manifold to the first pump truck.

A joint includes a first block, a second block, and a single pipe section connecting the first block and the second block. The first block, the second block, and the single pipe have a first gas passage and a second gas passage inside therein. The first gas passage is formed so that a first port which opens at an outer surface of the first block, the single pipe section, and a second port which opens at an outer surface of the second block communicate with each other. The second gas passage is formed so that a third port and a fourth port which open at the outer surface of the second block communicate with each other. The second port is disposed between the third port and the fourth port.
